Joel must smuggle fourteen-year-old Ellie to a militia group called the Fireflies, twenty years after an outbreak of a parasitic fungus that takes over human neural functions. Along the way, they must avoid deadly authorities, infected hosts and violent survivors.
The Last of Us follows this mission through a narrative-driven single-player campaign. Players explore varied environments from a third-person perspective, using stealth and combat against infected creatures and hostile humans. A separate mode, Factions, features competitive online multiplayer.
