Easter eggs

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

Carl Jung
Psychologist 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.

Jamal
In Assassin's Creed, 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 that, 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 seen on certain buildings formed the torso of Optimus Prime, in his vehicle form (a truck) from the Transformers franchise, which could be found in Damascus.

Batman
Occasionally in Assassin's Creed II, while freerunning or climbing a building, a male bystander could be heard saying "Another capering crusader." This was a reference to the DC Comics superhero Batman, who used stealth and had a tendency to run on rooftops. As well as this, Batman was sometimes referred to as the "Caped Crusader".

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

Ghosts of the past
thumb|200px|Ghosts of the Past By downloading the Bonfire of the Vanities downloadable content, 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. To find the giant squid, Ezio must pull the lever that activated the swinging poles for progressing further into the tomb, but look down into the water near to the lever for one minute instead.

Once a minute or so had passed, a cutscene played, which showed a large squid swimming by. A second cutscene could then be activated if the lever was pulled once more and Ezio looked down again. Following this, the cutscene showed Ezio narrowly dodging one of the squid's tentacles before it swam away.

Mario Auditore
200px|thumb|Mario greeting Ezio 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 amongst the crowd, female bystanders would sometimes cry "", which was a reference to the classic song.

Palazzo Ducale
thumb|200px|Palazzo Ducale easter egg 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.

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.

Castle Crashers
The first memory in Assassin's Creed: Brotherhood near to the Castel Sant'Angelo was called "Castello Crasher." This was a reference to the PlayStation 3 and Xbox 360 downloadable game, Castle Crashers.

Grand Theft Auto
The achievement Grand Theft Dressage was a clear reference to the Grand Theft Auto 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 famous (and brief) book, "."

Finally, an achievement entitled Il Principe (which translated to "The Prince") could be unlocked by achieving 100% synchronization for all of the memories in Brotherhood, 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 Mario rescued Princess Peach from Bowser's castle.

Accompanying this, one of the Brotherhood 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 Solid
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 was a reference to the Metal Gear Solid series, as the signature stealth move of Solid Snake (the series' protagonist) was to hide in a box or crate.

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 Auditore as to 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.

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

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.

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 fight and, after both his arms and legs were cut off, 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 was 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  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 ' hero, , as his nickname was known as the Man of Steel.

James Bond
The second memory of Sequence 7 in Revelations is titled "The Spy Who Shunned Me." This is a reference to the James Bond film, "The Spy Who Loved Me."

Alice in Wonderland
As the Grand Temple opens, Shaun 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 .

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 Continentals and British Regulars, being their inability to reason or offer quarter.

The Dark Knight Rises
When Connor encountered Charles Lee in the first memory of Sequence 12, Lee mentioned that he was going to burn down the Davenport Homestead and destroy Connor's village, and "When (Connor)'s seen all his life's work brought to ruin. Only then will I allow him to die."

This paralleled the lines spoken by Bane to Bruce Wayne in The Dark Knight Rises, "And then, when it is done, and Gotham is ashes... then you have my permission to die." The circumstances were similar but due to the time between the movie and the release of Assassin's Creed III, the lines were likely an unintentional allusion.

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

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.

Xbox 360: Up, Up, Down, Down, Left, Right, Left, Right, B, A.

PS3: Up, Up, Down, Down, Left, Right, Left, Right, O, X.

PC: 2, 2, 4, 4, 1, 3, 1, 3, E, Space.

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

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.

Animi Avatars
In the virtual map of Northwest Passage, 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.

Broken Sword (game series)
The "Broken Sword" Knife was a reference to the, which also dealt with a secret history involving Templars and the Hashashin.

The Last of the Mohicans
The Gunstock Club was an exact replica of the club used by the character Chingachgook in the 1992 version of .

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

Assassin's Creed III: Liberation
There was a trophy in Assassin's Creed III: Liberation named "Predator", which could be earned through killing an enemy from a tree with the blowpipe, whilst using Eagle Vision.

This was a reference to the Predator movie franchise, where the Predator stalked its prey with thermal imaging, and then killed them with a gun from the trees.

Assassin's Creed IV: Black Flag
Throughout Abstergo Entertainment's Montreal building, several real-world games, books and other Assassin's Creed media can be found.

Accompanying this, there was a glass case in Olivier's office containing several weapons, including a silver handled Syrian Sabre, Maria Auditore da Firenze's dagger, and four replicas of the double-barreled shotgun from Red Steel 2, another Ubisoft title.

There's a pirate hunter ship called Thriller Bark. This could be a reference to a ship of the same name in the One Piece anime.

One mission is named "Vainglorious Bastards", a reference to the movie "".

In The Pirate Captain memory, Edward assassinates a pirate captain called Mancomb Seepgood. In the video game , a pirate by the name of Mancomb Seepgood appears early in the story. In addition, the name is notably similar to that of the game's protagonist, Guybrush Threepwood. Furthermore, Mancomb's name in The Secret of Monkey Island is meant to reflect Guybrush's.

Prince of Persia
In the first tome of the novel, during Desmond's flashback, the, the main protagonist of the famous Ubisoft series, appeared on the screen of the arcade game monitor at the "L'Horizon" bar.

Assassin's Creed in other media

It also mentioned the password "122112", a reference to the solar flare date in Desmond's storyline, and an Abstergo Industries logo could be found on several of the walls.

As well as this, earlier in the game, Jason mentions "leap of faith" before jumping into a pool of water, reminiscent of the Leap of Faith from the Assassin's Creed games. Also, at the beginning of the game, they quote "In another moment, down went Alice after it, never once considering how in the world she was to get out again" from Alice in Wonderland, very similar to how Shaun Hastings quoted the phrase in Assassin's Creed III. However, they continue quoting dialogues from the book throughout the game.

Moreover, the requirement for the achievement was the completion of nine assassination missions, which paralleled the first Assassin's Creed game, in which Altaïr Ibn-La'Ahad was tasked by Al Mualim to kill nine Templars in exchange for his reinstatement as a Master Assassin.

inFAMOUS 2
Located in the fictional city of New Marais, several cinemas and theaters in inFAMOUS 2 featured movie titles that were direct puns to popular video game names. Among the movie titles was "Assassin's Need (Love Too)", a parody on Assassin's Creed. These cinemas were located in the very first district of the city. Also, one of the negative karmic missions available in the game was named "Assassin's Greed", another play on the Assassin's Creed name.

Another Easter egg found in the game's downloadable content, inFamous 2: Festival of Blood, could be seen again on the cinemas' featured movie titles. The new parody title was "Assassin's Bleed", which was also a reference to the download content's central theme of vampires.

LittleBigPlanet
As a part of their promotion for Assassin's Creed II, Ubisoft released Ezio's Assassin costume as a downloadable outfit for the PlayStation 3 exclusive  on 8 December 2009.

On the day that Revelations was released, LittleBigPlanet released a new costume of Ezio, featuring Sackboy in the robes that Ezio started out with in the game, as well as his beard.

Metal Gear Solid series
On April Fools' Day 2008, it was revealed that an Altaïr costume for Old Snake could be unlocked in the game Metal Gear Solid 4: Guns of the Patriots. Hideo Kojima, one of the game's creators, later announced that it was not a joke, and that the costume could really be unlocked if the player did "something special." In order to unlock the costume, the player must have either acquired the "Assassin Emblem" (a nod to the games' emblem) or input a password in the "Extras" section. Specifically, the password was revealed to be aottrykmyn.

The costume could be used as an alternative disguise early in-game and worked exactly like the Middle East Militia costume. Unlike Altaïr's robes, the Militia costume was lost early in-game, prompting the player to find another set of the disguise, and could cause the Middle Eastern faction to be friendly to the player as opposed to having to work to gain their trust. When the costume was worn, Old Snake's idle stance, without any weapons equipped, is exactly like Altaïr's stance in Assassin's Creed, complete with his ring finger bent back to his palm, a reference to Altaïr's missing finger.

"Back in the time of the Crusades, members of the order of Assassins used what is called the Assassin's Straw Box to hide and get close to their enemies."

- Kazuhira Miller, commenting on the newly procured item.

In Main Ops 16, one of the missions in Metal Gear Solid: Peace Walker, a unique box made of straw dubbed the Assassin's Straw Box could be obtained. To do so, the player must ensure that there was a vacant slot in the equipment section. They then must climb onto the roof of the shack above where the straw box was, and then perform a Leap of Faith into it. The Leap was accompanied by an eagle's screech, similar to its mechanism in the Assassin's Creed series. Right after obtaining the straw box, one of the game's main supporting characters, Kazuhira Miller, mentions its use during the Third Crusade (the time period of Assassin's Creed), and how it was used by the Assassin order. After the aforementioned mission was completed, the Assassin's Straw Box was made available in the inventory.

The box could hold two people simultaneously and included a special function not found in other box items: players were able to knock out soldiers while hiding in the box and if another player was present, the unconscious soldier can be recruited via Fulton Recovery. Continued use of the box damages the item, and can be destroyed completely for the rest of the mission if overused.

Prince of Persia series

If Agent 47 looks through his scope at the very top of the building, he will see a hooded man perched on a ledge. If he shoots the man, an eagle sound can be heard as the man falls. Shooting the man earns the player the "Leap of the Ninja" achievement, referencing the Leap of Faith.

The Witcher 2
During one mission in , Geralt could walk up to some haystacks underneath a structure resembling a View Point and find the body of a white-robed man, who looked suspiciously like an Assassin, that appeared to have died when his Leap of Faith failed.
