After long tube down w/fan... where now?
I have gone down the tube with the fan on. I went threw the mine maze and came back up into the detention center. I killed all the troopers. and in one of the rooms (where 2 s.troopers were) there is a thin window where I can see through to the glass window where the base commander was standing. but all the doors are looked and I can't get back up the tube. what am I missing?
