Zombies, Zombies Everywhere!

In Zombies, Zombies Everywhere!, the player controls a weapon (actually only the crosshairs) and kills endless zombies which approach from the back of the screen. Ammo is unlimited, but the gun needs to be reloaded from time to time. When the zombies manage to come too near, they hurt the player and the life energy drops. The game is lost when health reached zero. There is an online high-score list.
