For combat, the game introduces an air rifle, similar to the blowpipe from Black Flag, which allows the player to silently take out enemies at a distance. The air rifle can be outfitted with a variety of different projectiles, such as firecrackers. The player can also use it as a grenade launcher, which fires off shrapnel grenades and other loads. Hand-to-hand combat has been slightly altered, and now enemy attacks can be countered with timing, similar to the Batman: Arkham series of games. Enemy Assassins feature archetypes similar to previous games, using skills that players have been using throughout the series; they can hide in bushes, blend in with crowds, and perform air assassinations against the player. Poison gas can now be used as an environmental weapon, and Shay has a mask that can mitigate its effects, and Shay's Eagle Vision also takes elements from the multiplayer feature of the previous games that allowed them to track an enemy's position via a radar-like system, and even without it, Shay is able to detect enemy presence with the screen edges going red and is also able to accurately foresee when and from where his enemies will strike.
