Fallout 76

Twenty-five years after the Great War, residents of Vault 76 emerge on Reclamation Day to re-colonize the Appalachian wasteland. The player character discovers that a mysterious plague called the Scorched Plague, spread by massive mutated creatures known as Scorchbeasts, has wiped out most of the region's inhabitants. Guided by the Vault Overseer's secret mandate to secure nuclear missile silos, the player investigates the fates of several factions that tried to stop the plague, including the Responders, the Free States, and the Brotherhood of Steel. After gaining the support of MODUS, an Enclave AI beneath the Whitespring Resort, the player locates the Scorchbeast nest, launches a nuclear strike, and defeats the Scorchbeast Queen, shattering the creatures' hive mind and neutralizing the threat to the wider wasteland.

Fallout 76 is an online action role-playing game and the first multiplayer entry in the Fallout series. Set in 2102 in Appalachia, West Virginia, players control a resident of Vault 76 who ventures into the open world 25 years after a nuclear war. The game features exploration, questing, base building, and combat against mutated creatures and hostile factions. It can be played solo or cooperatively, with players sharing servers and engaging in trade or PvP combat.
