Fallout 3 Hints
How can I get this door open?
1 of 10: You'll have to find and use three different security terminals.
2 of 10: Return to where you shot the first ceiling turret, then turn right and go down to the last doorway on the left.
3 of 10: Past it is the "System Operation Station 2" terminal on a corner desk.
4 of 10: Access it and choose the "Mainframe Station 2 Access Approval" option.
5 of 10: Continue down the hallway until you reach the top of some stairs.
6 of 10: Just across from those stairs is the door to the room with the "System Operation Station 1" terminal.
7 of 10: Use it and choose the same option as before (except there'll be a 1 instead of a 2 in its text), then go down the stairs.
8 of 10: Watch for another turret on the right past the second set of stairs.
9 of 10: Go through the doorway just past it and turn left to find the "System Operation Station 3" terminal on a desk.
10 of 10: After using it to grant mainframe access approval, the locked door will be unlocked.
