umm ya zerg the object ot zm is to either get to a really high sopt and make the zombies climb while \ya shoot em off or to build a really good barricade with vending machines and couches and shit to where they can't get in or to fire wall * basiclly get 2 or 3 good ppl with powerful weapons like shotguns p90's mp5's or m4's and just build a invisable wall of firepower * the only job the zombies have is to get too and kill the humans by any means possable it's a fun game as less stress full than reg cs
