Released on Ubisoft's Workshop site, a drawing of a man dressed in white in front of two pyramids has been released, teasing a possible connection between the Assassin's Creed series and an Egyptian setting. UbiWorkshop's Twitter account states that the picture doesn't concern AC: Brotherhood, but doesn't deny other AC-connections.
According to Joystiq.com, the drawing artists Grzegorz Domaradzki (also known as "Gabz"), Karl Kerschl, and Cameron Stewart are working together on this project. Gamespot states that this possible AC project may not be a game, but a comic book or other real-world brand investiment. One way or another, expect more news in the next few weeks.
The drawing pictures an eagle, two pyramids, a man dressed in white garments, a severed head in his left hand and a symbol of some kind where appears to be written "AC". Click the image on the right to see it in larger size.
