DOOM 3 Hints

How can I open the office that's right across from the ACO Lift Junction?

  • 1 of 9: Trying its computer panel, you'll find that only Duncan Mathews has clearance for that office.
  • 2 of 9: So you need to find his PDA and get his clearance from it.
  • 3 of 9: Since you haven't come across it yet, search the ACO Junction Lift area.
  • 4 of 9: Mathews' body and PDA are at the east end of the lift area, up on the higher floor.
  • 5 of 9: Look around carefully for a way to get up there.
  • 6 of 9: In the SE corner of the lower floor area, you should see a small crawlway opening at floor level.
  • 7 of 9: Crouch down and enter it.
  • 8 of 9: Climb up the ladder you come to, then continue crawling until you exit onto the upper floor.
  • 9 of 9: Once you have the PDA, return to the locked office door and click on its access panel to gain entry.
