Rovio is planning to debut a new game in its Angry Birds series, entitled Angry Birds Go. Created in partnership with RedBull, the game was first teased in mid-June with a website that featured a bird dashing down a pathway.
The specific game mechanics are unclear, but it does appear that players will race karts against each other. While the video teaser does not mention a specific release date, it does say "All will be revealed soon!"
