It says that it has low power, so it's in standby mode. I've done fucking EVERYTHING in the level, restored power to the reactor, got it spinning, gotten the power coupling dealies, and went back to the main lobby to get on the elevatory, only the damn elevator won't work. I'm in the Delta labs, right after I got off teh monorail. Okay, so this is the only time I've been really stuck in Doom 3.
