Released in 2001 for PC and Mac, this main game blends Role-playing (RPG) elements with deep Turn-based Strategy (TBS) combat within the Fallout universe. You command a squad within the Brotherhood of Steel, focusing on tactical deployment, resource management, and unit progression through intense, grid-based missions. Its distinctive feature is the tight integration of granular squad control with character skill development, forcing players to master battlefield positioning to survive the irradiated wasteland.
