Maybe it's sabotage-maybe it's an accident. Whatever the reason, reality is getting all bent out of shape. One minute you're doing your job, pressing buttons. The next thing you know, you're staring into an alien world. Something huge with too many arms is taking a bite out of your partner's face.
Monsters are everywhere.
Madness is the order of the day. You enlist the help of traumatized scientists and trigger-happy guards to get through high security zones, sneaking and fighting your way through riuned missle silos and Cold War cafeterias, through darkened air ducts and subterranean railways where you must ride a missle transport sled straight into the jaws of slavering nightmare. So much for the cavalry. You've uprooted a bunch of nasty government secrets. You've found a portal to another world, and an alien light comes shining through.
