Ubisoft is working on a strange new game going by the name Hero. This info has come to light as a result of some sleuthing on the part of one of Kotaku's columnists, Superannuation.
Though the initial storyboards have since been taken down, All Games Beta managed to upload the videos to Daily Motion. As of right now, they are still available for viewing and can be seen below. (Update: the videos have been taken down from Daily Motion. However, the video has been re-uploaded to YouTube)
What kind of a game could this be? A new MMO? A time traveling action title? Leave your best guess in the comments, because it is just as good as ours (unless you work for Ubisoft, in which case it is a much better guess).
