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.
Psychiatrist Carl Jung was referenced throughout the Assassin's Creed series:
- The Animus was named after Jung's anima and animus.
- Women in the series such as Eve, Maria Thorpe, Maria Auditore da Firenze and Sofia Sartor (mostly Assassins as well as wives to notable male Assassins) share 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 collective unconsciousness.
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.
An arrangement of windows on certain buildings in Damascus and Acre were shaped like the torso of G1 Optimus Prime, a character from the Transformers franchise, when in his alternate form of a truck.
Occasionally 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, 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 The Dark Knight.
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.
A giant squid could be found within the Assassin Tomb beneath Santa Maria della Visitazione. If Ezio looks into the water near the first lever for about one minute, a cutscene played showing a large squid swimming by. If Ezio looks down again, a second cutscene shows a tentacle coming out of the water, in front of Ezio.
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.
Grand Theft Auto
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 "Virtù", 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, The Prince.
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.
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.
Another Mario reference was the achievement One-Man Wrecking Crew, which name is a reference to the game Wrecking Crew, that features Super Mario as the protagonist. It also showed the picture of a Super Mario hammer.
Just before reuniting with Leonardo da Vinci, Ezio came across an anachronistic factory-made cardboard box, though he looked away when Leonardo came around the corner. This may have been a reference to the Metal Gear 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.
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.
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.
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.
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.
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 Monty Python And The Holy Grail, 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."
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, Muhammad Ali, who described his fighting style as "Float like a butterfly, sting like a bee."
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 Marvel Comics' superhero Spider-Man and his ability to scale up and around buildings with incredible speed.
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 Alice In Wonderland.
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.
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 Konami Code, 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.
Cool Hand Luke
Often, civilians would utter "What we have here is a failure to communicate", which is the famous line from the film Cool Hand Luke. 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.
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.
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 Spyro the Dragon series.
The Last of the Mohicans
There is a QR code hidden in an image above the MMA ring while Desmond is in Brazil.
This is the first time the Headless Horseman is referenced to in the entire Assassin's Creed series. When Connor investigates the beheaded bodies under the order of the Frontiersmen, he sees the Headless Horseman with a pumpkin for a head.
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 Predator movie franchise, in which the Predator stalks its prey from tree branches with thermal vision, before killing them with a plasma cannon.
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.
Mr. Livingstone, I presume?
The title of the memory "Mister Walpole, I Presume?" is a reference to the explorer Henry Morton Stanley, famed for reportedly asking, "Mister Livingstone, I presume?", upon meeting fellow explorer and Christian missionary David Livingstone.
Death of a Salesman
Full Metal Jacket
Giant Squid vs. White Whale
Real-world media and weapons
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 Garneau's office containing several weapons, including a silver handled Syrian Sabre, Maria Auditore's dagger, and four replicas of the double-barreled shotgun from Red Steel 2, another Ubisoft title.
In the multiplayer, the Duellist has a weapon called the Scarlet Needle, with the description "Choose your fate: Surrender, or Die". Both are references to a character in the Saint Seiya franchise, Scorpio Milo, one being his technique and the other his famous catchphrase.
Second White Whale appearance
At the Devil's Eye Caverns wreck, if Edward collects all the chests throughout the wreck and returns to the diving bell via the rapid current caverns, a white whale will appear in close proximity to the wreck, and pass by until it swims off into the distance.
The Secret of Monkey Island
In "The Pirate Captain" memory, Edward assassinates a pirate captain called Mancomb Seepgood, which references the video game The Secret of Monkey Island, 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, Guybrush Threepwood. Additionally, during Sequence 10, Bartholomew Roberts remarks that "there's nothing like the hot winds of Hell blowing in your face," the same line uttered by the Ghost Pirate LeChuck in The Secret of Monkey Island.
The Young Ones
In Kingston, two guards can be heard conversing about the previous night. The following exchange is a rather obscure reference to the British comedy The Young Ones.
An assassin contract Edward can undertake is named "Tomb Raiders", a reference to the video game series Tomb Raider.
Abstergo employees can be heard talking about contacting a security company in Chicago, with some saying that they would work for Blume when their visas expired.
Splinter Cell: Conviction
In the area under construction, by the lift used to infiltrate Olivier's office, there are labels on a can and a dumpster which read "SMD: Ducosto, Leeuwarden, Holland." These labels were first seen on power generators in Price Airfield in Splinter Cell: Conviction.
In the Parisian Saint-Marcel district, east of La Bièvre on the open water, is a boat. Inside the boat sits a delirious man beside a pile of bodies covered with bloody rags, and exactly 23 purring cats.
Cannibal of the Tuileries
Underneath the Tuileries Garden, through an entrance along the coastline, a cannibal can be found in the same underground tunnel as a collectible cockade. Outside the tunnel lie numerous bodies covered in bloody rags, and a blood-stained stretcher. Inside, a man is chopping up a piece of meat with a cleaver, near a pot with a human bone protruding from the top. Corpses are stacked in a pile near the man, and various civilians are trapped behind sealed gates on either end of the room. Using Eagle Vision, a bloody trail can be seen leading from the trapped civilians through the pile of corpses and to the table where the cannibal is preparing his next meal.
Fear and Loathing in Las Vegas
When starting Assassins Creed: Unity, the player is introduced to a Helix menu of Abstergo Entertainment products, nearly all of which are unplayable. One of them, based on the events of Assassin's Creed II, is called "Fear and Loathing in Florence". This is a reference to the novel by Hunter S. Thompson titled Fear and Loathing in Las Vegas.
Hervé passing wind
In the Assassin headquarters beneath Sainte-Chapelle, Arno can find Hervé Quemar sitting near a fireplace reading a book. If Arno stands near Quemar for long enough, Quemar will eventually pass wind and continue to nonchalantly read his book. This can happen multiple times.
The Social Club mission "Colette" contains many references to the novel Les Misérables. Shaun also mentions the musical version, mainly his disgust that many consider the musical taking place during the French Revolution, when in actuality, the novel and play feature the failed June Rebellion of 1832.
Let them eat cake
West of the Paris Observatory in the Luxembourg district of Le Quartier Latin is an underground tunnel with an edible cake. Descending the stairs to the catacombs and turning left puts Arno Dorian in an empty room. Atop a desk in the corner of the room are two goblets, a candle, and an out-of-place, lavishly decorated three-layered cake with an egg on top. Interacting with the cake will cause Arno to eat the cake and vocally express his delight. The cake will also restore Arno's health. However, consuming the cake will cause it to disappear permanently from the player's game.
There are five cakes like this in Paris in the game, including the one in the underground tunnel. Eating them all will unlock a special fighter in the Luxembourg Palace. It is actually the Marquis de Bullion from the previous E3 gameplay trailers, and he will suddenly come to life from being a statue standing atop an over-sized cake and start fighting Arno. After killing him, fireworks will dominate the sky for a short time. If the Marquis' body is looted, 50,050 livres can be earned.
Monty Python and the Holy Grail
When helpful Parisians join Arno in fighting soldiers, they can be heard to say "Ah, now we see the violence inherent in the system," a line from the Monty Python film.
The knight that time forgot
In the eastern corner of the Hotel de Ville district, near the Temple district, the body of a knight wearing medieval armor can be found. In a small clearing between two buildings, the body of the knight rests near several chickens and a man with a basket of eggs.
Child of Light
At Abstergo Entertainment's lobby entrance, two scientists can be heard discussing Child of Light, with one trying to convince the other to play it, describing it as a "beautiful turn-based RPG". The other dismisses it on the basis of the "story being told in rhyme" and not having any "PvP Deathmatches".
Abstergo scientists can also be heard talking about oculi crafting, a game feature that gives the player various rewards and abilities.
Throughout Abstergo Entertainment's Montreal building, several real-world games, books and other Assassin's Creed media can be found. This includes Far Cry 3, Ghost Recon: Future Soldier, Splinter Cell: Blacklist, and Splinter Cell: Conviction representations such as magazines, books, etc. on the floor, atop desks, and in bookcases. On the Far Cry 3 magazine, the 3 in the title is replaced by a 5.
A poster for the rumored Assassin's Creed: Rising Phoenix game can be found in Abstergo Entertainment's Montreal building. The poster has a "Coming Soon" sticker attached to the flames below the fictional game's logo.
The missions "The Way the Wind Blows," "One Little Victory," "Freewill," "The Color of Right," "Circumstances," "Armour and Sword," "Scars," "Bravado," and "Cold Fire" each share their title with a song by Canadian rock band Rush. The mission "Caress of Steel" is also the title of a Rush album.
Assassin guards can occasionally be heard saying "Do you want to run this gang?" "Yes." "Well.....you can't." This is nearly identical to a line in the 2005 film, Serenity.
The Headless Horseman of Sleepy Hollow
At Sleepy Hollow in the Albany region of the River Valley, a character resembling the Headless Horseman, from the short story The Legend of Sleepy Hollow by Washington Irving, can attack the player. He can be found at the Old Dutch Church at night. He shares the same animations as a Brute soldier, wields a large axe, pistol and can throw grenades. As soon as he sees Shay, he will begin to attack. He is invulnerable to direct attacks and cannot be killed conventionally.
There are four known ways to defeat the Headless Horseman. The first is to shoot a pumpkin sitting atop a gravestone in the cemetery next to the church. The second way is to use a sleep grenade to cause him to drop his axe, have Shay pick up the axe, and perform the special attack with the weapon once he awakens. This will drive the axe through his nonexistent head and incapacitate him. However, he will still be alive and aware of the player. The third way to defeat him is to hang him using a rope dart. The fourth way is a haystack assassination.
A figurine of the Prince from Prince of Persia: Warrior Within can be found in a cubicle of Abstergo Entertainment's Montreal building.
"The Twin Assassins" trailer
Alhambra Music Hall posters
At the Alhambra Music Hall, posters can be found advertising Ballad of the Buccaneers and Ezio, which are homage to Edward Kenway and Ezio Auditore, respectively.
The name of Mary Anne Disraeli's dog, Desmond, is a reference to Desmond Miles, the modern day protagonist of the original Assassin's Creed and its sequels. In both cases, they were kidnapped by members of the Templar Order and rescued by Assassins later on.
Driving Miss Daisy
H. P. Lovecraft
Everything about the set of brass knuckles called Great Old One's Caress is a nod to the Cthulhu mythos created by horror author H. P. Lovecraft. The "Great Old One" refers to any member of Lovecraft's pantheon of the "Great Old Ones", space-faring deities who once ruled Earth before falling into a near-death slumber. The knuckles are also shaped like a tentacle, a physical feature common among many of Lovecraft's characters. Lastly, the knuckles's description reads that they "were hupadgh n'gha ng n'ghft", which loosely translates from R'lyehian, the language of the Great Old Ones, to "were born of death and darkness".
Queen Victoria's contact, Alfred Fleming, introduces himself as part of "Her Majesty's secret service," alluding to Ian Fleming, author of the James Bond series, particularly the novel On Her Majesty's Secret Service.
The Bohemian Girl
The Great Escape
The IT Crowd
The author of Alice's Adventures in Wonderland and Through the Looking-Glass can be found in The Strand reading the poem Jabberwocky to a group of children. The children will also ask what a bandersnatch is, which Carroll has yet to decide on. Afterwards, Carroll prepares to read another of his poems, titled The Walrus and the Carpenter.
Jabberwocky is quoted in the description for the Vorpal Kukri, which is inspired by the vorpal blade mentioned in the poem.
In the game, civilians can be seen arguing with each other in a battle of Insult Sword Fighting.
Our Mutual Friend
The memories "Our Mutual Friend" and "An Artful Plan" from The Darwin and Dickens Conspiracy reference the plot of Our Mutual Friend, the last novel completed by Charles Dickens. The characters John Hammon and Bella Wilton reference the names of John Harmon and Bella Wilfer, respectively. Hammon also uses the alias "John Rokesmith" when announcing his "death" to Bella. At the end of "An Artful Plan", Charles Darwin acknowledges that the situation feels very familiar and wonders why.
Various sea shanties featured in Assassin's Creed IV: Black Flag make an appearance in Victorian London. An accordion player in the park adjacent to the Kenway Mansion plays the song "Here's a Health to the Company", while the piano puzzle in the memory "Playing It by Ear" uses the tune of "Lowlands Away".
A flute player can also be found playing "Padstow's Farewell" and "Admiral Benbow". Lastly, a man near the River Thames sings the shanties "Leave Her Johnny", "All for Me Grog", and "Barbara Allen".
Shall We Dance?
The achievement name for completing Sequence 9 is titled Shall We Dance?, referencing a musical number from Rodgers and Hammerstein's The King and I.
The Huntsman's Outfit for Jacob is homage to the iconic look of Sherlock Holmes, as illustrated by Sidney Paget.
Somewhere That's Green
Sweeney Todd: The Demon Barber of Fleet Street
"The Fiend of Fleet Street" is a Dreadful Crime that features a replica of the Sweeney Todd scenario. The characters Feeney Sodd, Mrs. Moffat, and Tobias Jeffers reference the names of Sweeney Todd, Mrs. Lovett, and Tobias Ragg, respectively.
At one point, one of the Rooks mentions, "I opened a new pie shop on Fleet Street. Brave move considering what happened to the last one."
Ezio's Family Theme
A guardian can be heard whistling the Ezio's Family theme from the Assassin's Creed II soundtrack.
Prince of Persia
In the first tome of the comic, during Desmond's flashback, the Prince, the main protagonist of the 2008 reboot of the famous Ubisoft series, Prince of Persia, appeared on the screen of the arcade game monitor at the L'Horizon bar.
1992 Summer Olympics
At the beginning of the chariot races in the Lageion Hippodrome you can sometimes see an archer mirroring Antonio Rebollo's lighting of the Olympic flame during the opening ceremony of the 1992 Summer Olympics in Barcelona. 
Conan the Barbarian
There is a parody of a famous line in the movie Conan the Barbarian ("what is best in life?") during the dialogue between Bayek and Khemu while searching for the right star constellation at the Apis stone circle in the Isolated Desert (see Bayek's Promise).
During the mission Curse of Wadjet, Bayek uses a clear reference to Indiana Jones, saying "Snakes again, why did it have to be snakes?", referring to the famous quote from the 1981 movie Raiders of the Lost Ark.
During the mission The Greater Good in The Hidden Ones DLC, Gamilat will repeatedly try to knock Bayek off the platform into the water so as to target him with a ballista. If he succeeds, he will say "It's over Bayek, I have the high ground!" This is a reference to the climactic duel between Obi-Wan Kenobi and Darth Vader on Mustafar in the film Star Wars: Episode III Revenge of the Sith (2005) where Obi-Wan quotes this famous line to Vader as he leaps to a lava bank on a higher elevation before dealing the strike that cripples him for life.
Pirates of the Caribbean
On Layla's computer there is a file detailing the death of Olivier Garneau and showing security footage of his murder at the hands of Aiden Pierce.
Asterix and Cleopatra
In The Hidden Ones (DLC), at the nome of Madiana, slightly north-west of the leopards lair, you can access to a cave by climbing up the left side of a stone arch. In this cave, there is a small camp with a fire and a stone plate. If the player goes in photo mode and looks at the stone, he will be able to identify the drawing of a pudding with multiple other drawings under it. This is a reference to the cult (for francophones) scene in Asterix and Cleopatra, the Franco-Belgian animated film of 1968, in which two scribes, Pyradonis and Krukhut, prepare an arsenic pudding, with ridiculously toxic substances involved in its preparation. The three last lines are the only that directly come from the scroll containing the recipe in animated film, the others being original to this game.
Final Fantasy XV
In Layla Hassan's hideout, three items related to the Final Fantasy series, especially Final Fantasy XV, can be found: a Moogle doll, a Cactuar statuette, and a Chocobo sticker
Among the various mercenaries met over a playthrough is one with the epithet The Knee Destroyer. According to the description, the mercenary used to be friends with one of the finest mercenaries on Delos until said friend was shot in the knee. This recalls one of the most famous NPC-guard lines from The Elder Scrolls V: Skyrim: "I used to be an adventurer like you, then I took an arrow in the knee."
Ubisoft's logo in Elysium
While traversing the simulation of Elysium created by Aletheia, the place is filled with asphodel flowers, especially the aptly named Asphodel Fields. If you observe the fields from a height, Ubisoft's logo is clearly visible.
Assassin's Creed in other media
Characters, gameplay and story elements as well as concepts from the Assassin's Creed series are featured in various other media, either as parodies or references.
Academy of Champions: Soccer
Altaïr Ibn-La'Ahad and other Ubisoft characters appear in Academy of Champions: Soccer as playable characters.
In AdventureQuest, the Assassin job class had a level 10 Guardian skill called "Finishing Blow." After clicking this, it had another button called "Assassin's Creed." Additionally, the armor "Whispering Raiment" had two small blades on the left arm, referencing the Assassins' Hidden Blade.
In AdventureQuest Worlds, there were two outfits available for purchase at the suggestion shop in Yulgar's inn, which were the "Hashashin Armor," priced at 500,000 gold for free players, and the "Armored Hashashin Armor," priced at 300,000 gold for upgraded members of the game. The armor included two "hidden blades," though they were located on top of the player's wrist, rather than on the underneath.
In Dead Island, there was a wieldable knife named "Assassin's Greed" (referencing the series' title). Accompanying this, there was also a modification for brass knuckles called the "Assassin's Poison Mod".
Dragon Age II
There is an achievement in Fable Anniversary called "Ass Creed". It requires the player to wear an assassin outfit and then do a the fart expression. The achievement description will then read, "You were deadly alright; look at the size of that hole in your trousers! Quick, find a haystack!".
In Fantastic Four, the first gameplay walkthrough of Assassin's Creed: Syndicate can be seen playing on one of Victor von Doom's computer screens.
Far Cry 3
In Far Cry 3, one of the collectible Letters of the Lost Lab mentioned "I question using these so-called scientists. They speak of Pieces of Eden and Edison's electrical experiments into genetic memory." 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 quoted the phrase in Assassin's Creed III. However, they continue quoting dialogues from the book throughout the game.
Far Cry Primal
If the player heads far south on the mini-map and stands at the base of a hill, they will come across a massive Assassin's insignia scrawled in the dirt.
There is a trophy the player can unlock called "Kanda Of Faith", where the player's character climbs the mountain Kanda and jump off into water below to unlock it.
Final Fantasy XIII-2
Ezio's outfit from Assassin's Creed: Revelations appears in Final Fantasy XIII-2 as a downloadable costume.
During the 2011 Halloween event in Gaia Online, Edmund, the shop owner for H & R Wesley, was dressed as Ezio Auditore from Assassin's Creed II.
Grand Theft Auto IV
In Grand Theft Auto IV, after completing a set of assassination missions for a mysterious figure named the Fixer, the player received an achievement called "Assassin's Greed", which was a direct play on the Assassin's Creed name. Moreover, the requirement for the achievement was the completion of nine assassination missions, which paralleled the first Assassin's Creed game, in which Altaïr was tasked by Al Mualim to kill nine Templars in exchange for his reinstatement as a Master Assassin.
In the Sniper Challenge from Hitman: Absolution, Agent 47 will see a very tall building in the background with two antennas. 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.
Hotline Miami 2: Wrong Number
In Hotline Miami 2, there is a trophy titled, "Assassin's Cred", which is an obvious poke at Assassin's Creed because its name and how you get the achievement. It's earned in the level, "No Mercy", and is obtained by stealth-killing every enemy on floor 1 using nothing but your silenced pistol.
One weapon from the video game Hyperdimension Neptunia Victory, named the "Freak Diamond", has the description of "A replica of an assassins blade from days of yore. No matter the height, you'll be fine if you fall into a haystack."
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: 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.
The IT Crowd
The episode "The Dinner Party" sees main character Roy ask the model he escorted home if he can borrow her copy of Assassin's Creed, holding up the game case. The recording and broadcast of the episode in 2007 actually predated Assassin Creed's release by months.

In the Ironhide Studios game, the two top level "Barracks" towers are the Assassins and the Templars, a direct play on the rivalry between the Assassins and the Templars in the Assassin's Creed series.
LEGO The Lord of the Rings: The Video Game
In LEGO The Lord of the Rings, a Leap of Faith could be performed from a wooden board that resembled a Viewpoint at the highest point in Weathertop. On performing it, the character would land into a small pond, complete with an eagle-like sound as the Leap was done.
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 LittleBigPlanet 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. These outfits are also available in LittleBigPlanet 2.
Metal Gear 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 the password "aottrykmyn" in the "Extras" section.
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, was exactly like Altaïr's stance in Assassin's Creed, complete with his ring finger bent back to his palm.
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 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 could be recruited.
