The gameplay is based on first-person shooter (FPS) with a sniper rifle. The objective is to eliminate all the undead. You can also get a shotgun, a pistol, or a sniper rifle. You need to choose the weapon that you think will be the most effective in killing the undead.

The action is based on survival, so you need to make sure you can defend yourself and the civilians from the undead. If you can't, they will attack you and you will have to kill them. The game has a PVP multiplayer mode where you can compete against other players.
