Floodplains
A 256x256 sized map which is a modified version of the recommended plains map. This map has some additional randomization of resources, and new water flow zones which are less reliable.Simply place the .timber file into your \Documents\Timberborn\Maps\ folder, if you have downloaded this manually.
If you have downloaded this through a mod manager such as r2modman, then the program should already have done what is needed for you to load this map.
