Easter eggs

Easter eggs are intentional hidden extras found within media that are often jokes or references. The Assassin's Creed series has its own Easter eggs, and many other games and media contain Easter eggs related to the series.

Carl Jung
Psychiatrist Carl Jung was referenced throughout the Assassin's Creed series:
 * The Animus was named for Jung's.
 * Women in the series such as Eve, Maria Thorpe, Maria Auditore da Firenze and Sofia Sartor (mostly wives of the male Assassins) shared their names with stages of anima development, a male's inner feminine personality.
 * Furthermore, in the Abstergo Files, it was stated that Abstergo believed their research would put an end to the debate over the existence of Jung's ness.

Jamal
Upon leaving Masyaf for the first time, one of the Assassins in the Kingdom, Jamal, could be silently assassinated with no consequences. However, openly attacking him would prompt the other Assassins to attack Altaïr Ibn-La'Ahad.

Jamal was the traitor inside the Order who, along with Masun, opened the gates for the Templar siege of Masyaf. He was originally featured as a mission target to be assassinated, but the mission was cut and he remained as a minor Easter egg.

Transformers
An arrangement of windows on certain buildings in Damascus and Acre were shaped like the torso of G1 Optimus Prime, a character from the  franchise, when in his alternate form of a truck.

Batman
Occasionally while freerunning or climbing a building, a male bystander could be heard saying "Another capering crusader." This was a reference to the superhero Batman, who used stealth, had a tendency to run on rooftops, and was sometimes referred to as the "Caped Crusader".

As well as this, Rosa greets Ezio Auditore da Firenze by saying "Why so serious?" in the memory "All Things Come to He Who Waits". This is a reference to the Joker's signature phrase from the film .

Dummy keys
In the missions "Knowledge Is Power" and "Hunting the Hunter", Ezio could loot any of the dummy targets and find keys. However, these keys had no effect at all.

Ghosts of the past
Ezio was briefly able to see a vision of his entire family. After meeting up with Niccolò Machiavelli, Ezio could return to the Palazzo Auditore and step into the center of the courtyard, where he would enter into a state similar to his Eagle Vision and be able to see the figures of his parents and all of his siblings around the palazzo. However, the vision would disappear and could not be seen again if Ezio left.

Giant squid
A giant squid could be found within the Assassin Tomb beneath Santa Maria della Visitazione. After Ezio pulled the lever lowering the swinging poles and looked into the water near the lever for about one minute, a cutscene played showing a large squid swimming by. If the lever was pulled once more and Ezio looked down again, a second cutscene showed Ezio narrowly dodging a tentacle before the squid swam away.

Mario Auditore
When Ezio first met his uncle, Mario Auditore, he said the phrase "It's-a-me! Mario!," to the young Florentine, which was a reference to the  franchise.

Motown
When throwing coins among the crowd, female bystanders would sometimes cry "Money! That's what I want!", which was a reference to the song.

Palazzo Ducale
After using the "Super jump" or "Fence glitch" to get into the Palazzo Ducale di Venezia, Ezio could access the Doge's quarters where Carlo Grimaldi assassinated the Doge. The candle that Carlo Grimaldi and Doge Mocenigo were playing under was unlit, but the chess pieces were in exactly the same position, though Ezio assassinated Grimaldi years ago.

After going into these quarters, the sky and the building turned a blood red. However, this might not have been intentional, but accidental, as scenery lightened or darkened when entering other buildings such as the Villa Auditore, to match the interior of that building. In this case, the tone was changed to orange or red to match the interior of the specific room, and so the outside scenery and sky changed to orange and red respectively.

Castle Crashers
The title of the mission "Castello Crasher" was a reference to the downloadable game, .

Grand Theft Auto
The achievement Grand Theft Dressage was a clear reference to the game series.

Machiavelli's works
Shortly after Ezio successfully enlisted the help of the three other faction guilds, Niccolò Machiavelli asked Ezio how he had managed it. Ezio simply answered that it was "", a concept about the spirit of leadership that Machiavelli was later known to have theorized. Also, at the end of Sequence 7, Machiavelli stated "I intend to write a book about you one day." to Ezio, who responded with "If you do, make it short." This was clearly a reference to Machiavelli's famously brief book, .

Finally, an achievement entitled Il Principe (English: The Prince) could be unlocked by achieving 100% synchronization for all of the memories, including the ones included within The Da Vinci Disappearance downloadable content.

Mario references
In the mission "Femme Fatale", after Ezio killed all of the guards and dragged Lucrezia Borgia towards Caterina Sforza's cell, she commented "Rescuing princesses from castles now?" This was a reference to the Super Mario Bros. games, where main protagonist Mario rescued Princess Peach from antagonist Bowser's castle.

Accompanying this, one of the achievements was entitled Principessa in Another Castello. This translated to "Princess in another castle," which was told to Mario in the original Mario games whenever he defeated Bowser's minions in their castles.

Another Mario reference was the achievement Plumber, which showed the picture of a Mario world Warp Pipe.

Metal Gear
Just before reuniting with Leonardo da Vinci, Ezio came across an factory-made cardboard box, though he looked away when Leonardo came around the corner. This may have been a reference to the  series, as the signature tactic of several protagonists from the series is to hide in a cardboard box.

A second tribute was the Raiden suit, available to those who had completed every challenge in the Animus Virtual Training Program with at least a bronze medal, a reference to how the character Raiden was trained in only virtual simulations.

Montreal
During the memory "Trojan Horse," while escorting Bartolomeo d'Alviano and his mercenaries disguised as French soldiers, a French guard asked Ezio which region of France he hailed from, to which he replied "Montréal." This was likely a reference to the location of Ubisoft Montreal, the main developers of the Assassin's Creed series.

Montreal was also the largest city in the French-speaking province of Quebec in Canada. Alternatively, it could be a reference to the birthplace of Francisco Randez – the model after whom Desmond Miles was designed.

Project Legacy
On Lucy Stillman's computer monitors in the Sanctuary, the Memories menu of Assassin's Creed: Project Legacy was displayed, set to the memories of Mario Auditore.

Red footprints
If Desmond went out to the front of the Villa Auditore and used Eagle Vision, there were a number of red footprints that could be seen which led up to the Assassins' insignia.

Various developers have stated that this was to lead the audience to where they needed to go, as some players weren't sure on what to do towards the start of the game. However, as red was supposed to signify something undesirable in Eagle Vision, it led to some confusion on the subject. As such, the developers have stated that the color of the footprints was an oversight, resolving the issue.

Hello World
In the very first sequence, Subject 16 talked to Desmond Miles about the place in the Animus that he was currently in, Animus Island, stating that it was the test world first created by Rebecca Crane to gain a feeling for the confines of the machine.

Afterwards, he proclaimed "Hello World!", which was a reference to the common test program named a Hello World project. This project was often used to familiarize a programmer with the basics of a programming language.

James Bond
The memory titled "The Spy Who Shunned Me" is a reference to the James Bond film, .

Lingering enemy
Upon reliving the first memory of Altaïr, Jamal could be seen, again viewed in red when in Eagle Vision. This first occurred in the original game, Assassin's Creed.

Monty Python
In the memory "The Brawler", after having been defeated three times in a row, the encountered citizen said "Ah... we will call it a draw, alright?" This was a reference to the movie , in which the Black Knight challenged King Arthur to a sword fight. After both his arms and legs were cut off and still refusing to give up, the Black Knight said "Alright. We'll call it a draw."

Muhammad Ali
Sometimes during fighting or after defeating guards, civilians yelled "Floats like a butterfly, stings like a scorpion!" This line also occurred when random civilians wanted to fistfight Ezio. As such, the line was a reference to the famous boxer,, who described his fighting style as "Float like a butterfly, sting like a bee."

Spider-Man
There is an achievement entitled Spider Assassin, in which Ezio had to climb the top of the Hagia Sophia in under 25 seconds. The title and achievement was a reference to the popular ' superhero Spider-Man and his ability to scale up and around buildings with incredible speed.

Superman
One title in the second stage of the Animi Training Program was "Man of Steel". This was an obvious reference to DC Comics' hero, Superman, as his nickname was known as the Man of Steel.

Alice in Wonderland
As the Grand Temple opens, Shaun Hastings says "In another moment, down went Alice after it, never once considering how in the world she was to get out again," which is a line from the chapter "Down the Rabbit Hole" from the book .

Animi Avatars
In the virtual map of the Northwest Passage used in the multiplayer, there existed two hidden paintings of Animi Avatars from former games: the Nobleman and the Vanguard. Both could be found inside of the map's biggest ship, with the first one hanging on a wall and the second one laying on the floor.

Assassin Turkey
Any time after Sequence 6, Connor could find a turkey in the Davenport Homestead if he took cover behind any corner and whistled. Following this, the turkey would appear behind Connor and follow him wherever possible. Upon the turkey's appearance, it was possible to unlock a secret through inputting the, with the directional prompts.

Inputting the code would cause Connor to feed the animal. As the turkey fed, a small Assassin hood would appear over its head.

Broken Sword
The Broken Sword Knife was a reference to the  series, which also dealt with a secret history involving Templars and Assassins.

Cool Hand Luke
Often, civilians would utter "What we have here is a failure to communicate", which is the famous line from the film . This line was appropriate in that it correctly expressed the major problem between the Americans and the British Regulars, being their mutual inability to reason or offer quarter.

Flying Machine
After completing a series of Homestead missions and retrieving stolen blueprints for the woodworker Lance O'Donnell, Connor would be given the opportunity to engage in an interactive conversation with him outside the Davenport Manor. Lance would then reveal that the blueprints contained, among other things, designs for a flying machine invented by Leonardo da Vinci centuries before.

In a clear reference to Assassin's Creed II, Connor would request to use it much as Ezio Auditore did, however, once Connor leapt off of the Homestead's cliff with the construct, he and the machine would crash into the water of the bay below. This was due to Lance and Connor not knowing how da Vinci managed to make the machine fly.

French flag
The hanging laundry in the game is arranged like the French flag.

Spyro the Dragon
When Desmond activated the mini-camera on his first mission, it made the same noise as Sparx the Dragonfly in the  series.

Predator
The trophy Predator could be earned through killing an enemy from a tree with the blowpipe, whilst using Eagle Vision. This was a reference to the  movie franchise,in which the Predator stalks its prey from tree branches with thermal vision, before killing them with a plasma cannon.

Swamp Whale
In both the original PlayStation Vita and HD editions of Assassin's Creed: Liberation, if Aveline de Grandpré climbed the lighthouse next to the Spanish fort in the Louisiana Bayou, and then climbed onto the beam jutting out on the side opposite the Viewpoint, the sound of whale song can be heard in the swamp. If Aveline continued to look out into the water nearby, she could see a whale swimming around in the swamp water, occasionally surfacing to take a breath, sticking its tail up as it dives, or even breaching the surface and splashing down. In the PlayStation Vita edition, the whale is triggered as soon as Aveline climbed atop the railing, whereas in the HD edition, Aveline must position herself on the protruding wooden beam in order to trigger the whale.

The Secret of Monkey Island
In "The Pirate Captain" memory, Edward assassinates a pirate captain called Mancomb Seepgood, which references the video game , as a pirate by the name of "Mancomb Seepgood" appears early in the story. However, judging by his claims that soon he will be the mightiest pirate in the Caribbean, it is likely he was also intended as a parody of the similarly-named, better-known protagonist of the Monkey Island franchise,.
