The latest addition to the Angry Birds franchise, Angry Birds Go, is set to arrive on Windows Phone on December 11th. Rather than the traditions Angry Birds game play (parabolic based mayhem), Angry Birds Go sees gamers compete in "high-octane downhill racing" in a fully rendered 3D world. Game features include upgradeable karts, stunts, and multiple games modes. Gamers will play as characters drawn from the other Angry Birds titles, with each character having their own special power.

Angry Birds Go is an important game for Rovio as they look to expand the bird-based franchise outside of the original catapault destruction style of game play. Rovio has already tried to do this with titles like Bad Piggies, but it's clear that Angry Birds Go takes this effort to the next level.

Here's how Rovio describe the game on their blog:

And, yes! The game will be built from the ground up as a free-to-play title, with a whole host of modes and features included from the get-go. In Angry Birds Go! you can feel the rush as you fling down the track and go head-to-head in a fast and furious race to the finish line! Look out for treacherous roads, mischievous opponents and unique special powers to put the race leader behind the pack. Plus you can go from homemade soapbox car to a super-fly car by upgrading your ride. It’s all there, along with crazy stunt and air tracks, and many fun and surprising game modes. The game will be out on iOS, Android, Windows Phone 8 and BlackBerry 10.

As with Angry Birds Star Wars II, Angry Birds Go will be released simultaneously for all the major smartphone platforms.
