Regional Modification: A modification file for Cataclysm: Dark Days Ahead.

How to install this mod:

1. Extract Regional-Modifications_master.
2. Put regions to the json folder of CDDA.
3. Done. Enjoy your new surroundings!

How to apply this in a world:

1. Create a world.
2. Finalize the creation.
3. Play that world with any character, then Save and Quit to go back to the Main Menu.
4. Play that world again. At this time, go to Settings.
5. Go to the World Options.
6. In the Default region type, you may change its value.
7. Once you have selected a Default region type value, save it then Save and Quit.
8. Go to your worlds and reset that world.
9. Now, create a character to play that world.
10. Done. Enjoy your travels!

Well, its a bit complicated due to a bug that you can't fumble the Default region type unless you have loaded all the necessary files through playing for the first time you opened the game...

Additional Info:

Go and read the README.MD inside the regions folder, available regions and their specialties are listed there.
