This mod will prevent the game from launching on Linux because it cannot find certain files. The files in question do actually exist, but the Linux file system is
case sensitive and the files have names that are not EXACTLY what the mod is looking for. Luckily, it's only a few and it isn't too much trouble to rename them manually to get the game working. The files in question are located in the mod folder under graphics/tahlan/maps/weapons_normals/
- tahlan_percale_cover_r_Normal.png
- tahlan_banshee_cover_1_Normal.png
- tahlan_banshee_cover_2_Normal.png
- tahlan_banshee_cover_3_Normal.png
Just rename these files with "Normal" lowercase, and it works.
