It appears details for the next Assassin’s Creed has been accidentally revealed by a retailer.

A picture has been taken of a GameStop advert for the game Assassin’s Creed Brotherhood to persuade shoppers to pre-order.

We’re sure there are many red faces at GameStop right now, and if you need any more proof that it is genuine, Ubisoft have themselves confirmed the authenticity.

They go on to say that we can expect more details on the game next week.

But not only does the advert reveal the game title, it also confirms a Fall 2010 release which will be around only a year since AC 2 arrived on the scene.

Little is known about the title already except that it will again follow Ezio, but this time in Rome, and the game will feature multiplayer.

In other Assassin’s Creed news, the complete edition of the last game has also been leaked, this time by ShopTo!
