This modification is basing on old Winter Mod (mainly Newworld). Update is heavy: many changes in textures and vobs and moreover now winter is also present in Oldworld and AddonWorld. Christmas 2020 release.
1. For this mod to work GothicStarter (from PlayerKit) is required*.
2. Just unpack everything from .rar to your Gothic II folder.
3. Launch GothicStarter and chose Complete Winter mod.
*However if you dont have GothicStarter and still want to play the mod, you can rename file COMPLETE_WINTERMOD.MOD extension from .MOD to .VDF and then place the VDF file into Gothic II/Data directory and launch Gothic2.exe
