this was was on the official AC facebook page not 5 min ago, they removed it now, i clicked the link before it was removed, it showed some animus thingy video and some "activity" meter, I have no idea if it has something to do with another "big" AC game, a handheld game or a flash game, it was just up there, now it is goneAssassins, the day you have been waiting for has arrived!!! Click the link below to help reveal an exclusive look at the upcoming Assassin's Creed game!
edit, i can't belive it the thing did save in the browser history, that's what the original link linked to, just in a FB format not like that and the whole thing was animated
