Fallout 4: Nuka-World is an expansion pack for the 2015 post-apocalyptic action role-playing video game Fallout 4. It was developed by Bethesda Game Studios, published by Bethesda Softworks, and released on August 30, 2016, for Microsoft Windows, PlayStation 4 and Xbox One. It is set in the eponymous fictional amusement park Nuka-World. As with Fallout 4, Nuka-World can be played in both first-person and third-person perspectives. The player controls the protagonist during their journey through Nuka-World, a former amusement park, now run by groups of raiders. Nuka-World's main gameplay consists of both questing and exploration. Upon completion of quests, the player is rewarded with both the franchise's fictional currency, bottle caps from Nuka-Cola bottles, and experience points.
