DOOM 3 Hints

What am I supposed to do after everything goes to H-E-double-L?

  • 1 of 5: Get O-U-double-T.
  • 2 of 5: You've accomplished the first major item of your current objective (that of finding the missing scientist), so now do the second part: return to Mars City.
  • 3 of 5: After searching Old Comm Main for spare bullets, start back the way you came.
  • 4 of 5: You're going to need to return to the main underground area via the airlocks and then head back to the security checkpoint where you started this level. The elevator will take you back up to Mars City.
  • 5 of 5: On the way back, you'll need to start honing your combat techniques and reflexes. Remember to save often, have your best weapon ready and fully loaded at all times, and all other such good tips. See the Combat Tips for more general info, plus the rest of the questions in this hint section for tips on specific non-combat obstacles.
