Fallout Tactics: Brotherhood of Steel

Fallout Tactics: Brotherhood of Steel, better known as simply 'Fallout Tactics, is a turn-based/real-time tactical role-playing game based in the post-apocalyptic Fallout universe. Developed by Micro Forté and published by 14 Degrees East, Fallout Tactics was released on 14 March 2001 for PC. The game follows a squad in the fictional Brotherhood of Steel as it becomes engaged in a desperate war. Although the game takes place in the Fallout universe, it does not follow or continue the story of either Fallout or Fallout 2. Fallout Tactics shipped with a bonus CD when it was pre-ordered. The bonus CD included Fallout: Warfare, a table-top miniatures game based on the Fallout universe, as well as a bonus mission for the main game which occurs in Springfield.

Due to contradictions with the story and setting of those games, the original Fallout creators and, initially, the creators of Fallout 3 considered Fallout Tactics non-canon. With the release of Fallout 3 by Bethesda Softworks, however, the existence of the game's Brotherhood splinter faction is considered at least semi-canon, with Brotherhood of Steel members in-game explaining that the Chicago-based Brotherhood featured in Fallout Tactics "...went rogue. Long story."
