The first two titles in the series (Fallout and Fallout 2) were developed by Black Isle Studios, and had stronger roleplaying characteristics than the subsequent two spin-offs. Micro Forté and 14 Degrees East's Fallout Tactics: Brotherhood of Steel of 2001 was a tactical role-playing game. In 2004, Interplay, having closed Black Isle Studios, brought out an action game with RPG elements for PlayStation 2 and Xbox, Fallout: Brotherhood of Steel.
