Enzio must defend the districts captured by using a tower defense minigame, where he controls assassins from rooftops against waves and waves of Templar soldiers and siege equipment. While capturing a district is really similar to Assassin's Creed: Brotherhood, the Templars will try to capture it back.

The game also added and expanded upon the seizing districts of the city from the Templars. As well as the hookblade, Enzio has hundreds of different bomb variations that he can use, which are crafted. The hookblade speeds up navigation around the city by around 30%. Though in this game there's a new addition, an item called the hookblade, which is used to zip-line across the city or grab enemies to yank them in for a combo attack. The game follows the series' open world gameplay. Ezio must follow in the footsteps of his spiritual mentor, Altair, to lead him to discovery and revelation. The search for these seals takes him to Constantinople, where he finds out that there is an army of Templars forming in the city, threatening to destabilize the region. There he finds an ancient artifact, which is locked away, and can only be opened with five keys. Ezio thus sets out on a pilgrimage to his predecessor's homeland of Masyaf, which he discovers has been overrun by the Templars. The new Grand Master of the Assassin Order, after freeing Italy from the Templar threat, questions his life as an Assassin, wondering how it would've been had he never been one.

Along the road to doing that, he starts to relive the later memories of Ezio. He can do this by connecting his mind by locating a key memory. There he hopes to reassemble his fragmented mind, to awake from his coma. Once in the Animus, he falls into a back door known as the Black Room. He then returns to the Animus to retain his consciousness. Once Desmond Miles is forced to stab his ally, he falls into a coma. Assassin's Creed: Revelations is an entry in the historical series with an open world environment and a focus on stealthy gameplay.
