The Angry Birds website has a curious new area on it that seems to suggest that Green Day will have an involvement in the francise in the near future. It seems to be focused on the Facebook version of the game, but it’ll be interesting to see if this is a new path that game developers go down in the future, and it’s all rather clearly based around the band’s promo campaign for their latest album.
