Ghost of Tsushima is an action-adventure stealth game features a large open world, without waypoints, which can be explored without guidance. Players can engage in direct confrontation with enemies using weapons such as a tachi, which can also be used to chain up a series of fatal strikes after highlighting specific enemies. Alternatively, using stealth allows to evade enemies and strike them silently with tools such as firecrackers to create distractions, smoke bombs to disorient alerted foes, and kunai for striking multiple enemies.
