You are controlling an alien space craft to kill little army men beneath you. You use your mouse to move the ship back and forth and need to click to shoot at the men below you. You get more points for the more men you kill and the longer you are able to play. You can lengthen game play by shooting the barrels that appear. Some will give you more time on the clock and some will explode allowing you to kill several army men at one time. Your ammo will run out at times but it will take only a moment for it to reload.
