They Are Coming: Zombie Shooting & Defense Android Game Description:
The levels of the game are designed as small pseudo 3D locations, in which there is a barricade, the player's character and waves of zombies that attack the barricade. The player's task is to keep the zombies from getting through the barricade. To do this he has an arsenal of firearms and cold weapons, as well as the ability to set traps.
The shooter is quite bloody, with enemies blown to pieces and the small battlefield left stacked with defeated zombies. The ragdoll physics only enhances these bloody effects, but the pixel graphics make them not that scary.
