The point of the game is to kill the Kamikazes before they invade Pearl Harbor! You kill the Kamikaze by taking away its lives by hitting it with cannonballs and unlocking abilities such as snipers, more health for Pearl Harbor, or increasing the speed and re-spawn time for the cannonballs. There are caps on each of these. Each round the Kamikazes gains more planes. You unlock abilities by buying them with the money you get from killing Kamikazes. The Bullet gives you the ability to click on the Plane to snipe it, and you have to wait between each click. The Reloading picture increases the speed and re-spawn of cannonballs. The bullet mags makes it so you can snipe faster. The health pack refills the health of Pearl Harbor. The First Aid Kit gives you 25 Pearl Harbor health every time you buy it. The dice give you a 1/9 chance of getting an ability such as double kill, double points, nuke, and max ammo. Nuke lets you click on the plane under FDR to kill everyone for triple points. Double Points gives you double the points. Double Kill depletes the Kamakazes Lives. The Final round is round 21 and you have to take 500 lives before the plane under FDR gets to Pearl Harbor.
