Zombie Survivor

Zombie Survivor works through a series of increasingly difficult levels, each one infested with swarms of the undead. Movement is smooth and responsive, which the game leans on — dodging incoming threats and lining up a precise shot are meant to be the same fluid motion rather than two separate decisions. The variety comes from the enemies themselves: as you progress you meet several zombie types, each with its own abilities and its own way of making your current tactics stop working. It is a straightforward test of two things at once, survival instinct and shooting accuracy, and the levels are structured so that neither on its own is enough to carry you very far.
