DOOM 3 Hints
How do I activate the service lift in PRC Maintenance?
1 of 6: If you walk up to one of its stations (Station 2 is the first one you come to) and point at its screen, it'll tell you that you need Maintenance PDA Clearance.
2 of 6: There are two other doors on the same floor as Station 2. The one to the right is locked, so try the one to the left.
3 of 6: You'll find that it leads to PRC Support Area 1 Level's upper floor. Follow it along until you get to another part of PRC Maintenance.
4 of 6: There you'll find Ron Ridge's PDA on the floor next to his body. Pick it up to get lift access.
5 of 6: NOTE: You could go back to the lift station you were at before, but it's quicker to use the nearby Station 1's console to call the lift to it.
6 of 6: NOTE: You could climb down the stairs near Station 1 and then move carefully along one side of the lift track. You can get to a couple of areas this way, but you can also get to them by riding the lift, so there's no point in risking getting zapped. Only move along the track on foot if you have to in order to get back to a lift station and recall the lift (this is sometimes necessary when you get off the lift at a certain place and can't make the jump to get back on it).
