Cannon Keep

Backpack battles meets tower defense! Place and merge buildings onto the grid to grow your defenses. Expand your city's borders to increase your damage and scavenge the underground for resources. Watch your defenses cut down waves of enemies and turn the tides of combat with the commander's powerful ability. Combine turrets with various effects to maximize your city's defensive capabilities. Find your way to play by combining different buildings into your own unique strategy. Face growing hordes of enemies and take down their boss to claim a piece of the wasteland for yourself.
