Fort Worth is a Brotherhood of Steel outpost in Texas.
It is overrun by the Jackals, a savage raider clan equipped and sent there by Reese. Cyrus is one of the few Brotherhood survivors, and is eventually killed by Banshee, the leader of the Jackals.
When Banshee is defeated, the player character threatens him to give him the key to Vault 39 in Lone Star. But before he can tell who is behind it all, he explodes.
Fort Worth was to appear in Fallout: Brotherhood of Steel 2, the canceled sequel to Fallout: Brotherhood of Steel by Interplay Entertainment.
