DOOM 3 Hints
Notes and Extras
1 of 4: The desk in the main lobby has a tiny red screen on its left side (as you face it) that will open a security hatch behind it.
2 of 4: To get into the small room with ammo in the Records Office, push a nearby box over to one of its windows and jump on the box. Make sure all the glass is out of the window, then do a jump-crouch to get inside. To get back out, use the large fallen-over computer bank and crouch-walk out the window next to it.
3 of 4: In the Teleporter Control Lab, you can use the screen to the right of McCormick to download info about the soulcube.
4 of 4: In Examination Room D2-1, press a small red panel in a dark corner to open up a health station for business.
