A remastered version of Revelations, along with Assassin's Creed II and Brotherhood, was released as part of The Ezio Collection compilation for the PlayStation 4 and Xbox One on November 15, 2016, and for the Nintendo Switch on February 17, 2022.

The framing story is set in the 21st century and features the series protagonist Desmond Miles who, after falling into a coma during the events of Brotherhood, must relive the memories of his ancestors through the Animus device in order to awaken and find a way to avert the 2012 apocalypse.

In Constantinople, Ezio becomes caught in a war of succession for the Ottoman throne and must unravel a conspiracy by the Byzantine Templars, who are attempting to reclaim control of the city and acquire the keys to Altaïr's library themselves.

Revelations features an open world and is played from the third-person perspective, with a primary focus on using Ezio's and Altaïr's combat, climbing and stealth abilities to eliminate targets and explore the environment.

Most notably, several editions included an animated short film, titled Assassin's Creed: Embers, which serves as a proper conclusion to Ezio's story, and which was later re-released as a free download on the PlayStation Store.

Downloadable content (DLC) released for the game includes new maps and characters for the multiplayer mode, and a story expansion titled The Lost Archive, which adds more platforming levels to the modern-day.

While the base gameplay remains virtually unchanged from the previous title, Assassin's Creed: Brotherhood, Revelations does add several new features; most notably, the "Hookblade," which acts as a replacement for Ezio's traditional dual Hidden Blade (which is broken at the beginning of the game).

Introduced early on in the story, this mechanic allows Ezio to experiment with different shells and ingredients to create bombs with various effects, such as smoke to distract guards or lethal explosions that can take out large groups of enemies.

When this occurs, the player will have to defend the tower in a "Den Defense" minigame, where they control a group of Assassins from the rooftops and must fight off multiple waves of Templar soldiers and siege equipment.

Another returning feature from Brotherhood is the ability to recruit Assassin initiates and call them for support during missions or send them on assignments to other cities around the Mediterranean Sea, which are controlled by the Templars.

Other side activities include Piri Reis Missions, which teach the player about the different types of bombs that can be crafted; Guild Challenges for any of the three ally factions in the game (Thieves, Mercenaries, and the Romani); and finding rare books for Ezio's love interest, Sofia Sartor.

These sequences play differently from anything that has come before in the series, as they involve first-person platforming and puzzles, while the story is provided in the form of narration by Desmond, who recounts his life prior to the events of the first Assassin's Creed game.

Assassin's Creed Revelations features all three of the series' major characters up until this point: Desmond Miles (Nolan North), Altaïr Ibn-La'Ahad (Cas Anvar), and Ezio Auditore da Firenze (Roger Craig Smith).

[23] Other in-game characters include Yusuf Tazim (Chris Parson),[24] Piri Reis (Alex Ivanovici),[25] Tarik Barleti (JB Blanc),[26] Ishak Pasha,[27] Sultan Bayezid II,[28] Al Mualim (Peter Renaday),[29] and Niccolò and Maffeo Polo.

[30] Following the events of the previous game, Shaun Hastings stays in Rome to attend Lucy Stillman's funeral, while Rebecca Crane takes the comatose Desmond to his father, William Miles, in New York.

Hoping that Desmond will find the answers he could not and will make everyone's suffering be worth it in the end, Ezio activates Altaïr's Apple before retiring from the Assassins in order to start a normal life with Sofia.

The Apple displays a message from Jupiter, a member of the First Civilization, who explains that his race had studied methods to save the Earth from destruction, and transmitted all the collected data to a central vault: the Grand Temple.

After reaching level 50, the player is dubbed an active agent, and assigned the task of finding and capturing the current Mentor of the Assassin Order: William Miles.

In 2010, he was tasked with infiltrating Abstergo Industries' Animus Project laboratory in Rome in order to uncover what Warren Vidic hoped to achieve by exploring the genetic memories of various Assassins.

Becoming Subject 16 of the Animus Project, Clay was forced to relive his ancestors' memories to the point of being driven insane, but eventually learned that Vidic was searching for the locations of various Pieces of Eden.

When Lucy eventually found out that Clay had learned about this plan, she got rid of the evidence proving he knew the truth and imprisoned him inside the facility, both to protect him and to keep her true allegiances secret.

[35] In February 2011, Ubisoft CEO Yves Guillemot confirmed that the next Assassin's Creed game would be released during its next fiscal year, which starts on April 1, 2011, and ends on March 31, 2012.

McDevitt claimed original Creed protagonist Altaïr had his story arc written for two years, and that Ezio's ultimate fate was planned during the development of Brotherhood.

The beta offered access to nine characters (The Sentinel, The Vanguard, The Guardian, The Vizier, The Thespian, The Deacon, The Bombardier, The Trickster, The Champion – all boasting different abilities), three maps (Knight's Hospital, Antioch, Galata) and four playable modes (the previously seen Wanted and Manhunt options joined by new Deathmatch and Artifact Assault variants).

[51] Additionally, Ubisoft released an Assassin's Creed: Revelations Avatar collection Xbox 360, which includes a Codex prop, Desmond's black hoodie, and a pet eagle.

"[68] 1UP gave the game a rating of B+, stating "While Revelations lacks that one supreme improvement or standout mechanic that defined AC2 and Brotherhood each, it's still a damn fine sendoff for Altair and Ezio.

"[63] Edge gave the game a rating of 7 out of 10, saying that "unlike the elegant lead, who's grey-haired but unbowed by the end of the adventure, Assassin's Creed has been quietly compromised by age.

It's a game of nearly and might-have-been: summed up by the hook blade, a supposedly key new feature which in practice merely extends Ezio's reach slightly, and allows him to glide down the occasional zipline.

"[73] GameTrailers also gave the game a rating of 8.8 out of 10, saying that "the engine is a bit long in the tooth and some of the content isn't entirely worth exploring, but if you're looking for an unforgettable top-shelf action/adventure, heed the creed.

"[75] UK Official PlayStation Magazine gave the game a rating of 9 out of 10, stating "As a conclusion for Ezio's chapter, Revelations proves an utterly brilliant swansong.
