Dual-wielding is a form of combat, wherein one uses a pair of weapons in conjunction with one another. This is often to allow an easy shift between long and short-ranged attacks.
During the Renaissance, Ezio Auditore da Firenze and his Assassin recruits were able to dual-wield multiple combinations of weapons. Other than the throwing knives and short blade pair, Ezio could wield the Hidden Gun with any primary, medium-ranged weapon – such as swords and blunt weapons – and poison darts with the Poison Blade. His recruits wielded their Hidden Gun with almost any other weapon. During his time in Constantinople, Ezio could also dual-wield a variety of bombs with his primary weapon.
During the French and Indian War and the American Revolutionary War, both Haytham Kenway and Connor would always dual-wield their weapons in combat, with Haytham proficient in the use of a sword, a flintlock pistol and his Hidden Blades.
Meanwhile, Connor possessed a combination of swords, a tomahawk and various other weaponry. Accompanying this, he often used his Hidden Blade with almost any other weapon, utilizing its pivot attachment for it to function as a dagger. He also carried two flintlock pistols, some of which possessed the capacity to fire multiple times.
During the Louisiana Rebellion, Aveline de Grandpré dual-wielded her weapons in combat. The weapons she dual-wielded include, a whip, firearms, swords, knives, a blowpipe, a sugar-cane machete and Hidden Blades.
Only a few enemies, such as Papal Guards, Cesare Borgia, and the Janissaries, were able to dual-wield, typically using a pistol alongside a longsword in combat. Officers and Jägers would also dual-wield weapons in a similar manner.
