Assassin's Creed Revelations is a third-person action-adventure stealth game set primarily in Constantinople during the rise of the Ottoman Empire. Players control an aging Ezio Auditore as he searches for five keys to unlock a library built by Altair, while also playing brief flashback sequences as Altair and first-person platforming sections as Desmond Miles. Gameplay retains the series' mix of combat, climbing, and stealth, adding a hookblade for faster traversal and zipline access, a bomb crafting system, and a tower defense minigame. The multiplayer mode from Brotherhood returns with expanded maps, characters, and modes.
