There is ammo and health so be sure to watch both. the more points you score (top right) the better power-ups you get. The upgrades are health every thousand or so points and at 10000 you become invicible for a while and get a new (better) gun for a while. You get no more power-ups after 11500 points. Controls: Mouse to aim and shoot, Arrows (or W, A, S, D) to move. Kill the zombies! DO NOT DIE ! ! ! Different Music - music is from Kingoflego's Air Hockey game, thanks! LEVELS!!! Every level they get faster
