In Assassin's Creed: Revelations, the new weapon that lets Ezio move along ropes and snag distant objects is the Hookblade. It combines a conventional Assassin wrist blade with a hooked extension that broadens Ezio's movement options.
Ezio uses the Hookblade to catch ledges, swing from zip lines, cross gaps, and climb more quickly through Constantinople. Its hook can also help him pull enemies or objects within reach during selected gameplay situations. The weapon is introduced as an adaptation suited to the city's architecture and extensive network of lines.
The game takes place mainly in Constantinople, the capital of the Byzantine Empire, during the early sixteenth century. Ezio is searching for Altaïr's seals, which allow him to access memories of the earlier Assassin.
The Hookblade is different from the Hidden Blade, which remains Ezio's signature assassination weapon. It is also not the Rope Dart associated with later and earlier series mechanics; the Hookblade's defining feature is its combination of traversal and close-range utility.
