Instructions Catch skull. READ STEP ONE AND ALL WILL BE CLEAR 88%
Ive been going through the Q and A lately and there has been a large number of questions about the Catch skull and many different answers, so here is how to get it once and for all.

1) (MOST IMPORTANT) Beat campaign on normal, or else it wont work

2) Go on the level the storm, start from the beginning an play it on normal

3) Go through the level until you get to the long hallway with many enemies in it. Destroy all the enemies.(without grenades)

4) At the beginning of the hallway face the opened door and look to your left you should see a ledge get on the ledge and walk to the wall on your left, there should be a bubble shield grab it and walk into the area with the wraiths

5) Walk down the ledge and by a few broken walls/rocks, there wil be a warthog

6) flip the warthog and ride it to the round building without destroying any wraiths

7) get out of the warthog and place the bubble shield

8) now use the warthog and a grenade jump to get to the top of the building

9) wait until the skull spawns and then pick it up like you would with a normal weapon

So, the main problem people having is that they have NOT completed the campaign on normal.

Stay Smexy guys!

Cloning 86%
Ok, first thing you need is a map such as Sandbox, or, Foundry. How to get these maps you ask? You need X-box live and microsoft points. To get microsoft points go to gamestop or any other place like that. Any way, back to the walkthrough. First delete everything on the map. Next build a box out of shield doors from the scenery menu. I almost forgot to tell you to set the damage resistance to 10 before you start the game. Ok so back to during the game, you put a soccer ball/golf ball in the shield door box(it'll spaz out a bit). Then you put down some turrets(doesn't matter what kind) from the weapons menu next to the box. Your done building now. To clone, run in the box until you get hit by the ball and your shields go down, and then you get on a turret and rip it off. If done correctly, you should die and your clon should be standing like he has a detached turret in it's hands. Happy cloning!

Kamikaze and other delayed effects 101 86%
Ok, this only works on forge. for the kamikaze, let someone stick you with a plasma or spike grenade. then, right when you get stuck, go into spark mode. it wont go off, and then charge at the guy who stuck you while still in moniter form. right when you get near them, switch back to the moniter. BOOM! you both go down. thats why its called kamikaze. *note- this doesnt work vice-versa* now, grab any type of equipment. start to throw it, but right when you press x, go into spark mode. then, go back to player mode. the equipment will drop. I like to do that with the flare, deployable cover, and power drain. if you use flare or power drain, as soon as you come back to player, switch back to moniter and run, so the effects dont hurt u. ok, the next and final one works ONLY with the sparten laser. charge it up, and a split second before it fires, go moniter. then, when an enemy is in your crosshairs, switch back. it will shoot the second you come back, so make SURE you have them in your crosshair. you wont have much time to aim, because they will soon notice u, even in spark mode. master this with the targets in the pit before you actually start to use it.

How to Kill Brute Chieftain easily on The Storm 83%
At the part after the Hunters enter, long after you destroy the Scarab, most people will directly run through the gate that the Hunters entered through. DON"T. Instead, before turning right to go through the gate, go straigtht up the stairs directly in front of you. Keep walking through the rooms until the last, where a sniper rifle is located on the ground beside a dead marine. For Easy, and Normal difficulties, it wouold be a great idea to start shooting from the window there. However, for Heroic and Legendary, it is more preferred to run back down the stairs and hide behind a truck while firing sniper rounds through gaps in the destroyed truck. Try to headshot the Brute Chieftain (it will take three hits on the head to kill him on Legendary) first. Then Take out the rest of the Brutes. So now, instead of dying so many times, you end up with a gravity hammer AND an Invincibilty equipment thingy. I hope this helped because I always had trouble at this area on Legendary.

P.S. DO NOT RUSH TOWARDS THE DEAD BRUTE TO GET THE TREASURE BECAUSE THERE ARE TONS MORE ENEMIES TO THE RIGHT. Instead, first strafe sideways left with your sniper and try to take out as many as you can. Then when your shields are almost all down, use your invincibilty and gravity hammer to punch out the Brutes' guts. If you still have rounds left with your sniper rifle, have fun sniping the Brutes arming the Anti-air gun!

Happy Hunting! =)

Ok, now we've all seen the little cutscene on crows nest with the two marines with rvb voices, so im not gonna talk about that. im sayin about other references. theres only two others I know of. the first is on the 'hog wheels, if you zoom in, you can just make out "puma", which is what griff suggested calling it on episode 2. the second is on bungie. net, when you check out your kills with various weapons on your profile, click on the flag. its description is, " right next to the headlight fluid", which is a referance to the job griff and simmons gave donut when he just came to blood gulch.

Kill The Brute Chieftain Easily on the Covenant 83%
Heres a great hint to get you going on the level the Covenant. In the first barrier tower, right at the opening where the Shade is, right beside the door ( left) that you will go through, is a Weapon Holder. And under it is a Cloaking device ( that glows blue). If you can't see it, walk over the area to the left of the door and you should be able to pick it up or if you have another piece equipment, ask you if you would like to switch to the Cloaking device. IMPORTANT!- DO NOT USE CLOAKING ANYWHERE BEFORE MEETING THE BRUTE CHIEFTAIN! If so, do go back to last checkpoint so you still have one in your inventory. Then when the elevator stops at the top floor, hide behind the glass sheen and use your cloak. Now run over to the Brute Chieftain, BEHIND HIM... and assasinate him. *** MAKE SURE YOU ARE NOT HIT BY ANYTHING ON YOUR WAY THERE. THis should easily allow access to the Gravity Hammer AND the Invincibilty. Then just finish off the other Brutes and deactivate the tower when you feel like it. I hope this has helped since I always had trouble fighting off Brute Chieftains.

Secret - HALO SECRETS: 82%
My secrets im listing now dont have skulls or terminals in it !

1.secret pack of cavemen
On lvl serra 117 to the bit just after that pelican got shot down and after you kill the brutes there should be a bit with lots of sniping jackals keep walking on your far left until there is a rock and on top of that rock is a jackal kill it a d there sould be a sticky out bit like this

Walk along that ledge ( the rubbish arrow is pointing to what I mean )thein once you have walked across it look to your far left corrner and there they are.

2.Brute doing up his zip
On the lvl the ark go all the way to the bit where the sleeping grunts are every were
go to the top right of the room and there is a brute witch must have been peeing up the wall doing up his zip ps:make sure not to wake up the grunts

3.The coverment
there are two secrets on this lvl so I will start with the first one

1)The anti air wraith
At the start of the lvl kill all the enemys and when you get to the anti air wraith (the goldish one)leave the grunts around it alive but kill the brutes and jump onto the wraith and crouch on the bit were he would get in shaped like this.

The x means that is the best place to stand and the v is witch way you should face.Look down wile your crouching make sure it dosn't say hold RB to do some thing to the thingy(I forgot what it says but if it says anything move about a bit when your crouching until it dosnt say anything on the screen).Thein meele (press B to whack/meele) the bit until it breaks open and you can see a brute driving still making sure you cant see any words on the screen Hold RB and start shooting the brute in the head until dead using a battle rifle or covernant carbine and since your still holding RB you sould get in (if you let go of RB or dont crouch and shoot him in the head but dont hold RB it wont work and if you do do it right you should get in but when you get out it expodes).
2)After you fight the first flood in the lvl when you get out of the building the arbeter should get in a phantom jump in it with him and your in it and it sould fly off thein turn invisible when it tuns invisible you sould fall through it and die.

4.lvl Halo I will write this one soon look for it but its got so many secrets and with my luck my computer would crash when ive write it all!

The many ways into a scarab 82%
Okay, now I know that you all know about the main entrance into a scarab, the open spot in a back. but, there are 3 others.

1- theres a small catwalk on either side of the scarab, thats an easier way in than facing the plasma cannon and the brutes, and you can avoid any enemies that way too, if your good enough at stealth.

2- theres a hatch beside the main opening, but you gotta blow it open with grenades, tank shots, or rockets. it makes no difference exept that you avoid the plasma cannon.

3-on every scarab, theres a way to get on it without making it kneel. on the first one, jump on the elevator near the missle turrets, then go to the end of the crane and wait till it comes near, and jump on it. on the second one, get to the top of the forerunner structure and wait till it comes near, and like the first one, jump on. on the third one, get in the hornet, and get above one, and jump out onto the scarab.

I jacked his gun and shot down a hornet(that was also I perfect condition) in one hit as well. so, I added gauss 'hogs to every map that has air support and can take a gauss warthog. and now, I am the ultimate G-A(ground to air) fighter. it works better than a sparten laser, cuz it shoots faster, and is more mobile so its harder to hit.

Floating bases!!! 80%
To make a floating part of a base, follow these steps:
1: Place a large object on a flat surface. BEst if using a radio antenna, crate, container, etc.
2: Place 2 reciever nodes upside down on top of the long sides of the object . Only 1 if using radio antenna, 2 for crates and containers.
3: Place another object, such as a crate or open container on top of the nodes that are on top of the bottom object, NO RADIO ANTENNAE, because then it it too high.
4: place 2 more reciever nodes, don't have to be upside down this time, on top of the top object the same way as you did the first object.
5: Delete the bottom object only, and now you have a floating base!
Extra: To add a rocket booster effect to the base, put a sender node with the same frequency as the 2 reciever nodes below the floating object anywhere on the map!

Awsome coverage on last resort 80%
On the multiplayer map, last resort go into forge mode and place a machinegun turret on the sniper post edge facing the giant power fan. if placed correctly this should give you coverage of most of one half of the map. (Only put turret counters behind you. E.G. Sniper rifles or missile or rocket launchers. )
This way you can eliminate most opponents swiftly withouth them knowing where you are! And if they escape you can simply rip off the turret and wait for them to appear again.

Infinite Spartan laser in Halo mission
Use the following trick to get a Spartan laser with unlimited ammunition in the "Halo" mission. Play through the level until you meet up with Sergeant Johnson. Shoot him until he falls down and drops the Spartan laser. Quickly pick it up, and shoot it at him. Keep shooting him until he kills you. When you respawn, knock him down again, and pick up his laser. He should get back up with another laser on his back. When he does, shoot him down again, and pick up the new gun he drops. This laser should now have unlimited Spartan ammunition. This makes it easier to destroy the Guilty Spark 343. -From: Camuel

Katana
Successfully complete all achievements (1000/1000) and find all Skulls to unlock the Katana.

Bonus downloadable content
Successfully complete the game on the Legendary difficulty to get bonus pictures and a "Making of" video from Xbox Live.

Alternate endings
There are three endings. The first ending is shown when the game is successfully completed on the Easy, Normal, or Heroic difficulty setting. The second ending is shown when the game is successfully completed on the Legendary difficulty setting. The third ending is shown when the game is successfully completed on the Legendary difficulty setting with all Skulls activated.

Easier Legendary mode
If you are playing alone on the Legendary difficulty setting, turn on an idle second player to stay behind. If you die, you will respawn instead of restarting.

Super fast Spartan laser fire
In Forge mode, get a Spartan laser. Charge it until it is almost about to fire. Before you fire, turn into the Monitor. Fly around until you find a target. Before you turn back into a human, hold RT to fire the Spartan laser almost instantly (if done correctly). You can use the Monitor's aimer to aim the laser.

Smarter respawning
When playing in Co-op mode on the Legendary difficulty setting, it is best to have one player keep their distance from the enemy at all times. By doing this, if the rest of the players die, they will respawn around the player that is farther back, rather than having to restart at the checkpoint.

Preventing lag
To clear the hard drive cache and prevent lag in Solo and Multiplayer mode, when starting the game, hold A + Up. Select "Yes" when you are asked if you want to clear the cache.

Easy experience in Multiplayer mode
Note: This trick requires four active accounts on your console that are all able to play on Xbox Live. Enter the matchmaking lobby, and choose "Social", then "Rumble Pit". Sign all four of your accounts in the lobby. In free for all modes, you have to be in the top three to earn experience points. Start matchmaking, and it should find two additional players. Once the game begins, you can simply do nothing. Once the game ends, all four of your accounts will tie for third place, giving all of them easy experience points. -From: Brandon Adkins

Skull locations
You can only collect Skulls on the Normal, Heroic, and Legendary difficulty setting. You must start from the beginning of the mission. You will not be able to see the Skulls if you load from a checkpoint, unless doing so after dieing. In Co-op mode, as soon as one player picks the Skull up, all players will receive the achievement if there is one. Not all Skulls earn an achievement only nine of them do. To use Skulls, press X at the lobby screen. This will give you a bonus multiplier for Co-op mode and go towards earning the Guerrilla, Demon, etc. achievements.

Black Eye Skull: At the start of the "Crow's Nest" mission, without moving anything, you can see a huge pipe above you. Walk up the stairs, then up the next set. Turn to your left and jump up on the shelf unit. Jump to the red cross beam, then up onto the pipe. Then, just walk to the end. Walk over the Black Eye Skull to collect it. You do not have to pick this Skull up, it does it automatically. The Skull description reads "Bash your way to better health." When this Skull is active, your shield will instantly charge when you use melee attacks, and will not auto-recharge anymore.

Blind Skull: In the "Sierra 117" mission, when you get to the area where you see the Phantom overhead (one of the marines will point it out), jump over the rocks, and keep following the path on the right. When you get to the cliff, there will be a rock over the side. The Skull is on the end of the rock. The Skull description reads "Shoot from the hip." Note: This Skull has to be activated before you start a campaign map.

Catch Skull: In "The Storm" mission, go to where the first anti-air Wraith tank is located. There is a large gray cylinder in the that area on the ground on the far side from where you enter. The Skull is on the top of the silo. To get up there, perform a grenade jump off a Warthog or use a vehicle to push a large crate to the side of it jump on the crate, then the silo. Note: Do not destroy the Wraith near the door or the Skull will disappear. The Skull description reads "Pull pin. Count to three. Throw." When this Skull is active, every NPC will carry two grenades and throws them often.

Alternately, take a Warthog, and park the front of it next to the cylinder. Take out a grenade (plasma recommended), and throw it at the front of the Warthog. Jump at the correct moment (usually as soon as you throw it) to get a little extra boost to your jump to get to the top to reach the Skull. This may require a few attempts.

Alternately, play in Co-op mode. Have a partner stand beside the building the Skull is on. Jump on top of them, then have them jump. At the peak of their jump, jump off of them. You will land next to the Skull. Collect it, then drop down to allow everyone else to get it.

Cowbell Skull: In "The Ark" mission, pick up a Grav Lift from the small building near where you fight the Scarab. Then, proceed through the level until you reach the second sloping hallway (stairway). You should see some partitioned risers (platforms) halfway down. The Skull is on the top level. Throw the Grav Lift on the right side of the hall so it lands on the fourth little green dot from the door. Then, run, jump, and use the Grav Lift to propel you to the top. You should reach a checkpoint just as you enter the room, so if you miss you can try again. When this Skull is active, explosive force is increased.

Famine Skull: In "The Ark" mission, when you first go into the valley to the right after the wrecked Phantom, look to your left to see a huge boulder. Use a Ghost to get to the side of the boulder that is closest to the bridge overhead. It is easy to pilot the Ghost up the side of the wall using the thrust. To get the Skull, pilot two Ghosts up the wall to the top of the bridge and stack them on top of one another next to the beam where the Skull is placed. Then, jump from the top of the Ghosts towards the Skull and land on the beam. The Skull description reads "Trust us. Bring a magazine." When this Skull is active, dropped weapons will have very little ammunition compared to normal.

Use the following trick instead of trying to get a Ghost to the Famine Skull or risking your life with a grenade. Instead of going straight to it, go the way you do later in the level with the tank. Kill all the enemies or until one drops a deployable cover. Go the way you would have. When you get over the hill, destroy the Ghosts. Go under the bridge. You will see a big rock with a pathway leading up. Follow it. When you get to the top, turn to your right. It will not have a dirt ramp, but a wall. Walk up to it. Notice the small ledge. Jump up, and walk all the way to the right. Deploy the cover so that it lands about halfway down to where the bridge slopes. Do not throw too far or it go over the ledge. Jump on top of the cover. Jump up to the narrow ledge to get the Skull. Note: There is more than one way to jump from cover to ledge try a few if you miss.

Fog Skull: In the "Floodgate" mission, as you are walking down from the anti-air gun you destroyed in the previous mission, there will be a ramp (next to a missile launcher). Around this ramp, there is a checkpoint. At this point, you should also hear a marine yelling, “There! Over There!”. Look up and to the right, directly at the roof of the building next to the missile launcher. There is a Flood form (not to be mistaken with the two other Flood forms jumping in front of you), which is holding the Skull. Kill him before he jumps, and he will drop the Skull down to the ground where you can retrieve it. Note: Correct timing is required because if you kill him too early, the Skull will get stuck on the roof. The Skull description reads "You'll miss those eyes in the back of your head." When this Skull is active, your motion sensor disappears.

Grunt Birthday Party Skull: In the "Crow's Nest" mission, immediately after the first objective, while en route to the barracks, you will fall down to a pipe. Go to the end of that pipe, then look over the edge to find a small space a few feet below. Drop over, then quickly pull back to land under the floor you dropped from. The Skull is at the end of this area. When this Skull is active, it makes Grunts explode in confetti when they are headshot. There will also be some cheering, like a birthday party.

Iron Skull: In the "Sierra 117" mission, after freeing Johnson and killing all the Covenant that come in the Phantoms, walk to the Pelican that arrives to pick you up. Face the cargo bay, but instead of going in, turn left and follow the path. Once you hit the wall, jump up to your right to eventually reach a walkway. Walk all the way to the end. Take a left, then a right. At the end of this, a little bit to the right is a dark corner. Press Up to turn your light on and you should see the Skull. If you cannot see it, you are probably standing on it. The Skull description reads "Death carries a heavy price...". When this Skull is active, instead of losing 25 points when you die, you will lose 75.

IWHBYD Skull: In "The Covenant" mission, go to the last tower. Before you get to the Prophet of Truth, there are a series of bridges with Halos. Do not jump through any yet. First, kill the Prophet of Truth, and defeat the bridges of enemies. Then, jump through the Halos in this order, with "1" being at the entrance and "7" being the end near where the Prophet of Truth was located: 4, 6, 5, 4, 5, 3, 4. Alternately, jump through the Halos in the following order: 4, 5, 6, 5, 7, 6, 5, 4, 1, 2, 3, 2, 7, 2, 1, 3, 4, 6, 7, 5, 4, 5, 3, 4. This is much easier in Co-op mode with three or four people. This is the Halo theme if it was played on a phone by dialing the numbers. If done correctly, the Halos will start flashing, and the Skull will appear near the Prophet's ramp. If the Halos do not flash, try again. The Skull description reads "But the dog beat me over the fence." When this Skull is active, there is bonus dialogue throughout the game. IWHBYD stands for "I Would Have Been Your Daddy", which is a level chapter from the original Halo. -From: crimsontwist

Mythic Skull: In the "Halo" mission, follow the normal path until you reach a cave. Follow the right wall until it branches off into a small path. At the end of this path is some rubble, and in front is the Skull. The Skull description reads "Coverage under the Covenant health plan." When this Skull is active, you will get a 3x score multiplier for all kills.

Thunderstorm Skull: In "The Covenant" mission, after you shut down the first tower and get access to the Hornet, fly to the second tower (the one the Arbiter shut down). While walking up the stairs, go to the middle part that connects both, and there should be stairs leading up to a platform where the Skull is. The Skull description reads "Field promotions for everyone!" When this Skull is active, enemies will be much stronger.

Tilt Skull: In the "Cortana" mission, when in the circular type room with all the Flood, look for a small structure piece next to two archways. Jump on top if it, then go up on the rocks to the top left. Turn left and jump up again, then turn 180 degrees and jump to the rocks across from you. Then, follow the rock sticking out and leading up on top of the original circular room. The Skull is in a pool of blood. The Skull description reads "What was once resistant is now immunity." When this Skull is active, enemies will have different body parts that are resistance to certain bullet types.

Tough Luck Skull: In the "Tsavo Highway" mission, once you get past the part where you are forced to leave your vehicle, you will go through a tunnel and onto an open freeway. Immediately after coming out of the tunnel, you will see a huge pipe with two yellow ladders. Climb the second ladder. You should see a Regenerator power-up. Proceed to your right onto a small platform ledge where the yellow chain link fence is located. Jump onto that ledge, crossing over the fence. Directly behind you should be a large column that is holding up the giant pipe you were just on. Below that is a walkway. Fall off the ledge onto the walkway. Walk to the end of that. You should see a hidden ledge with the Skull on it. A few attempts may be requires to jump across. The Skull description reads "Your foes always make every saving throw."

The following Skulls require the "Mythic Map Pack" bonus downloadable content:

Assembly Skull: Located on the central tower in Forge.

Orbital Skull: Go to where there are two roadblocks where you have to jump. The Skull is on top of the structure on the right.

Sandbox Skull: Fly towards the sunset, and turn around to find the Skull.

Terminal locations
The following is a list of all seven Terminal locations. To accomplish the "Marathon Man" achievement, when you find each Terminal, press RB to view the journal.

Weapon descriptions
Assault rifle: This is a very handy weapon to fight all enemies with, but not vehicles. It is useful against both Covenant and Flood and is available throughout the game.

Pistol/Magnum: This is a very powerful dual-wielding gun that has high firing power. The new pistol no longer has a small zoom and has very little bullets. It is useful against both Covenant and Flood.

SMG: This is as powerful as in Halo 2. It has been upgraded with higher firing power and has a recoil. It is useful against both Covenant and Flood but can be difficult to find. It can be dual wielded.

Battle rifle: This is a powerful burst-firing rifle that has high damage and high accuracy. It is better against Covenant than Flood. It is useful for sniping.

Shotgun: This is a low ranged but powerful weapon. It can hold small amount of ammunition but can fire in mid-reload. It is useful against both Covenant and Flood but is far more efficient when used on the Flood.

Sniper rifle: This is an extremely long-ranged rifle that can fire four shots in one round. This is the main weapon for sniping and usually takes two shots to kill in the torso.

Rocket launcher: This is an extremely high damage weapon that is good for taking out powerful opponents and vehicles. It is also useful against groups of enemies. It has splash damage. Be careful as it can also be hazardous to yourself.

Spartan laser: This is the most powerful weapon in the game but requires a long charged wait. It is useful for killing vehicles and powerful enemies. It is vital to kill the Monitor.

Plasma rifle: This is a powerful weapon that is great against the Flood. You can dual-wield them, but they will overheat if fired for too long.

Plasma pistol: One fully powered shot can take out your shield. A powerful but difficult weapon to use. It can be dual-wielded. It is useful because of its high range and high attack speed. It is better against Covenant.

Brute spiker: This is a Brute weapon that is commonly used throughout the game. It has a medium-sized clip and can be dual-wielded. It is more powerful against Covenant.

Needler: This can no longer be dual-wielded but is much more powerful. It can now explode with four needles. It is useful against a group and powerful opponents.

Carbine: This is a Covenant version of a battle rifle. It is very useful for sniping and in close combat. It fires single shots and has an average round. It is commonly used by Jackals.

Brute shot: This is a less powerful splash weapon that is useful for taking out groups or vehicles. It has a high range and is very common throughout the game.

Beam rifle: This is a Covenant sniper-rifle. It does not require clips but cannot be fired repeatedly due to overheating. It has high range and is powerful against Brutes.

Energy sword: This is a melee weapon that is extremely powerful against one opponent, usually resulting in a one-hit kill. It is useful against both Covenant and Flood. It has a small rush towards the target before striking.

Gravity hammer: This is a rare and powerful melee weapon. It is only used by extremely powerful Brutes. It can take out groups and can push opponents away. It has a tiny rush when attacking.

Frag grenade: This is a powerful and dangerous grenade that has the highest kill-radius. It has a bounce that can make killing opponents difficult.

Plasma grenade: This is a weaker grenade that can stick to opponents and detonate, killing those around it. It sticks only to opponents.

Spike grenade: This is a less powerful but lethal version of the plasma grenade. When detonating, it sends spikes shooting in all directions. It can stick to both opponents and vehicles.

Firebomb grenade: This explodes on impact spreading flames around the area. It has a burning effect that is good against Flood more than Covenant but can spread.

Recharge shields quicker
If your shields are down in Forge mode, press Up and they will recharge.

Reload quicker
If you are a Spartan or Elite and your ammunition is low, press Up again while reloading to instantly reload.

Melee faster
To melee quicker, press B, then press Y(2), B rapidly.

Stay zoomed in
If you are zoomed in as a Spartan or Elite and turn into the Monitor, press Up to turn back into your character and still be zoomed.

Crouching
To crouch, click and hold the Left Analog-stick. While crouched, you will not appear on motion-sensors. This is helpful in Multiplayer mode when you do not want the other team to find out where you are.

Play as the Oracle
At the Forge lobby, press Up to turn into the Oracle. You can pick up items by pressing A when you see a green hand.

Exploding grenades
Throw a grenade in the air, and shoot it with a sniper rifle.

Defeating Flood
When you kill any Flood that can come back to life by the infection forms, hit the body and it should break apart. This saves ammunition.

Defeating Wraiths
To easily kill a Wraith and save time and ammunition, aim at the little circle on its back. It only takes approximately five to ten shots to kill it this way.

Illegal service tags
If you go to "Appearance" and try to change your service tag to "I17" (Master Chief's number is 117), the game will not allow it. It will say that the tag is reserved for use by the UNSC.

If you try to use "A55" as your service tag, you will be told that it cannot be used under UNCS regulations and rules.

Driving vehicles through invisible walls
In certain levels in Campaign mode, you may want to take your vehicle through most of the level. However, there are invisible walls that keep the vehicle from moving past where it is needed. To pass through this, drive your vehicle through the doorway, gate, tunnel, etc. where the invisible wall is located. Just before you go through it, jump out and let the vehicle pass through the wall. This allows you to take the vehicle through the rest of the level if desired.

Go under map in Construct multiplayer map
To do this trick, you must be in Forge mode. Make sure you sell a respawn point before doing this glitch. Start out as the Oracle. Go down the pink Grav Lift by using your boost (press LT). There should be a few holes. You cannot fit down these as the Oracle. Start boosting into one of the holes that is not a closed circle. The Oracle should go slightly lower into this hole. Make sure you keep holding boost, then turn into either Spartan or Elite. You should fall underneath the level. Make sure you drop a respawn maker on a place where you can stand so you can get back whenever desired. To confirm you are under the level, try to fly up without going through the Grav Lift. There is an invisible wall just like in the "Foundation" level in Halo 2, except on the bottom. Note: This may require a few attempts.

Dribble Skull in Crow's Nest mission
At the beginning of the mission, grab the Skull on top of the large pipe near the ceiling before you pick up any weapons. This is easier in Co-op mode. Press RT repeatedly. This will cause Master Chief to drop the Skull, but because he has no weapons, he will immediately pick it back up, making it appear as though he is dribbling the Skull like a basketball.

Red vs. Blue reference in Crow's Nest mission
When you begin the mission, you will find a large roadway with many Covenant forces. You are supposed to fight your way to a door that will lead you to a room with two turbine-like objects. Instead of going through this door, follow the road all the way to the end, killing all the Covenant on the way. Once you reach the end, there will be a Marine knocking on a door wanting to get in. If you listen closely, you can hear that it is actually an excerpt from Red vs. Blue where Simmons is talking to Griff trying to get into the base. Note: There is a different message for each difficulty setting:

Easy: None

Normal: Two Marines copying Red vs. Blue.

Heroic: Simmons and Griff from Red vs. Blue.

Legendary: Church and Caboose doing a "remake" of Simmons and Griff.

Leave level boundary in Highground multiplayer map
Go down to the beach area in Forge mode, and get in a Mongoose. Have the person in the Mongoose accelerate at the barrier. Afterwards, have the Wraith boost at the back of the Mongoose from a short distance. For a brief moment the Mongoose will be past the barrier. When this happens, get out. You will then be outside of Highground. This trick works in all ocean maps.

Evil duck in Isolation multiplayer map
In the "Isolation" multiplayer map, go to the Flood cave where the Ghost is located. Go in front of the Ghost, look up, and walk a short distance slowly. You will see a big smudge on its face, but look carefully for the duck's body. You can partly see its face and the horns on its head. This is related to the picture in Zanzibar in Halo 2.

Leave level boundary in Isolation multiplayer map
While in Forge mode, get as high as possible as the Monitor. Spawn a teleporter on the ground. Then, hug any wall while still being as high as possible, and spawn another teleporter. If the teleporter beneath you is lit up as it should be, turn back into a Spartan or Elite, then go through the it. You should now be outside the level boundary.

Stretchy Master Chief in Last Resort multiplayer map
While in Forge mode, move to the two Mongooses next to the building on the far side of the map from the beach. Change into the Monitor, and place six or more Fusion Coils near the side of the bridge coming out of the building. Change back to Master Chief, and stand on top of the coils. Position yourself so that when they detonate you will fly into the side of the bridge. This may require a few attempts. Then, end the game. Go to the theater and watch the movie. Play the explosion slowly by tapping A quickly to pause and restart the movie. If done correctly, upon impact Master Chief will stretch out.

Flipped Elephant message in Sandtrap multiplayer map
Note: This trick is best done with two players. In the "Sandtrap" multiplayer map in Forge mode, first try to get as many pre-placed Fusion Coils and Plasma Batteries before starting. Place as many Fusion Coils and Plasma Batteries as possible in front of an Elephant, then drive into the pile. Then, shoot at the pile until it explodes. It will either just jump a little, stand up on the rear, or turn all the way around. When you get close, the message "Hold RB to flip... wait, what? How did you do that?" will appear. -From: Matthew Garriga

Get two Elephants to collide into each other. Have one flip the other over. When one is flipped over and you get close, the message "Hold RB to flip... wait, what? How did you do that?" will appear.

Drive the Elephant on a hill so it stays on it. Put exploding crates around the hanger. Blow up the crates with a plasma grenade. When it is flipped over and you get close, the message "Hold RB to flip... wait, what? How did you do that?" will appear. You can keep flipping it back and forth.

Breathing under water in Sierra 117 mission
At the end of the level, when the Pelican arrives after you have rescued Johnson, it destroys the two Covenant ships, one being above the water just outside of where Johnson is held. The other one is above the water in the place just before the Pelican lands. You can climb in. Once the Covenant ship is destroyed on the side where it picks you up, the debris that remains will float on the water. Jump onto it, and let it sink. After that, all you can do is just jump from one piece of debris to the other. If you touch the ground, you will die.

Monkeys with teddy bear in Sierra 117 mission
After you come into contact with the snipers in the woods, follow the left rock path to find a strange family of monkeys holding a teddy bear.

Hidden area in Tsavo Highway mission
After the part where you exit your Warthog, jump across the bridge, and kill the Brute and two Grunts that are attacking your men. Turn directly around, facing toward where you came from. Look to your left, and you will see a structure. Go up to the wall on the structure, and look to your right. There should be a pathway. Follow the path until you get on top of a bridge-like structure. There should be some dead UNSC Marines, a sniper rifle, and some other ammunition.

Crossing broken bridge with vehicles in Tsavo Highway mission
When you reach the bridge with a Warthog or other vehicle with barriers, normally you cannot cross this area. However, back in one of the buildings before the bridge is a Grav Lift. Get it, and throw it a bit before the break in the bridge, then run the Warthog or any other vehicle over it. This will make the next area much easier, especially on the Legendary difficulty setting.

Leave level boundary in Valhalla multiplayer map
Go to the ocean barrier (the side with the ocean). Then, you and another player must get a Mongoose and Wraith. Have one player drive the Mongoose into the barrier. Keep accelerating, and have the other player get into the Wraith. Drive behind the Mongoose inside the Wraith, and use the boost. You must be close for the Mongoose to go through. Once you hit it, the other player must jump out once he or she is pass the barrier.

Easy "Used Car Salesman" achievement
Go to the beginning of "The Ark" mission. Make sure you have a guest or a friend to help. Continue the mission until you reach where the crashed Pelican is found (after the first terminal). Kill the blue Brute, and grab the rocket launcher under the crashed Pelican. Continue to where the choppers are located. As you are moving, a Prowler will drive by. Ignore it because it will soon stop and abandon the Prowler leading to failure of the achievement. Another Prowler will follow. Have your guest or friend shoot it twice with a Brute Shot, then shoot at it with your rockets to get the achievement. Note: If you are by yourself, do the same thing, but instead of using a Brute Shot, throw a grenade in front of it. Then, shoot it with the rockets.

How to drive the AA wraith 101 76%
OK, this is in no way easy, so you might get frustrated alot before you get it done. 1- load up any lvl with an AA wraith(the first one on the covenant mission is easiest) 2-kill any toops around the wraith, and the guy on the gunner seat. 3- jump on top of the wraith, right on top of where the driver is. 4- melee until the hatch comes off and you can see the idiots head, then melle once more so you can see his mohawk. 5- get to a place where the option to board is not there, but you can still see the driver and are on top of the wraith. 6- hold rb down and shoot him. if you have held it, you are the proud new driver of the most powerful driveable vehicle in halo.


p.s. its guns are basically giant, repeating fuel rod guns with unimeted ammo. if you get out of the wraith, BOOM! it will blow up. if you keep messing up, then go to youtube and search halo 3 tricks by CMneir. go to #11, the AA wraith. thats what you want. look at it, then try again. if you dont ever get it, you are doing something wrong and feel fre to pummel yourself in the head with the 360 controller.

You will unlock a secret achievement by finding all 7 terminals listed:

The Ark
- Enter the first building from the start and go left into another door. You now will be in a curved corridor. On the inside is the first Terminal.

- This second Terminal does not appear until you activate the bridge to let your comrades across the gap. After activating the bridge, turn 180 degrees tol see the second Terminal.

- The third terminal is hidden in a secret room! You can find it in the third building after defeating the Scarab. First kill the group of sleeping covenant, then follow the corridor downwards. You will reach a door in front that is locked and on the left there is an open door. Go through the open door and walk straight then turn 180 degrees to find a secret room with the third Terminal.

The Covenant
- There is a Terminal on the first tower. When standing on the lift, face the access panel and turn left. Jump over to find a Terminal.

- The second terminal is accessed by Landing your Hornet on the second tower. Walk towards the entrance after landing until you see a locked door, turn 180 degrees. A Terminal should be there for you.

- There is one on the third tower as well similiar to the first tower. When standing on the lift, face the access panel and turn right. Jump over to find a Terminal.

Halo

Glitch: Forge - Repetitive Fusion Coil Dropping 67%
Want to make it look like you're whole map is being bombeb by unknown forces? Well, listen up! First, go in to edit mode and select a Fusion Coil. Hold it up about 20-30 feet in the air (or however high you think it will need to drop to explode) and keep it right there. Then have a partner begin shooting it with a Battle Rifle. As he shoots, release it. It will explode. It will then keep respawning from that point until it is moved by someone else in edit mode. To have it almost instantly respawn, change the settings on the Fusion Coils so that once one explodes, the rest immediatly respawn.

Alternate Way: If you don't have a partner around, use this technique: Put one radio tower on the ground. Then set a Fusion Coil directly on top of it. Make sure neither move. Now delete the radio tower. The Fusion Coil should now be floating with out the aid of the tower. Now run into it in edit mode. It will fall. Like the glitch above, it will continue to respawn as long as you have changed the Run-Time Minimum to the number of Fusion Coils placed on the map.

Glitch: How to be Invincible in Forge 67%
OK, have a Connection Host go as Original, not the Monitor. Then go find a weapon or have the non Connection Host in Oracle or Monitor Mode, then make a weapon for the Connection Host, count to 3 and have the Connection Host pick up the weapon, then have the Monitor pick up 1/2 - 2 secs after the Connection Host picks it up. Then don't let the Monitor let go of the weapon, have the monitor press RT [or RB, I think it's RT] to rip off the Connection Host's arms, then delete the weapon or have the Connection Host switch weapons, and the Connection Host will be invincible, but you have to shoot and melee attack once, until he doesn't get hurt, [NOTE: You are also invincible to turrets in Snowbound, and also you have to do the glitch on that level if you want to get hit by turrets, because that glitch is activated until the match is done, then you have to re-do the glitch, and no it seems that you don't need Xbox Live to do the glitch].

IWHBYD Skull 60%
Mission: The Covenant
Effect: "But the dog beat me over the fence" - Unlocks bonus dialogue throughout the game. For most, this is the last skull, so this gives you the Hayabusa Helmet as well.

To get this, get to the room where you "fight" the Prophet of Truth. Let the Arbiter kill him, turn around, and kill all the Flood here as well makes it a LOT easier. With all obstacles out of the way, you need to jump through the Halo holograms here in a specific order, listed below:

4 6 5 4 5 3 4

When you jump through the final hologram, they all light up in a sequential pattern. The Skull will be at the end waiting for you right before the energy bridge leading to Truth's corpse.

Halo 3 Secrets 59%
Grunt Birthday Party skull
Effect: Headshots on grunts cause heads to explode with confetti.
Where to find: Crow's Nest

How to find: Right after the first objective, while en route to the barracks, you will fall down onto a pipe. At the end of this pipe, look over the edge to see a small space a few feet below you. You must simply drop over and as quicly as you can, pull back to land under the floor you were just on. After that, the skull will be at the end.

Black-Eye Skull
Effect: Melee hits instantly recharges your shield.
Where to find: Crow's Nest

How to find: As soon as you start the level, head straight up to the higher level. Head toward the door with the red light, then turn around. Jump onto the racks, onto the red metal light holders, then onto the ventilation tube. The skull will spawn at the end.

Blind Skull
Description: "Shoot from the hip"
Stage: First Stage

How To Find: When you get to the area where you see the Phantom overhead (one of the marines will point it out) jump over the rocks and keep following the path on the right. When you get to the cliff there will be a rock over of the side. The skull is on the end of the rock.

Note: This skull has to be Activated before you start a Campaign map.

Iron Skull
Effect: When either player dies in Co-Op on any difficulty both players will restart at last check point or in single player if you die you restart the level.
Where to Find: Sierra 117

How to find: In the area where you rescue Sarge, behind the prison cell is a large ledge. Got to the far right side and jump on the boxes, then onto the pipes to get up on the ledge, goto the far end of the ledge, turning two corners the skull is at the far end.

Tough Luck Skull
Effect: Enemies do saving throws
Where to find: Tsavo Highway

On Tsavo Highway, about halfway through the mission (right after you are forced to walk through a large blue barrier), you will come out of a tunnel on the highway, and see a large pipeline on your left. Drop down in between the two, and run to the wall in front of you. Follow the wall all the way to where it connects with the cliff on your right, and turn to the left. There should be a few ledges--simply crouch jump from ledge to ledge, and the last one should have the "Tough Luck" skull on it.

Mythic Skull
Effect: Every enemy on the field now has double their normal amount of health.
Where to find: Halo

How to find: As soon as the mission starts walk up the hill in front of you and into the cave. Hug the right side of the cave and after a large boulder you will see a path on your right, just take the short path and it will be at the end.


Cowbell Skull
Effect: Explosive force increased (sputnik from H2)
Level: The Ark

Location: First pick up a grav lift from the small building near where you fight the scarab. Now proceed through the level until you reach the second sloping hallway (stairway), you should see some partitioned risers (platforms) halfway down. The skull is on the top level. Toss the grav-lift on the right side of the hall so it lands on the fourth little green dot from the door. Then run, jump, and use the grav-lift to propel you to the top. You should reach a ckeckpoint just as you enter the room so it you miss just try again.

Thunderstorm Skull
Mission: The Covenant
Effect: "Field promotions for everyone!" -- Upgrades enemies to their stronger versions.

After you shut down tower 1 and get access to the hornet, fly to tower 2 (the one the arbiter shut down). While walking up the stairs, go to the middle part that connects both and there should be a stair leading up to a platform where the skull is.

The 7 Terminals
The Ark:
1. Start the mission and once you enter the first building take a left into another door and now you should be in a curved corridor. On the inside is a Terminal.
2. After activating the bridge to let your comrades accross the gap, do a 180 and you should see it. (it does not open until you activate the bridge)
3. In the third building after defeating the scarab, kill the group of sleeping covenant, then follow the corridor downwards. Once you reach a door in front that is locked, immediately on the left there's an open door. Go through and walk straight off, then do a 180 to find a secret room. It is in there.

The Covenant:

1. When in the first tower standing on the lift, face the access panel and turn left. Jump over and it's right there.
2. Land your hornet on the second tower, walk towards the entrance but when you see the locked door, do a 180. Should be right in front of you.
3. When in the third tower standing on the lift, face the access panel and turn right. Jump over and it's right there.

Halo:

1. After reaching the end of the first cave, hug the right wall and you will see a building. Jump up onto the walkway and hang a left once inside. It's right there.


Fog Skull
Mission: Floodgate
Effect: "You’ll miss those eyes in the back of your head." -- Your motion sensor disappears.

As you are walking down from the anti-air gun you destroyed in the previous mission, you encounter a ramp (next to a missile launcher). Around this ramp, you hit a checkpoint. At this point, you should also hear a marine yelling, “There! Over There!”. Look up and to the right, directly at the roof of the building next to the missle launcher. There is a single flood form (not to be mistaken with the two other flood forms jumping in front of you) which is holding the skull. Kill him before he jumps, and he will drop the skull down to the ground where you can retrieve it. Too early, and the skull will get stuck on the roof though, so just time it carefully.

Famine Skull
Mission: The Ark
Effect: "Trust us. Bring a magazine." -- Dropped weapons will have very little ammo compared to normal.

When you first go into the valley to the right after the wrecked phantom, look to your left where you will see a huge boulder. Use a ghost and get to the side of the boulder that is closest to the bridge overhead. It is easy to pilot the ghost up the side of the wall using the thrust. To get the skull, pilot 2 ghosts up the wall to the top of the bridge and stack them one on top of another next to the beam where the skull is placed. Simply jump from the top of the ghosts towards the skull and land on the beam.

Tilt Skull
Mission: Cortana
Effect: "What was once resistant is now immunity" -- Enemies have different body parts that may be resistance to certain bullet types

When in the circular type room with all the flood look for a small structure piece next to two archways, jump on top if it and up on the rocks to the top left, turn left and jump up again, then do a 180 and jump to the rocks across from you. After that follow the the rock sticking out and leading up on top of of the original circular room, the skull will be in a pile of blood.

IWHBYD Skull
Mission: The Covenant
Effect: "But the dog beat me over the fence" - Unlocks bonus dialogue throughout the game. For most, this is the last skull, so this gives you the Hayabusa Helmet as well.

To get this, get to the room where you "fight" the Prophet of Truth. Let the Arbiter kill him, turn around, and kill all the Flood here as well makes it a LOT easier. With all obstacles out of the way, you need to jump through the Halo holograms here in a specific order, listed below:

4 6 5 4 5 3 4

When you jump through the final hologram, they all light up in a sequential pattern. The Skull will be at the end waiting for you right before the energy bridge leading to Truth's corpse.


Catch Skull
Effect: all enemies have 2 grenades, throw more grenades
Level: The Storm

Location: From the start, go through until you go outside again. When you go outside look straight across there is a small round building straight out there, the skull is on top. In order to get up there you can either use a warthog as a platform or grenade-jump. DO NOT destroy the wraith near the door or the skull will disappear.

Cavemen [Easter Egg] 57%
The Pelicans will crash on the Sierra 117 mission. After that, you should clear the area like you normaly do. As the area narrows as you continue there are some rocks on your left that you can jump on. Continue along a ledge thereafter. Once it heads down, you'll pass a large boulder on your left. After you do, turn around and take a look where the wall and the boulder intersect. You'll see a family of primitive cavemen! Check it out!
