SUBJECT: Urgent message from Admiral Hackett

Commander,

There’s an Alliance researcher working on the Citadel named Dr. Garret Bryson. I need you to meet with him right away.

Dr. Bryson has uncovered important new information about Reapers that could have a direct bearing on the war. I’m officially directing you to support his efforts at the first possible opportunity. Please visit Bryson’s laboratory on the Citadel at once.

To access the DLC content, check Commander Shepard’s e-mail, located to the left of the Galaxy Map on the Normandy. After reading the e-mail, there will be a new mission available in the Journal.

Just like with the previous DLC, to access it, you have to complete it before attacking the Cerberus Headquarters, which is the “point of no return” in Mass Effect 3.

After reading the e-mail from Alliance Command, this will become a new objective under Mission Summary in your Journal. Go to the Galaxy Map and choose to travel to the Citadel. However, there will be a different option this time than before.

Instead of just having the option to dock at the Citadel, there will be two options. One will be the aforementioned usual choice, and the other will allow you to go directly to Dr. Bryson’s lab. Choose this option and then watch the cut-scenes unfold.

During the cut-scenes, there were will be two separate QTE opportunities. The first one is a Paragon QTE that you can activate using LT and the second one is a Renegade QTE that you can activate using RT. You can choose to do these or not, it’s irrelevant. After which, continue watching the scenes and respond to the dialogue pop-ups as prompted.

Following the cut-scenes, you will finally have control of Shepard again, if only momentarily. Report in to the Alliance Command, and then your next goal is to find an audio log that the assistant was rambling on about.

The audio log will be found directly on the desk in front of you. Approach it and press A. Listen to the audio log and watch the cut-scene, responding to dialogue options in any manner that you wish, and now your new goal is to figure out where they were searching for Leviathan by investigating the lab.

Examine the specialized Galaxy Map in the room. You need to narrow it down significantly, so start looking around. On the wall in this room are a bunch of photos of seemingly random people. Examine the computer consoles and video logs to discover that it is actually photos of people that are “black out killers”, like what has just happened with Bryson. EDI will then filter the search on the Galaxy Map to planets that have experienced these types of killings.

I recommend walking around in the outside area of his lab as well. There you can find various upgrades for weapons that were once exclusive to the Mass Effect 3 multiplayer mode, now mad available for use in the single-player game. Enjoy.

At any rate, in the other room of the lab, there is much more to examine. On the far wall, you can find more photos and a light switch. Turn on the light, which will reveal an elaborate tracking of the Leviathan sightings and evidence. Examine this with EDI. Then to the left of that will be meteorites. Examine the meteorites, then use the scope to discover trace amounts of Element Zero within the rocks. This will help EDI to narrow it down even further.

Now turn around and examine all the logs on the center table. After watching the video logs, activate the console and learn new theories about everyone’s favorite creepy crawly race of alien bugs. EDI will then narrow it down even more. Then finally examine the desk in the corner. There will be encrypted data there, as evidenced by the logs. The clue you get is that the code to access the data is “close to [Bryson's] heart”.

Go back to the table where you learned about the bugs, and underneath an object there will be a crudely drawn picture by Bryson’s daughter. EDI will analyze the picture and find nothing useful. Go up the stairs and then listen to the audio log on the dresser. Then examine the picture on the end-table in the corner. EDI will analyze this as well, which will give you the access codes.

Go back to the data pad and access the data. Then return to the main Galaxy Map. You can pinpoint the exact planet by activating and deactivating the various clues. You can play around with this if you wish, but all you need to do is activate the Leviathan clues, the alien sighting tracking, the Element Zero traces, and this will pinpoint the exact location for the Normandy, and net you an achievement.

4. Leviathan: Find Garneau
- – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - -
Once you’ve pinpointed the location, or even narrowed it down some, return to the Normandy. To do this, exit the lab and go outside. There will be a ship waiting with its doors wide open. Press A to get on it and return to the Normandy.

Back on the Normandy, go to the Galaxy Map. The place where you find to scan for Dr. Garneau is the Caleston Rift. If you are playing this DLC at a late point in the game, likely right before the attack on Cerberus HQ, then there will be a great Reaper presence here, which will make scanning the cluster a little bit more difficult.

Balor will be the solar system that you visit inside the Caleston Rift right at the start. Exit this area by flying to one of the green arrows in the circle surrounding the system. Dr. Garneau needs to be searched for in the Aysur system. You will need at least 320 fuel to make the trek from Balor to Aysur, so be sure to fuel up before embarking on this journey with the Normandy.

Once in Aysur, look for a planet in the asteroid circle. Scan near this planet with the left trigger, and then examine it. This will be Mahavid, where Dr. Garneau is located. Land on it. Choose your squad, choose their loadout, and upgrade them if they have any skill points that they can spend.

5. Mahavid: Leviathan
- – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - -
Take the elevator down. There will be a Brute and two Marauders down here. Kill the two Marauders first, and then focus on the Brute. Up the stairs, you will find another Brute. Kill him, and then bypass the lock on the door. Move forward and go through the next door by pressing A.

Watch the cut-scene unfold with the creepy people of Mahavid. Speak with them about Dr. Garneau, but they won’t be of much help. Now you have to figure out where Dr. Garneau is. Talking with the researchers and miners down here will yield nothing interest, but there are datapads that you can read for more info as well as credits.

If you examine the elevator in the room, you’ll discover it’s broken. Not to far from the elevator will be a downed repair drone terminal. Hack into the repair drone and then wait for it to come out. Follow the holographic drone to the elevator and wait for the drone to fix it.

Take the elevator up. On the next floor, you need to gather more information about Dr. Garneau. Once again, speaking with the people will be a hopeless endeavor. Instead, you need to focus on reading the datapads and figuring out where Garneau is. Explore this mining laboratory until you find a door that you’ll need to bypass. Bypass the door and read the datapad inside. Check the back of the room to find an upgrade for SMGs.

The game will then point you to the security terminal that you need to access. Go to the terminal and activate it. This will explain that the med bay needs an access code as well, and there’s someone that was put there for getting into an altercation in the mines. Go through the door marked Sector 4 to find the medical bay, and approach the door. Press A, and then one of your squadmates will offer the code to get through.

Move through the med bay, and take the first left. Open the medical kit on the ground, and then approach the window on the left. There will be a body laying on the other side of the window and that can be examined with the press of the A button. Watch the scene and go through the dialogue options.

Chase Garneau into the next hall and then go through the door. You’ll find a ladder, so climb it up. A loading screen will occur, and then you will be in an open area, still chasing after Garneau. However, this place will be crawling with Husks. Kill them all, and then leap across the gap at the end of the area. Climb up the ledges, drop down, and then go around the corner to see Garneau making a break for it toward the mines.

You’ll then be swarmed with Marauders and Ravagers. Take cover and take them all out. They will start flanking you from the left, so kill those guys as well. A couple of Banshees will show up next, so do your best to take them out and don’t let them get too close. When they’re all dead, make a break for the mines that Garneau ran to.

If you try to open the door, you will discover that it is broken. There are three devices that need fixed in order for the door to open. A repair drone will start making its way to the first device. Walk with it and stay in its field, otherwise it won’t continue to the next machine. Wait for the first machine to be fixed, and defend the drone from the enemies that show up. Then move on to the second machine, killing the various enemies as the drone fixes up the second machine. As you go toward the third machine, there will be Banshees to deal with, but the third machine is in a very well-covered position that will make it somewhat easier to deal with than the Banshees from before.

With all three machines fixed, return to the door and enter to go into the mines. Garneau will be found lying next to the artifact, with Husks crawling around all over the place. Go through the dialogue and watch the scenes. When the scenes conclude, an achievement will unlock, and you will once again regain control of Commander Shepard aboard the Normandy.

Go to the Galaxy Map and then fly back to the system with the Mass Relay. Use the Mass Relay to fly back to the Citadel. Once again, there will be a second option of going directly to Bryson’s Lab. Choose this option once docked at the Citadel.

Back at the lab, it’s time to gather more information. The Leviathan artifact will be shielded, allowing Shepard and EDI to freely roam around the lab without worry of being taken under control of Leviathan like with what happened to Bryson’s assistant. On the desk in the first room, there is a strange husk head sitting on the table. On either side of it, are new objects that can be examined for more information.

Move into the second room of the lab, and examine the terminals here. EDI will discover that Bryson as received a new message on his personal comm terminal upstairs. Go up the stairs and then check his comm terminal. It is on top of the dresser next to Bryson’s bed. Watch the video message left by Bryson’s daughter, revealing that she is in the Pylos Nebula.

7. Leviathan: Find Ann Bryson

At Bryson’s lab, it’s now time to find more clues to narrow down exactly where she is in the Pylos Nebula. The first clues you can gather are in the second room of the lab, and that is figuring out which ship she took on the expedition.

On the big desk near the Sovereign fragment is a large screen, with a small device to the left of it. Interact with the device to turn on the screen, and you can use the device to flip through the different ship images. Now examine the datapad on the desk near the Element Zero rocks to narrow it down that Bryson’s daughter Ann took the Icarus ship. Return to the screen and click on the image of Icarus so EDI can better filter your search. Check out the other terminals and datapads in the second room for even more info.

Now go into the first room of the lab. There is a locker there that was mentioned in one of the datapads in the first room. Examine it, and you’ll find out that it’s locked. Go to the island counter with the freaky husk head on top of it, and examine the drawer at the far end. Open the drawer, the interact with the datapad inside. Go back to the locker and open it. Grab the leftover equipment, and figure out what equipment is missing, and what equipment Ann left behind.

This will narrow down the search enough to pinpoint the exact system that she’s in. Use the Galaxy Map in the lab to narrow it down, and then get back into the cruiser and return to the Normandy. On the Normandy, use the Galaxy Map to travel to the Pylos Nebula, on the north side of the map. It will be flashing, but there won’t be any text over it.

Fly out of the first system you’re in, and move to Zaherin, the system marked as the dig site. Fly to it, and then scan the planet on the second ring. This planet is called Namakli, and it is the planet that Ann’s dig site is. Use the scanner to find her exact location on the planet, and launch a probe once you do. After that, you are able to land on the planet and continue the search for Ann!

8. Namakli: Leviathan
- – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – – - – - – - – - – - – - – - – - – - – -
Upon setting down on Namakli, move forward. Ignore the Harvesters and just keep moving forward from area to area. Set-pieces will change the environment, such as a room blowing up and forcing you to walk across its roof, but nothing major happens and there are no enemies to fight until a couple of Husks show up to give you a headache.

Eventually, you will come to a dead end. The direct path to the elevator will be destroyed. So, turn around and climb the ladder on the last building you moved through. At the top, move to the cliff side and jump across. The bridge will be out, and upon examining the bridge controls, you’ll discover that they’re broken as well!

One of your squad members will start fixing the bridge controls, and Husks will show up. Equip a shotgun and go to town on them. When the Husks are defeated, a Banshee will join the fight, but only one of them. Kill the Banshee, and then the bridge will extend. Go across the bridge and work your way to the elevator. The elevator will be blocked, unfortunately, so Ann will bypass the door next to it. Go through the door, and then hang a left.

Quickly get behind cover as there is a sniper in the distance. Pick him off from your current location, but there will be another one, so be sure to kill that one, too. Cannibals and the like will rush your position, but it shouldn’t be anything you can’t handle. Once they’re dead, work your way up to the next ladder you need to climb, killing the Swarmers as they get in your way.

Continue to work your way toward the elevator, killing the enemies as they show up, and ignoring the Harvesters. It’s just a waste of ammo to deal with them at this point. You will go through a couple of rooms with medical kits on the ground, so be sure to loot them as you move toward the elevator. It’s basically just a linear, straight-shot to it. Once you arrive, call it, and then get on it and use its controls to reach Ann, and speak with her.

Following the scenes, Cortez will start bringing a shuttle around. Take cover and start taking out the enemies using a combination of your abilities as usual. A Harvester will swoop down, and this is the time to focus on the Harvester. Make sure you’re behind cover, and the Harvester will have a very difficult time even getting a single attack in. Keep laying into the Harvester until it dies, and then Cortez will have brought the shuttle and docked it. Keep killing the enemies until you get to the shuttle and then board the shuttle. Speak with Ann on the shuttle.

9. Citadel: Leviathan (3)

Exit the Pylos Nebula by going to the Nariph system and using the Mass Relay there to return to Citadel space. As usual, dock at the Citadel and then choose option B, Bryson’s Lab.

After speaking with Ann the first time, go downstairs and speak with her near the Sovereign fragment. Then follow her to the Rachni terminal and speak with her again. Then follow her into the first room of Bryson’s lab, and speak with her when she nears the Galaxy Map. Go through the conversation choices, but it will all end with Ann volunteering herself to be taken under Leviathan’s control so that they can track his signal.

During this process, James will repeatedly try to put the shields back up on the artifact to protect Ann. Every time that you stop him, which you do by pressing RT during the scenes, this is Renegade behavior. If you don’t like playing as a Renegade, just let him put the shields up the first time and I’ll tell you exactly where to go. Otherwise, just keep speaking with Leviathan through Ann and watch as she gets worse and worse.

Depending on when you let James put up the shield will determine how narrowed the search is, but I will tell you exactly where to go. On the north side of the Galaxy Map on the Normandy is a galaxy called Sigurd’s Cradle. Exit the initial system with the Mass Relay, and fly to the East to the Psi Tophet system. Scan the blue planet on the first ring around that star called 2181 Despoina. Launch a probe, and then land there.

10. Despoina: Leviathan
- – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - – - -
After your rocky landing, start exploring this docking area while Cortez does repairs. Examine all the highlighted areas, including the large mech suit, and tap on the right analog stick to check out the crashed ships sticking out of the water in the distance. Move as far as you can away from the ship, and then move as close as you can to the water. That’s when you can click on the right analog stick and look up to see Reapers moving in on your position!

Sprint all the way back to the ship and take cover. Reaper soldiers like Cannibals will join the fight, so push through and kill them all. Brutes will also show up, but if you get inside one of the few tents that are set up around this docking area, they can’t even hit you. Better yet, instruct your squadmates to go into one of these tents, and then get the Brutes near them. The Brutes will focus all their efforts on them, which allows you to just blast away until they are dead.

Once Cortez has the ship up and running, he’ll fly around and help you by killing enemies. However, the ship will go back down on the opposite end of the barge. Sprint to Cortez, and get behind cover with him, helping him kill the Cannibals and Marauders. Speak with Cortez once the coast is clear and develop the plan to get Leviathan wit him.

Cortez will give you a power cell. Pick it up with the A button. Then move to one of the two power switches. Press A to use up the power cell, then go back and get another power cell. Ignore the enemies as much as possible — your squadmates should be able to handle them efficiently, but if they get in the way, don’t hesitate to take them out. Keep going back to Cortez and powering the same switch over and over until reaches 100%.

With that, the doors will open and reveal the mech. Get inside the mech and start slaughtering the Reaper enemies. A few Brutes will attack at once. RT fires cannons, LT fires missiles, and B is melee attacks. Melee is especially effective against Brutes, as well as missiles. Kill the Husks, Cannibals, Brutes, and whatever until they are all dead, and then return to Cortez and go through the dialogue and watch the cut-scenes (and loading screens).

In the mech, deep underwater, move to the right. The mech suit will fire flares automatically. There will be a dip in the ground, so move off the side of the cliff and fall down farther. Keep moving and then fall down again, landing on the somewhat thin strip of land. Keep moving then until you speak with Leviathan. Go through the dialogue and cut-scenes, report to Hackett, and that’s that.
