Access Lift (Apocalypse)
The main entry point for your base.
Every base has one in a predetermined position and is used both to bring items into and to get items out of the base. Heavy-duty anti-grav fields ensure that even the heaviest items and equipment are lowered and lifted safely.
During base attacks, this is where most enemies will enter unless they are using a hangar, and this is also where your troops or scientists can flee the battle.
