DOOM 3 Hints
Notes and Extras
1 of 3: In the Hazardous Materials Lift area, use the control panel near storage locker #047 to raise the nearby lift. It'll have three Z-Sec zombies, some security armor, and an explosive barrel on it. Quickly shoot the barrel to kill the zombies, then go claim their weapons and the security armor.
2 of 3: You can drop down into the pipes that go under the stairs in Coolant Monitoring to get to some hidden supplies. Also, get the grenades behind two crates in one corner -- you'll need 'em!
3 of 3: If you head down the dark red-lit hallway that branches off from Boiler Room Monitoring, be sure to save your game first and be prepared for lots of monsters to attack after you get to the far end.
