Turn around and exit the teleportation chamber. Grab this medkit in the neighboring corridor. The door ahead requires a keycard that you don't yet have. Don't freak when the pipe starts steaming. Up ahead this flaming zombie attacks. Note the shells by his foot. An armor vest is in the room behind him, but is blocked by fire. Continue through the door on the right.

Here's the keycard that you need, right next to the headless zombie.

Be careful on your way back, as two Imps will pop out from a false wall opposite this door. Best to ready your Plasma Gun, step forward just enough to trigger the Imps, then back into the doorway.

Doom 3 Walkthrough - Doom 3 869
Doom 3 Walkthrough - Doom 3 869

Your first Archvile spawns above. He will summon Imps as seen here. Killing the Imps is merely hacking at the weeds. The Archvile is the root. Defeat him first. The rocket launcher does it right quick.

Poor guy. Show the Imp that did this some justice, then take Jacob Stemmons' PDA to learn the code 371 for an upcoming storage locker. Climb the ladder to find supplies including armor, cells and a medkit.

This next bend is very difficult. Three Imps are triggered here, so be prepared. Note the cells on the right. Plus, a trap is set for you to the left of the Imp visible here. A plasma gun will trigger the floor to drop when you grab it.

Doom 3 Walkthrough - Doom 3 892
Doom 3 Walkthrough - Doom 3 892
