Zen Studios’ tower-defense title, CastleStorm, is set to release on XBLA in April after a year of development, Joystiq reports. The game is a 2D physics-based defense puzzler (think Angry Birds) with tower defense elements – Knights defend castles from raiding Vikings, who attack with ranged weapons. Online multiplayer and co-op will be available, and players will have the ability to create their own fortresses.

No pricing has yet be announced, although with such a short time before release it’s likely that will change soon. CastleStorm is one of our most anticipated games of the year and we thought pretty highly of it when we played it at E3 last year.
