It's the zombie apocalypse; how many days will you last? Starting on day one, you have to shoot and escape from zombies. Use the direction keys on your keyboard to move your character around town. Look for green grenades and pick them up. They will prove useful when a dozen zombies come at you at once! To shoot zombies, move the mouse to aim and then click to fire. Most zombies need to be shot multiple times to die. Try to kill them before they get to you, or they will bring your health down. Push the space bar to throw a grenade.
