Assassin's Creed Hints

Once you've beaten the game, watch the credits and for, oh, I don't know, half an hour, once the credits end and you'll appear in the place that you were at at the beginning of the game (I think, I don't have the game). It takes place in September of 2012. If you use the Hawk-eye vision on some places, you'll see some englich writing and some japanese writing. Try to decipher the code!
