Defense Your Castles

Are you ready for a tower defense fight?  Good and you better be if you are going to step up and take the challenge that you face in the Defense Your Castles tower defense game.  You castle will be facing an attack from some bad dudes and its up to you to use your shooting skills to defend it and shoot the enemy before they storm your castle and tear it down.  You only have a limited number of bullets in your gun so you will need to make every shot count if you want to shoot the required number of bad guys and complete each mission.
