The ruins of Boise, Idaho are awash with ravenous mutants and brutal Super Mutants of both the east and west coast variety, not to mention deadly creatures ranging from Mole Rats to Radscorpions. But what makes the Boise area the most hazardous are the various raider gangs who team in the hundreds. Constantly fighting one another and the abominations that infest Boise, the gangs of Boise have become tough and hardened killers, crazed and merciless. Some, such as the Boise Boys, have become forces of such might that they may contest other factions such as the Idaho Brotherhood of Steel, while others are merely groups of savages that have managed to cling on to dear life by scavenging and robbing where they can.
