DOOM 3 Hints

How do I restore main power to the labs?

  • 1 of 6: You first need to find a control console that purports to be able to do that.
  • 2 of 6: After you leave the Delta Entryway, you'll soon come to the Delta Systems Control room.
  • 3 of 6: At the back of that room is a raised area with no less than two panels that have clickable buttons labeled "Initialize Power Systems." You're in business!
  • 4 of 6: Or not. Now you have to find some pesky Data Linker gadget that someone thoughtlessly removed.
  • 5 of 6: Return to Delta Systems Control and approach the console you used before to insert the linker.
  • 6 of 6: The linker just restores power to the immediate area. To get the elevator to level 2 working, you'll have to find and restart the reactor.
