Your objective in this fast paced top-down zombie shooter is to survive through the night in Story mode, fighting off wave after wave of the undead. Story mode allows you to fight co-operativley (with AI) against an ever-increasing flow of Zombies. After each wave is complete, you can purchase from a choice of 25 unique weapons, buy upgrades for your weapons, and place traps in the arena to hinder the zombie's progress. The game also has a Survival mode, where players begin with a set amount of money, and their aim is to survive for as long as possible against a never-ending chain of zombies. Use the WASD KEYS to move around the house and use YOUR MOUSE to aim and shoot. Good luck!
