The Last of Us is an action-adventure survival horror video game. The Last of Us is played from a third-person perspective; players use firearms, improvised weapons and stealth to defend against hostile humans and zombie-like creatures infected by a mutated strain of the Cordyceps fungus. "Listen mode" lets players locate enemies through a heightened sense of hearing and spatial awareness. Players can also upgrade weapons and items using items scavenged from the environment. In the game's online multiplayer, up to eight players engage in co-operative and competitive gameplay in recreations of single-player settings.
