隠しネタ（Easter eggs） はゲーム内に意図的に隠され仕込まれたジョークや引用の数々である。アサシンクリードシリーズにはそれが有り、他のゲームでもアサシンクリードに関する隠しネタが含まれている
- 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.
Assassin's Creed 編集
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.
Assassin's Creed II 編集
ミッション「知識は力なり」と「」ではダミーターゲットの死体を探ると鍵が見つかるが、何の意味もない。 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.
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 when entering other buildings such as the Villa Auditore lightened or darkened 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.
Assassin's Creed: Brotherhood 編集
Red footprints 編集
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 編集
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 編集
The achievement "Grand Theft Dressage" was a clear reference to the Grand Theft Auto game series.
Machiavelli's works 編集
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 famous (and brief) book, "The Prince."
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 DLC.
Mario references 編集
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 編集
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 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.
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 編集
Assassin's Creed: Revelations 編集
Lingering enemy 編集
Hello World 編集
Monty Python 編集
In the mission 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 fight and, after both his arms and legs were cut off, said "Alright. We'll call it a draw."
Muhammad Ali 編集
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. This was a reference to the famous boxer, Muhammad Ali, who described his fighting style as "Float like a butterfly, sting like a bee."
Assassin's Creed (French comic) 編集
Prince of Persia 編集
In the first tome of the novel, during Desmond's flashback, the Prince of Persia, 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 編集
The characters, gameplay elements, and plot of Assassin's Creed were also featured in various other media.
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 Hidden Blades on the left arm.
In AdventureQuest Worlds, there was 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 Hashashin Armor included two Hidden Blades, though they were located on top of the player's wrist, rather than on the bottom.
Dead Island 編集
In Dead Island, there was a wieldable knife named "Assassin's Greed". Accompanying this, there was also a modification for brass knuckles called the "Assassin's Poison Mod".
Dragon Age II 編集
Dungeon Defenders 編集
Gaia Online 編集
During the 2011 Halloween event in Gaia Online, Edmund, the shop owner for H & R Wesley, was dressed as Ezio.
Grand Theft Auto IV 編集
In Grand Theft Auto IV, after completing a set of assassination missions for a mysterious figure called 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.
inFAMOUS 2 編集
Located in the fictional city of New Marais, several cinemas and theaters in inFAMOUS 2 featured movie titles that were direct puns of 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.
Invictus Games 編集
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.
Metal Gear Solid 4 編集
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 game's title) or input a password in the Extras section. Specifically, the password was been 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 would bend his ring finger back into his palm, which was maintained as long as he wore the costume, a reference to Altaïr's missing ring finger.
Metal Gear Solid: Peace Walker 編集
- "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.[src]
In one of the missions in Metal Gear Solid: Peace Walker, namely Main Ops 16, 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, 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 main protagonists, Kazuhira Miller, mentioned its use during the Third Crusade (the time period of Assassin's Creed), and how it was used by the Assassins. After the aforementioned mission was completed, the Assassin's Straw Box was available in the inventory.
The box could hold two people simultaneously and included a special function not found in other box items: knocking out guards while hiding in the box and recruiting the knocked-out soldier using Fulton Recovery (if another player was present). Continued use could damage the item, to the point where the box would be destroyed completely.
Prince of Persia 編集
In Prince of Persia (2008), Altaïr's costume was available as a free DLC for use by the Prince. Additionally, an achievement entitled "Assassin's View" could be unlocked by standing on a View Point upon the Martyr's Tower.
Altaïr's Costume could also be purchased in Prince of Persia: Prodigy, via Uplay.
In RuneScape, the quests Stolen Hearts and Diamond in the Rough contained many similarities to Assassin's Creed, such as stalking targets, free-running across rooftops and an "Eagle jump" into a cart of hay.
Saints Row: The Third 編集
In the sandbox game Saints Row: The Third, an achievement entitled "Everything is Permitted" was awarded when one eliminated all assassination targets.
Soul Calibur V 編集
In Soul Calibur V, the character Dampierre used a hidden blade called "Hidden Edge" as his ultimate weapon.
The Elder Scrolls V: Skyrim 編集
In the fifth Elder Scrolls game, Skyrim, the Dovahkiin may travel to a place called the "Bards Leap Summit"; a large cliff sporting a plank at the top, with a large drop to a pool below, resembling a View Point for a Leap of Faith. If the Dovahkiin survived the drop, a ghost would be summoned who would speak about his failed attempt.
The Saboteur 編集
In The Saboteur, the main protagonist Sean Devlin earned a racing car with white stripes, named Altaïr, which was nicknamed "The Flying Eagle."
The Simpsons 編集
In the fifth episode of season 23 of The Simpsons, "The Food Wife," a poster could be seen in the back of the fictional games convention E4, featuring a hippie with two Hidden Blades and the title "Assassin's Creed - Summer of Love," besides some other game parodies.
The Witcher 2 編集
During one mission in The Witcher 2, 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. The white-robed man also had a blade covering his arm that looked like an Assassin's Hidden Blade.
If the player examined the body, Geralt said, "Hmm... Guess they'll never learn." From there, he would be granted a hidden ability called "Assassin."
