Naval aspects from previous games will return with the player controlling Shay’s ship, Morrígan. The Morrígan has a shallower draft compared to Edward Kenway’s Jackdaw from Assassin’s Creed IV: Black Flag, allowing for river travel. New features include new ship-based weapons such as releasing an oil slick which can then be ignited, Puckle guns, and the ability for enemies to board the Morrígan during ship-to-ship combat. The arctic environment also features into naval gameplay. The underwater diving missions featured in Black Flag do not exist in the North Atlantic, as swimming causes the player’s health to rapidly deplete due to the frigid water.
For combat, the game introduces an air rifle, 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 a grenade launcher, which fires off shrapnel grenades and other loads. Enemy Assassins feature archetypes similar to previous games, using skills that players have been using since the original game; they can hide in bushes, blend in with crowds, and perform air attacks against the player.
