Zombies are all around you! They can feel the beating of your heart and the smell of your blood, so you have to strike first. Take out your gun and shoot non-stop! Your square-headed enemies will come in waves and you need to be ready for another attack, so make sure there are enough bullets in your magazine before continuing your way. Gain points, get to the end of the level and unlock new modes. One of them allows you to play as a zombie and challenges you to bite as many opponents as possible!
