DOOM 3 Hints
What's the access code for CPU Lab A?
1 of 10: Have you explored past all the unlocked doors in the Main Entrance Hall?
2 of 10: Try the one in the far NE corner of the hall that leads to CPU Security.
3 of 10: To get across the floating floor tiles in the hellish area past the door, run across them (no need to jump).
4 of 10: Once you make it to the large Security Monitoring area, there are two ways to get the code to Lab A.
5 of 10: Search all the computer banks you find for interactive panels.
6 of 10: One of them in an area to the right of the door is a security scanner. Try the various camera view options on the panel.
7 of 10: If you choose "Lab A Meeting Room," you'll see an image of a room with a large wall panel in it that clearly displays a three-digit number. Maybe that's the code!
8 of 10: The other way to get the code is to find a panel at a corner station way off on the opposite side of the room that has a button you can press to open a maintenance storage hatch.
9 of 10: Open the hatch and then find it (it's a small crawlspace at floor level) just past some stairs.
10 of 10: Crouch down to enter the hatch and find a PDA that confirms that 627 is indeed the entry code for Lab A.
