Your aim is to destroy all the secret weapon factories. Move left and right using LEFT and RIGHT ARROW KEYS and Press "S" KEY to jump. Hit "A" KEY to shoot your gun and "D" KEY to throw a dynamit. Hit ENTER and cheatbox will pop up. There is a hidden cheat in each level. If you finish the game, you will get all cheats. Enemies always jump over shit and mines. If you are out of ammo, you can kill them with your knife when they jump. Some enemies are too difficult to shoot, kill them with dynamite or wait until the have to reload. Have fun!
