The concept of Battle Castles seems simple enough. Defend your castle against cannonball attack from pirate ships trying to breach the wall. After the first few levels, things start to get crazy as the pirates get armored submarine type boats, their cannonball attacks get bigger, they have crews tunnel underground toward your castle to collapse the wall and an increasing number of ships come to pillage your castle. A quick mouse finger and careful aim will keep the marauders at bay. Between levels, you can repair your walls, add guns and renew your defenses in preparation for the next wave of invaders. This is arcade action at its best; simple concept with high energy fun.
