DOOM 3 Hints
How do I open the locked door in Chamber 1 Access?
1 of 4: That's an easy one.
2 of 4: It says it's locked through Security Terminal 1, and it so happens that Security Station 1 is just to the right of the locked door.
3 of 4: Press "Open Locked" on the panel in the back of the security station.
4 of 4: The very same routine is used on another locked door later on near Security Terminal 2. Watch for it!
