Fallout 2: A Post Nuclear Role Playing Game is a 1998 role-playing video game developed by Black Isle Studios and published by Interplay Productions. It is a sequel to Fallout (1997), featuring similar graphics and game mechanics. The game's story takes place in 2241, 80 years after the events of Fallout and 164 years after the atomic war which reduced the vast majority of the world to a nuclear wasteland. The player assumes the role of The Chosen One, the grandchild of the first game's protagonist, and undertakes a quest to save their small village on the West Coast of the United States.

A role-playing video game, a role-playing game (RPG) or computer role-playing game (CRPG), is a video game genre where the player controls the actions of a character immersed in some well-defined world, usually involving some form of character development by way of recording statistics. Many role-playing video games have origins in tabletop role-playing games and use much of the same terminology, settings, and game mechanics. Other major similarities with pen-and-paper games include developed story-telling and narrative elements, player character development, complexity, as well as replay value and immersion. The electronic medium removes the necessity for a gamemaster and increases combat resolution speed. RPGs have evolved from simple text-based console-window games into visually rich 3D experiences.
