DOOM 3 Hints

How do I get through the Security Checkpoint?

  • 1 of 4: Once you find it (it's north of the large starting hangar area), do what the technician there tells you to do.
  • 2 of 4: When he tells you to stand on one of the red floor squares, pick one and stand on it where it says "stand here."
  • 3 of 4: Hold still there until he's done scanning you for harmful bacteria and suchlike.
  • 4 of 4: Then you can proceed through the north door to the Departure Lounge.
