Level walkthrough

After getting off the tram, head up the stairs and go left. The second door on the left goes to the female toilets which contains an opening in the ceiling. From the sink, jump up there and head through to enter a room that unlocks a Secret (1/10) containing an AutoMap and an Elite Guard (1/3):

Press the button to open the door and defeat the enemies. Continue to the room with the objective and you will find an Argent Cell (1/2) in here:

Activate the button for the objective and continue to the next area. Once the enemies are killed, you should see a reception desk where your next objective is. There is a Codex (1/4) on this:

External image

External image

Activate the button and continue to the next room. Clear the Gore Nest and enemies and then move on to the next room for some story and then take the elevator down. You will find a Codex (2/4) as you exit:

External image

External image

At the split in the path, go left to find an Elite Guard (2/3):

External image

External image

Now head to the right on the path and through some doors. Outside you will find a Gore Nest. Once you deal with that, go to the objective to lower the security field and then to the left of where that was, you should find a door that is now open. Head in here and activate the airlock and get a Secret (2/10) and find a Rune (1/2):

External image

External image

Head back through the airlock and jump across to the platform. Climb between them until you reach the top. From here look across the level and you should see some pipes that have glowing light behind them. Jump across to here and going behind the pipes will unlock a Secret (3/10) that contains mega-health:

External image

External image

From these pipes as you are looking out to where you jumped from, jump to your left and you should be able to climb behind some more pipes to enter a Secret (4/10) that contains a Collectible (Phobosguy):

External image

External image

As you exit this area, with the pipes in front of you, look to your left. You should see a Lever behind the fence. To reach this you should climb to the top of the middle section and double jump to the pipe. Hopefully you will land on one of the brackets that holds it in place. Alternatively you can climb round from the previous secret. Both these take some luck as it is easy to mess up and fall. After pulling the lever, you should double jump around the pipes and land on one of the larger brackets. Then make your way back through where the security field was and ahead of you on the left side is the Secret Door that unlocks a Secret (5/10):

External image

External image

Now head back in to the middle of the area and on the opposite side from the pipes that held secret 3 you will see a pipe you can walk along that leads to Secret (6/10) that contains an Argent Cell (2/2):

External image

External image

Now continue to the objective, along the pipe when it opens. Turn left and climb up through here. Go along the next corridor until you find a fan on the left. There is a button on the window that you can press to stop the fan. Once the fan stops, a hatch will open in there that you can climb down to reach a Secret (7/10) that contains a Field Drone (1/1):

External image

External image

Climb back out and head to the first fan room you climbed up. Activate the fan here and head up to continue along the path. When you exit the tunnel you will see a door ahead of you with BFG LABS written above it, to your left is a door that leads to a Secret (8/10) containing an Elite Guard (3/3):

External image

External image

Head through the BFG LABS door and after clearing the enemies, head to the first room on the right of the door you entered (labelled Server Room) to find a Codex (3/4):

External image

External image

Head to the next room on the right (labelled Prototype lab 01) and you should find a vent you can climb into that leads to a Secret (9/10) containing a Collectible (Pinkguy):

External image

External image

Drop down from here and now head to the room on the left of the initial door (labelled Security room). It contains the torso of a body that you can pick up. Head to the next room on the left (labelled Prototype lab 02) and find a Codex (4/4) at the back:

External image

External image

Now head to the entrance to the central room and use the button at the door. When you enter, the room will detect you shouldn't be there and try to kill you. Jump above the BFG in the centre and on to any of the platforms at the side.

When the lasers come down into the room, shoot the red bits on the bottom. After destroying some of these, the lasers will drop down and destroy the BFG container, allowing you to loot it and unlock:

Continue through the next door and along the corridor. Defeat the enemies as you go. In the next room you will find a Gore Nest. Defeat the enemies from this and then press the button to call the elevator. Defeat more enemies and then enter the elevator to exit the level.

Lazarus Labs (Level 9)

Challenges

Variety is the Spice of Death: Perform 5 different glory kills on Possessed Soldiers

  • You will find Possessed Soldiers throughout the level so I won't list specific locations. Try to remember which point part you are pointing at when you perform the glory kill, so you don't repeat them. There are more than 5 Possessed Soldiers though, so it is fine if you kill some of them incorrectly.

Thread the Needle: Kill 8 demons with a single shot

  • You will be using the BFG for this (Press cn_LT to equip it). When you find a room with enough enemies, run around a bit to gather them up. The BFG reach is far, but it is possible to wound, but not kill the bigger guys if they are too far from the shot. When you fire, make sure it is above the enemies, not at them. If it hits and enemy then they absorb the shot. There are a few good rooms to get this in. If you don't have the BFG rounds when you reach them, then just keep an eye out as you go and you should find them for one of the last rooms. You can click the following to jump to the points in the walkthrough: BFG kills 1 and BFG kills 2.

Time Well Spent: Play a game of Demon Destruction

  • This game is a terminal in one of the rooms. It doesn't immediately stand out as a game you can play so is easy to miss. You can click the following to jump to the point in the walkthrough: Demon Destruction

Level walkthrough

After leaving the elevator, go through the door and across from you on the left is a Codex (1/5):

External image

External image

In the next room you will find a Siphon Grenade on the right:

External image

External image

Continue on and drop down the elevator shaft. Kill the enemies here and in the next corridor. In the next room will be an elevator that is stuck on a body. To the right of where you enter this room is a path you can take that leads to a Secret (1/9) that leads to a mega-health:

External image

External image

After picking up the health you will drop into a room with a Gore Nest. Kill the enemies here and then continue to the next room. At the end you will climb up and have a door in front of you. Instead of continuing, turn around and jump across and follow the path until you reach a dead end. Open the vent cover here for a Secret (2/9) containing an Elite Guard (1/4) and Codex (2/5):

External image

External image

Head back to the door and go through it, at the end go through another door and you will find a Field Drone (1/1):

External image

External image

Climb up from here and enter the next door. On your right you should find a broken vent you can climb through. Follow this path to fall into the room that contains the AutoMap:

External image

External image

Now exit the room and follow the path until you reach a vent cover you can smash through. In front of you will be a Codex (3/5):

External image

External image

Continue on until you reach 2 doors. The door on the left will be locked and contains a Rune behind it. There is a vent cover in the floor in front of this door that you can open and drop into to unlock a Secret (3/9) and follow through to a Rune (1/2):

External image

External image

After completing the rune, press the button to exit through the door and continue on the path, killing enemies as you go. At the end of the path, you will come to an open vent cover that you can drop through. I found this room best to get the thread the needle challenge. I ran around all the rooms, dodging the enemies and headed into the main room. I then used the BFG to fire across the room above all the enemies to get the required 8 kills. Don't fire directly at enemies and it can stop the BFG shot. Once you have killed the enemies, you are meant to head down either of 2 sets of stairs and through a door. Instead find these stairs and between both of them is button you can press on the left side. This will open a door to a Secret (4/9) containing an Elite Guard (2/4):

External image

External image

Now head through either of the doors down the stairs and through the next big door. This room contains another large fight. You can also get the 8 kills in here for the challenge. Once you have cleared out the room, on the left side from where you entered are large stone blocks. Go behind any of these (the second from left has a Mega-Health) to find a vent you can enter that unlocks a Secret (5/9) that contains a Collectible (Eliteguy):

External image

External image

Head back into the room and open the big door with the button. At the end of the corridor, activate the button to get a loading screen before proceeding. Enter the next big room and climb up to your right look around the second floor for glass panel that has read text all over it. Next to this on the wall will be a bit sticking out that has a red light on it. You can activate this to open it up and get a Secret (6/9) that contains a Collectible (Toxicguy):

External image

External image

Continue out the door on the second floor to reach a long corridor that has a Codex (4/5) at the end and then press the button to open a door leading to the next room with an Argent Cell (1/1):

External image

External image

External image

In the left corner of where you entered is a computer screen. Activate this to play Demon Destruction for a challenge:

External image

External image

Activate the button here and head back into the room with the large stone in the middle. Activate the button under the stone and lots of enemies will enter the room. Once you have killed them all, the floor underneath the stone will open. Head down the stairs that opened up and through a church like room. Continue on through the next corridor into a room that has a hole in the middle. To the right of this hole is the Lever that opens the Secret Door. Pull this and jump into the hole for a Secret (7/9) containing an Elite Guard (3/4). Down here you will find the Secret Door also that unlocks another Secret (8/9):

External image

External image

External image

Now press the button to call down an elevator, jump on before it heads back into the ceiling and then continue on the path, drop down and head through the door. Fight some enemies here and continue along the corridor. You will enter a room with a button to press which will open 2 doors behind it. Head through either of these and kill the enemies. Then enter the room on the right and to the left of where you enter is a gap in the wall you can jump into. This will drop you down into a Secret (9/9) containing an Elite Guard (4/4) and a Rune (2/2):

External image

External image

After completing the Rune, if you haven't missed one, then you should unlock:

Continue on to the next room, and you will enter into a large fight, this is another good area for the 8 BFG kills. Once you have dealt with them, move to the objective to go up in an elevator and upon exiting, you will find a Codex (5/5):

External image

Open the next door and you will have a boss to fight. Fire rockets, guass rifle, chaingun and anything else you want. Dodging his attacks. Once he is defeated you will be transported to hell and have to fight him again. He is harder the second time, so save your BFG ammo (use 1 shot in the first stage as you can pick 1 up in the hell stage). He frequently puts walls on both sides of you and either fires rockets you need to dodge or beams of light that you either jump over or stand underneath. Once he is defeat you will unlock:

Titan's Realm (Level 10)

Challenges

Trick Shot: Kill a Lost Soul with another Lost Soul

  • The Lost souls are the floating skulls that charge at you when you get close. When you shoot one, it will fly backwards and explode. For this challenge you need to get it to explode near another lost soul. I got this by firing a rocket using the remote detonation at 2 of them whilst they were next to each other. You can jump to the walkthrough points by clicking Trick shot 1, Trick shot 2, Trick shot 3 and Trick shot 4.

Atop the Mountain: Perform a "Death from Above" glory kill on a Baron of Hell

  • The Baron of Hell is hard to get a Death from Above on. Even a double jump isn't a guarantee. So make sure you get it into the glory kill state near a ledge or stairs so you can double jump from higher than it. There are a few areas that contain the Baron of Hell. You can jump to the section of the walkthrough that I got it by clicking this.

Dominator: Kill 20 demons while using powerups

Level Walkthrough

Head through the middle of the area and you will come across a Codex (1/4):

External image

External image

Drop into the hole and fight some enemies. Then continue up all the sets of stairs and you will find a room with 4 Lost Soul skulls floating for the Trick Shot challenge. After defeating the enemies here, head underneath the electricity stones to find a button that opens a door on the lower right side leading into a Secret (1/6) containing an Elite Guard (1/2):

External image

External image

External image

Head out of here and through the gate on the left side. Fight some enemies here including more Lost Souls you can use for the Trick Shot challenge. Once they are cleared, head to the right of where you entered and along the path on the left. There is a button here on your left. Once you have pressed this, head to the left of the door you entered and there should be another enemy. Once this is defeated a gate should lower here. Now head back to where you entered and to the right of this should be a newly opened passage that unlocks a Secret (2/6) and contains a Field Drone (1/1):

External image

External image

Head through the gate that opened and you will enter an area that has a Haste powerup on the top floor that you can use for the Dominator challenge. After defeating the enemies head into the teleporter and fight the enemies here. There is a Quad Damage powerup in one of the lower paths you can use to work on the Dominator challenge. There are 2 Barons of Hell in this area for the Atop the Mountain challenge. Once they are defeated, head back to where the teleporter is, make a right from here, then up some stairs and right again. Head straight from the top and at the end, turn left to find a Secret (3/6) containing a Collectible (Keenguy):

External image

External image

Now head through the newly opened up teleporter and you will find the AutoMap:

External image

External image

In the next room, you will fight some enemies including Lost Souls you can use for the Trick Shot challenge. Then you want to make your way to the top right section of this room. You can use the gravity pad to the right of where you entered and then jump across. This is to get Secret (4/6) containing a Collectible (Silverguy):

External image

External image

Now head to the middle section of the upper level. The platform contains some armour. In here is a yellow skull. When you loot this, the ceiling will start to lower. When it gets part way down, all wall will open up on the opposite side to the yellow skull. Stand here for safety. Now drop into the next room and down the stairs to an area with some enemies and an Invincibility powerup you can use for the Dominator challenge. There is a button here and next to it is an Elite Guard (2/2):

External image

External image

After pressing the button and fight some enemies, head back to the previous room and fight some more. Then find the yellow door and look to the right for a room that contains an Argent Cell (1/1) and a Codex (2/4):

External image

External image

Now head through the yellow door and clear the area. There is a platform slamming into the ground and going back up. You need to jump on this platform to press a button at the top to open the door to the next area and the wall that hides the lever. Turn around from the door that opens and in the left corner you will find the Lever to open the Secret Door. After pulling this, you should head back up to where the yellow door was and go right. At the bottom of this slope, go right again to find the Secret Door for Secret (5/6):

External image

Head back to the area with the platform slamming into the ground and continue to the next area to find a blue skull and fight some enemies.
