When goblins move into castles, there's only one thing you can do to get rid of them. Blow up the castles. The Kinect title Wreckateer tasks you with destroying walls and towers using the power of your flailing arms. You can guide the cannonballs and use different moves to knock down these strongholds. For instance, slicing down will split the projectiles up, so you can have a sort of chain shot, demolishing the entire front of the fortress in one mighty blast.
It looks a bit like a 3D, medieval Angry Birds, but with goblins. Which makes it better, obviously. You can blow up goblin castles to your heart's content this summer on Xbox Live Arcade.
