The Gulf Commonwealth

The Gulf Commonwealth was one of the thirteen commonwealths of the pre-War United States of America. Created in 1969,[1] it was comprised of the former states of Louisiana, Mississippi, Alabama, and Florida.

Former FloridaEdit

Mini-FOT2 LogoThe following is based on Fallout Tactics 2 and has not been confirmed by canon sources.

A G.E.C.K. had been irradiated, and thus, the "Garden of Eden" it created was full of mutant plants and fungi. The mutant garden began to spread fairly rapidly, preying upon animal life and using them as carriers/fertilizer to spread its fungal seed. While it had accelerated regrowth and nature reclaiming the wasteland, the fact it was irradiated meant it also began to wipe out humans. The Midwestern Brotherhood of Steel had also gained a foothold in Florida. Mutant crocodiles were some of the forms of regional wildlife.

Former MississippiEdit

Not much is known about this area other than a pre-War military supply yard that existed somewhere in the former state. It is mentioned in General Brock's terminal at Fort Strong as being a location where the new model M42 Fat Man launchers were sent. The warheads were supposed to ship at a later date, but never made it due to the Great War.


The Gulf Commonwealth was to appear in the canceled Fallout Tactics 2, and locations within it are mentioned in Fallout 3 and its add-on Point Lookout, as well as Fallout 4[2] and its add-on Nuka-World.[3] Florida was also the setting of Fountain of Dreams, a follow-up to Wasteland.
