Visit www.flash-game.net to join the defense of the air cleaner. You are supposed to clear waves of zombies in the racing game Red Bull Kart Fighter WT. Move with arrow keys, left click to shoot or attack and press Q or E to change your weapons. Keys 1 to 7 are for different traps and use the space bar to throw grenades (number limited). The key R is for reload. Head shot kills the zombies most effectively and earns your more score. Good luck!
