Zen Studios, the team behind Pinball FX 2 (and its many offshoots, including the recent Star Wars Pinball), has released their next game on the Xbox Live Arcade: CastleStorm. For 800 Microsoft Points ($10) you can jump into the eternal war between vikings and knights (just go with it) in this 2D physics-based battler:
It’s Knights vs. Vikings in CastleStorm, where medieval warfare meets 2D physics-based destruction! Controlling the battle in real time, players will harness the power of medieval artillery, manage a fearsome ground attack, and cast powerful spells! CastleStorm features a story-driven solo campaign, a custom castle editor, online multiplayer, co-op modes, and more. Building castles and knocking them down has never been so much fun!
