Zombie City: Survival is a third-person shooter in which you play as a zombie apocalypse survivor. In this game, your mission is to help a little girl survive, but you can also help the many other characters you'll meet as you explore the city.
Zombie City: Survival has easy-to-use controls. Simply use your left thumb to move your character, the right to aim your weapon, and the three buttons on the screen to switch weapons, reload, and punch. There's no need to fire your weapon, as your character will fire automatically whenever you have a zombie in your sights.
The missions in Zombie City: Survival last about two minutes. Normally there are three different objectives to do in that time, and you'll earn a star as you complete each one. The objectives can vary greatly: you might have beat the level in a limited amount of time, kill a certain number of zombies, or get a certain number of headshots.
Overall, Zombie City: Survival is a decent third-person shooter, with good graphics, a wide variety of missions, and a vast arsenal of weapons that you can unlock as you progress through the game's story.
