Grab the rifle and extend your range by standing against, and shooting down waves of dead bodies. Aside of zombies, ammo and different weapons and guns, the most important problem in this 3D world of shooting is no one else but gravity itself! Fire lethal projectiles to shoot and kill your enemies, piles of brainless zombies, while learning and mastering the true force of gravity. Aim good, and good luck eliminating all zombies on sight! Use the Mouse to aim and shoot, and after the bullet is fired, use WASD to control its trajectory and movement.
