New Jackdaw Upgrades: Naval combat is modernized with four new secondary fire modes, a redesigned swivel gun, and three recruitable Naval Officers (Lucy Baldwin, The Padre, and Deadman Smith) who grant active perks.Reworked Stealth & Combat: Edward can now crouch anywhere. Rigid tailing and eavesdropping missions have been altered to prevent instant "desynchronization" failures. Melee combat is built around parries and dynamic physics, though combat is strictly limited to dual swords over the hidden blades for active striking.
