yes Brahmin is definately a change I plan to make, if you look closely you will see (i think it was added in fury road) that they have the classic two heads
as to your other suggestions, nice ideas, but I have no idea how
Fallout(radiation) is basically an impassable terrain type so that would not necessarily work with a crater, you can get radimmune promotion which lets you move through these tiles, but I would also have to learn how to add it in the map script and make craters spawn with fallout.....?!?!?!?.......
I do plan to add a lot of resource types in the future, all your favourite fallout types.
for now just consider all water contaminated, I do want to do something with this, I just don't know what yet. also consider populations to be much smaller than they are...sadly you just have to use you imagination with me, till I can learn how to do this properly!
were you able to integrate the new file ok? it goes in Fallout Tame THe Wastes/assets/XML/gameinfo, and let it replace the existing file... I hope it will solve the problem... if it does I will reupload the main folder.
