An aggressive first-person shooter game featuring a post-apocalyptic world invaded by zombies is called Doom Zombie Survival. In order to kill the zombies and escape the occupation, players must use a variety of weaponry, including long-range rifles with scopes, to move across a polygon-graphics cemetery setting. Both single-player and multiplayer modes are available in the game.
How to play: To aim, use the mouse. Click left to shoot. For the menu, right-click the Scope tab.
