From One97 Communications Limited:
This is a perfect game for those times when you just feel the need to bash a horde of zombies. Shoot them or blast them, whatever is your style, but don't let them reach you or they will make a feast out of you. With three difficulty levels to suit your mood, and 4 different weapons to choose from, this game will keep you hooked.
