Leaked Ubisoft image reveals Assassin's Creed: Rising Phoenix

A film? A game? A fake?

A quick blast of mystery to get Friday off the ground. All Games Beta has got hold of a murky artwork emblazoned with the phrase "Assassin's Creed: Rising Phoenix". The shot's marked "for internal use only". What could it be?

The bigger mystery, to my mind, is who or what exactly runs All Games Beta - an enigmatic, advertising-free operator that specialises in the circulation of such illicit materials. My suspicion is that it's owned by one of our dastardly competitors, and is a means of anonymously publishing content ahead of embargo. Any thoughts?
