DOOM 3 Hints

How do I get to the reactor control room?

  • 1 of 4: After getting a vid message from Sergeant Kelly in another part of Delta Systems Control, head back to the main lobby (you can use the door instead of the crawlspace this time).
  • 2 of 4: Looking around for other recently unlocked doors, you'll find two of them in Delta 1 Access Lobby.
  • 3 of 4: The right one just leads to a store of supplies, so use the left one to go through a few areas and get to the Delta Service Warehouse.
  • 4 of 4: After a long, hard journey, you'll finally make it to the huge Delta Reactor Room, where you can get power restored at last.
