Behind the scenes
This challenge is a reference to the original Fallout and Fallout 2, as all of these weapons, except the Bozar, could be acquired by the Vault Dweller, whose home was Vault 13 and who faced the threat of the super mutant army. The Bozar can be found in Fallout 2, where it can be used against the remnants of the Master's Army.
