As part of a security force for a para-military research group, "Project Midgard", life had been pretty easy. Just sit back, watch the scientists do their work, and get paid. Well, that was before they actually succeeded at opening a gate to hell, or connecting a portal to an alien planet, or whatever the hell it is they did. To top it all off, they locked up the bunker with you outside! Now it's up to you (and your friends) to build, upgrade, and explore to hold and defend the bunker for your ticket in.
