By saying modified version ?
Larian studios wanted these files to be modified by us thats why they created a public folder.
When we decompress game files by pattern codes and put them into public folder so game initilaze to look
at these files that we coded first in runing whats we called modding. Normally Modders will wait for game's original
modding tools to make things easy and more friendly.
However some of us started before to make exercise and create new ideas to be tested before
modding tool released.
Main campaign will be changed by modding this way.
