Play Last Stand 2
Last Stand 2 is a crazy zombie game where hordes of zombies are determined to convert you. Your only chance of survival is to barricade yourself behind broken desk and tables, and shoot the undead before they can get through.
As you advance through this zombie game, more cool features become available to you, for example, being able to lay traps.
Good luck and try to stay alive, or at least not undead.
