DOOM 3 Hints

How do I get into the security office in the East Lobby?

  • 1 of 7: Checking its panel, you'll see that a security lockout is in effect due to the halon system being on.
  • 2 of 7: The nearby Bio Labs is the only other area open, so go check it out.
  • 3 of 7: You'll eventually come to a Hazardous Materials room with a malfunctioning door.
  • 4 of 7: Once past the jammed door, you have the option of entering the Security Chief's office and stealing his wonderful BFG-9000 weapon.
  • 5 of 7: Just a little ways further down is a security office that's unlocked.
  • 6 of 7: The computer console near the window has a button you can click on to deactivate the halon systems and get oxygen back into the area.
  • 7 of 7: Now you can go through the nearby door to get to the security station past it.
