When Rovio revealed its plan for Angry Birds Go! back in August, the direction of the game wasn’t clear. The gameplay trailer confirms that the game is less an endless running game than a kart racing game that sends you careening down dangerous hills.

The trailer below details some of the features we can expect when Angry Birds Go! releases on December 11. The colorful downhill racing game will have special powers, upgradable carts, and be free-to-play. Angry Birds Go! is coming to iOS, Android, Windows Phone 8, and Blackberry 10.
