Welcome to the world of CastleStorm, a super genre mashup of 2D physics destruction mashed with tower defense brawler! CastleStorm was born out of the fond childhood memory of building and destroying LEGO castles.
The clouds bring rumors of war…It’s Knights vs. Vikings in CastleStorm, where medieval warfare meets 2D physics-based destruction!

• Survival Co-op: Two players team up to fight off waves of enemies together! One player will control the ballista, the other controls ground…
