Once you've completed the game, a few lines are added to your preferences.txt file, found in the game directory.

ModSystemEnabled = 1
Mod = none

These lines (at least the first one) are necessary to be able to access mods within the game. If you do not wish to finish the game before playing with mods, you can add these lines to preferences.txt manually.


To install a mod, you need to place the mod in the 'mods' directory. This is in a different place depending on your OS:

Windows (non-Steam): ..\darwinia\mods\
Windows (Steam): ..\valve\steam\steamApps\[username]\darwinia\mods\
MacOS: ~/library/application support/darwinia/full/mods/
Linux: ~/.darwinia/mods/

If this directory is not found where indicated above, you will have to create it manually. Make sure you maintain the proper file structure when expanding the zip/rar/otherwise-compressed file. Inside 'mods' there should be one directory with the name of the mod, and within that, should be game.txt and other relevant files and directories.

Some mods contain replacement graphics and 3D shape files that supplant the original game resources. If this is the case, then after loading the mod, restart the game to ensure these replacement resources are loaded into the game properly. If you're not sure if restarting the game is necessary, then do it anyways - it will only take a few seconds, and it won't hurt anything.

After restarting the game, be sure to create a new profile before starting the mod, otherwise the profile will be set to 'none', and your progress in the mod will not be saved.

If you have any issues with the game crashing or not starting properly after selecting a mod, then with the game shut down, open preferences.txt and set both of these lines to 'none', and restart the game:

UserProfile = none
Mod = none
