Easter eggs

Assassin's Creed II has some few Easter Eggs, while the first Assassin's Creed had only one ( Transformers, the face of Optimus Prime in truck mode on walls) while many other games had Easter Eggs related to Assassin's Creed such as Metal Gear Solid 4, Grand Theft Auto IV and the 2008 version of Prince of Persia.

Mario

300px|left At the beginning of the third sequence, Ezio's Uncle says "It's-a-me! Mario!" which is a reference to Super Mario Bros. To further support this is Mario Auditore's Italian nationality, like Mario of Super Mario Bros.

Another reference to Nintendo's Mario is that both Mario's wear red, while the Mario's mercenaries wear green, much like Nintendo's Mario's brother, Luigi.

Giant Octopus

The Giant Octopus

A giant octopus can be found in Santa Maria Della Visitazione. The octopus appears after activating the lever that brings out the bars to swing and traverse the final chamber.

Ezio about to dodge its tentacle

To find the giant octopus you must look down the water near the lever for a minute. Once a minute or so has passed a cutscene showing a large octopus should pass by. A second cutscene can be activated if the player activates the lever and looks down again. The cutscene shows Ezio narrowly dodging the giant octopus's tentacle, then swims away.

Altaïr's Outfit

left|300px Altaïr's outfit from Assassin's Creed can be unlocked via Uplay by purchasing it for 30 points. It does not add/change any stat points for Ezio. It can also be worn in conjunction with any cape, allowing the player to wear the Altaïr outfit and still maintain 0% notoriety with the Medici or Venetian Capes.

The Bonfire of the Vanities

After downloading The Bonfire of the Vanities DLC. You are able to see a vision of your whole family. After you meet up with Niccolo, return to your old family palazzo, step into the center of the courtyard, then you will see the vision. Once you leave, the vision will disapear and you won't be able to see it again. (You won't be able to see the vision if you have completed bonfire of the vanities, so make sure you do this before you complete it.)
