Assassin's Creed: Revelations

Plot
After having freed Italy from the Templar threat, the Mentor of the Assassin Order, Ezio Auditore discovers that there is a new army of Templars forming in the city of Constantinople - threatening to destabilize the region. Ezio must follow in the footsteps of his spiritual mentor and forefather Altaïr Ibn-La'Ahad, which will lead him to discovery and revelation. Ezio will be searching for seals containing Altaïr's memories, through which the player can control Altaïr.

The city of Constantinople will be divided into four districts: Constantin, Beyazid, Imperial and Galata. Though players will also be able to visit Cappadocia. 

Gameplay
The gameplay system from Assassin's Creed: Brotherhood will be the basis for Revelations, though Ezio's skills, like free-running and combat, will be upgraded with new features.

A new item called the Hookblade will be introduced which will allow Ezio to use ziplines throughout the city, speeding up navigation by around 30%. The hookblade would also be able to be used to pull enemies towards you, enabling the player to start or prolong combination attacks. 

Eagle Vision will now be known as Eagle Sense, which would allow the player to focus on a character and determine the route taken by them, as well as giving the player an estimation of where they will go, which could be useful for ambushes or locating a secluded place to strike a target. This new ability will also allow Ezio to listen in on far away conversations or even hear someone's heartbeat. 

A new crafting system will allow creation of bombs, with the option of upto 300 different types. These bombs could be utilised along with Eagle Sense to lay traps for guards. 

The concept of Borgia Towers has been expanded, and in order to neutralize Templar presence, various assault scenarios must be completed. The liberated buildings will be known as "Assassin's Dens" and control over these dens can be lost when Templars try to overtake them once more. These assaults will be triggered when the player's notoriety increases, and the Assassin's Den would be lost if they fail to neutralize the attack.

Though, Assassin's Dens can be protected, provided that the player assigns a Master Assassin to overlook the building and prevent any further Templar attacks on the building they are posted at. The cap for the Apprentice Leveling system would also be raised to 15.

Meanwhile, the modern day aspect of the game will also be upgraded with a new feature, tentatively labeled "revolutionary gameplay", in which Desmond Miles will need to change the construct of his ancestors' memories and in the process, unravel the future. He will re-enter the Animus and find a safe-mode called "The Black Room" where he will reintegrate the splintered layers of his subconscious. 

Multiplayer
The game will come with a multiplayer mode like its predecessor Assassin's Creed: Brotherhood, though it will be upgraded with new modes, maps and characters to refine the experience. It will now feature customization, allowing the player to choose their own weapon and change their appearance, editing clothes and other minor features.
