The mutant warehouse was set to appear in the canceled Fallout movie.
The main storage area for the mutants led by the Master, it was filled with everything they had pillaged from the various southern Californian vaults over the years. Max was taken here to be given a defective G.E.C.K.. The mutants stationed here were then eliminated entirely by Max, and he then had access to their gigantic storehouse of equipment and weaponry for a brief time before he had to free Hero and his team and then flee the Hub.
