Taking place in a time period between the two PC games (Fallout 1 and Fallout 2), this action-RPG based on the Dark Alliance engine sees the player character join the Brotherhood of Steel, a band of vigilant humans seeking to maintain peace in the now trademark grim post-apocalyptic world. The player's team finds itself instantly engaging in battles with raiders, mutants and a bevy of radioactive nightmares using a mixture of 50 different up-close melee and ranged weapons. Gamers can get right into the mix in the single-player, story driven game, or if a close friend is at hand, both can start up a co-op game to play from start to finish.
