1. The first 5 servo skulls will be found in this chapter. The first servo skull is located in a cathedral-like area at the beginning of the chapter. You’ll see this just after your encounter with the first group of gretchins. Just right after your encounter, head towards the right and keep on moving till you see a fern-like barricade. Hit that barricade, just after it is a hill and on the top of that hill you will find the first servo skull.

2. The next servo skull is easy to find. Just after you find the Leandros, you’ll see a monument from a distance which soon will be destroyed. Just head towards that monument, it will serve as your guide in searching for the 2nd servo skull. Keep on moving until you find the 2nd servo skull.

3. You’ll find the 3rd servo skull at the Imperial Guard Camp. After you have a fight with the Orcs and the diggers, head towards the bunker by the diggers, inside it you will find the 3rd servo skull.

4. There’s gonna be an Orc that you’ll have to take care of up there because he’ll be attacking you from above. This would be your reference point. Under that, you’ll see a room when you turn left, you’ll see the skull there.

5. The final one for this chapter can be found inside a bunker. This can be found towards the end part of the chapter.

2. The second area, before you start to fight the orks, the space marines will point out that the orks are coming out. Before you enter the door that is marked by the objective you’ll be able to see a platform where there’s also some molten tracks, go up and there you’ll locate the second.

2. The second one is when you’re going to  get out of the tunnels, at this point, use your melta gun to destroy the obstacle here and you’ll find the servo skull. This part is hard to miss because you’re definitely gonna come out of that tunnel.

#8 Journal: Inquisitor Drogan [1/10]
#3 Audio Log: Workshift 465 [5/5]

1. There are ten servo skulls that are located in the eighth chapter. Basically, at the beginning, once you drop down on this hallway, you’ll see the first servo skull which is the seventh audio log on this chapter. This is when you pass the first obstruction.

2. On the courtyard, in the guard’s quarters, before the stairs, on the first door on your right you’ll find the number four audio log in this chapter.

3. On the same area, just walk up the stairs that were ahead of you, and in another one of the rooms, on your left you’ll find the third servo skull which is the first audio log on the list.

4. So on this next section, this is where you drop a load of ground and some more fighting, once you’re in this underground area, you’ll find servo skull number four. It’s not something that you can easily miss.

5. In this building, you’ll be facing orks on the high ledges. You’ll have rocket launchers but anyway, up on this ledge before the ramp, you’ll find the servo skull number five. If you start off working your way from the bottom going up this building, it’s definitely a significant area so you’ll notice it.

6. Alright so now we have the assault pod and the rest of the logs will be located with the assault pod. Pretty much as you start off, you’ll have to go to the right and find this out grove that you’ll have to jump up to, there you’ll find the next audio log.
Note: Audio logs tend to show up whenever there’s down time with the exception of one audio log that was by the orks earlier. Most of the ones that you’ll find typically are on areas where no other monsters are around.

7. When you reach this area there is some sort of crashed rock, that we have jumped over, just to the right you’ll find the seventh one in this bombed area.

8. There are actually two ways to go to this next servo skull. First is get your way to the servo skull by leaping to it or you can use the stairway where you can enter from down under.

9. Basically, you’ll see the objective icon which indicates that there are small orks up there, you’re just gonna go straight past it. This is just a short way past the previous area, and there you’ll locate the ninth one.

10. The last is still pretty much at the same area. Instead of going up to the objective point, head along the right side, leap up above these structures, then still leap up towards the central areas. As you can see this statue, the servo skull is located right at it’s base and that’s basically all the ten servo skulls in chapter eight.

Here’s the video version of the guide:

Chapter 9: The Weapon

#3 Personal Message: Worker Nathaniel [3/5]
#2 Audio Log: Medicae Station Ventris [5/5]
#1 Battlefield Log: 2nd Lt. Mira [3/5]

1. So there are three servo skulls in this chapter. The first one is when you reach this damaged bridge section, run up to the left of that and there you’ll find the first one.

2. Servo skull number two of this chapter is pretty easy to find, you can’t miss it. As soon as a conversation starts up, you’ll be headed towards some crashed aircraft and you’ll find the second servo skull for this chapter.

3. The last servo skull is when you enter the first door to the research base and go to an outdoor section, then you’ll reach a pipes area. Once you run all around in this damaged structure, you’ll find the final servo skull. Note: This can go wrong because you can end up missing this one if you just run past it so please be aware.

Chapter 10: House of Secrets

#1 Duty Log: Transmechanic Pertronius [3/5]
#2 Duty Log: Transmechanic Pertronius [4/5]
#3 Journal: Inquisitor Drogan [2/10]

1. So once you get to this area, just turn right behind a doorway from the big room with multiple turrets. After you leave the room, destroy the two turrets in the corridor and turn right to reach it. You’ll notice that these two turrets are different because they slide back and fourth that goes along the hallway there so it’s pretty obvious when you’re at this point.

2. Now at this point, you’ll have to use the bolter to clear out all the enemies around you. You’ll notice in this room where all the test subjects are, you’ll be talking to the inquisitor about these experiments. Move to the right and you’ll see a room that’s kinda like highlighted in red and in the central room where the turret was, you’ll find the second servo skull. You’ll see some weapons too and you can swap them if you’re interested.

3. This is the part before you insert the energy source. You’ll need to run on to the side on one of the entrances where the orks were coming from and there you’ll find the third servo skull of the chapter. This particular audio log is pretty much talking about 40k, war and chaos so if you listen, you’ll understand what he really is talking about.

Here is the video version of the guide:

Chapter 11: No Skulls

Chapter 12: Dying of the Light

#2 Battlefield Audio Log: 2nd Lt Mira [5/5]

1. The first servo skull for this chapter can be located right at the beginning. You’ll  normally turn right but if you go left, you’ll see an obstruction which you can destroy. There you’ll find the skull.

2. So going on, you’ll find the room where you can find the iron halo. Right to the left of the iron halo you’ll find the next servo skull.

3. When you get to this structure here, Leandros will start to bring up a conversation. You’ll find the third servo skull at the top and when you go right inside a room.

4. Okay so now, when you’re out in this outdoor area after some chaos and some more fighting, just on the left when you move in, you’ll find the next one.

5. Unfortunately, there’s a bit of a problem with this next one because it seems to be bugged. Most probably they’ll release a new patch for this one. As you can notice, upon collecting it, it does nothing. But it’s the only servo skull that’s bugged in the game so collect it anyway.

6. The next one is located right next on the left of the plasma gun. Right on the corner of the wall.

7. Alright so when you reach this outdoor area, the servo skull is hard to miss because it’s right next to the weapons along the main path.

8. Still along the main path, DON’T enter the door if you don’t get the servo skull first. It’s right at the back part of the crates here. This boss encounter by the way is at the last part of the chapter and the Warboss is Grimskull.
Note: You can check my other guide on how to beat Grimskull on hard mode, just click here.

3. When you reach this area , there will be a conversation and you will want to check this room on the left as you’ll find the third servo skull in this chapter.

4. Alright so you’re here when the titan is already moving and the previous platform is where you activated it and you go to a door on the second platform. Check the door on the left to the middle of this area and you’ll find the final servo skull for this chapter.

3. The final servo skull is after you reach this lower level, there’s a bunch of chaos that will attack you and when you go along this hallway which is in the main path, there will be some monsters that will come and attack you. You can actually see the servo skull from here, so defeat all of them first and go get it. You’ll also see a bunch of weapons next to it.

3. The final servo skull of the game is after you encounter this chaos drone. You have to take him down first. You’ll definitely know that because this is the first one that you encounter in this chapter.
