Back to Doom 3

When you enter head around the blood splattered corridor and take out the Chainsaw Zombie. On the right between the skeletons you’ll find the Jack Gilbert PDA.

Go through the next two doors and enter the office on the left. Use the Health Station if you need it and then open Locker 104 with the code 579.

Leave and go through the other door for the boss fight with 2 Hell Knights.

Use the BFG if you want to kill them quickly. Once they’ve been defeated you’ll be teleported to the next area.

Next: Hell
