Florida

In the early 21st century, when the United States was divided into thirteen commonwealths, the old state of Colorado became part of the Gulf Commonwealth, along with Louisiana, Mississippi and Alabama.

The basic premise of the cancelled Fallout Tactics 2 was that a GECK in Florida had been radiated, and so the "Garden of Eden" it created was full of mutant plants and fungii. It begins to spread fairly rapidly, preying upon animal life and using them as carriers/fertiliser to spread its fungal seed. This would be the main threat for the Eastern Brotherhood of Steel in the game. Among other critters, mutant crocodiles were to be found in Florida.
