Cool :)

The whole bunker story was part of the magic vs tech campaign.

A magical summoned creature had been let loose in the bottom bunker (computer) area and taken over the computer, locked the admin area where everyone was killed, and then sent orders to the rest of the bunker, including the barracks and support craft area

The top entrance level is the only part above ground.

Unfortunately my group got the bottom and accidently set off the reactor, then failed MANY MANY times to stop it so fled and the maps lasted one session before being turned into a fine mist.
