DOOM 3 Hints
What are the security codes for the locked doors in Central Processing?
1 of 6: Elizabeth McNeil's office is unlocked. Why not ask her?
2 of 6: She's not in, but her PDA is.
3 of 6: Pick it up and check the three e-mails on it.
4 of 6: The two from Michael Abrams have the info you want.
5 of 6: The Storage 07 code is 725, and the Level 3 Access code is 463.
6 of 6: TIP: Save your game before going for the elevator past the Level 3 Access door, since an archvile appears right in your face when you do. (You could use a BFG blast on him, but why not charge him with the chainsaw and saw him up the instant he materializes?)
