Judging by the fact that a trailer has been made available, it seems Wreckateer is featured in this weeks Xbox Live Arcade Spring Showcase title from Iron Galaxy and will most likely be available to buy/download tomorrow.
“Wreckateer” uses Kinect for Xbox 360 to put players in control of a massive castle-wrecking ballista. With the help of Wreck and Tinker, players can travel the land and destroy 60 castles infested with goblins using six magical projectiles.
