Defending your castle is simpler than history might have you believe. Simply position your mouse over an enemy troop and use the left-mouse button to pick him up. Make a throwing motion with the mouse, releasing the button to fling your unfortunate victim through the air.

Alpha Force A solid shooter in the vein of the classic side scroller shooters of the past. Collect power ups, smart bombs and destroy the bosses. The game has lots of shooting, lots of dodging and a huge line up of power packs. All I can say its a 5 levels of frantic action as you battle to save the earth.
