Fallout: Brotherhood of Steel is an action role-playing game and the fourth video game to be set in the Fallout universe. It was also the first to be made for consoles, and the last to be made during Interplay's initial run on the series, before the rights passed to Bethesda Softworks. The game chronicles the adventures of an initiate in the fictional Brotherhood of Steel, a militant quasi-religious organization that has come to power in a post-apocalyptic world.
