The game, in a nutshell is a mix between "Smash T.V", "UT2k4's Invasion mode" and good ol' fashioned "Half Life". The players will be held up in a big fortified bunker (or anything really, just has to look like its been outfitted to WORK as a bunker!!! (ie city building with sandbags around it and that pokey wire stuff, etc etc), while waves of monsters (different depending on what wave it is, the waves will also be announced, ie "wave one", "wave two" etc)
