The maintenance safety video on the left is a must-see. Read Nick Sadowayj's PDA to learn the code 483 for a storage cabinet by the monorail airlock.

Backtrack to this position. The door on the left returns you to this room and should only get you some armor and clips you may have left behind. Plus, you'll have to fight three Imps and a maggot.

Doom 3 Walkthrough - Doom 3 629

Another Maggot and this Imp are ahead -- but the important thing to note is on the shelf below - the rocket launcher! Two medkits are beneath, and more rockets are in an alcove to the right. Continue through a door on the left.

Doom 3 Walkthrough - Doom 3 631

A Revenant is firing at you from above - a great time to try out your shiny new rocket launcher! Note the two oxygen tanks visible here. The door far-left is non-functional. Instead, approach that bunker straight ahead.

Doom 3 Walkthrough - Doom 3 632
Doom 3 Walkthrough - Doom 3 632
