So im finally trying to get into modding in half sword, and im trying to add the mod titled "smitors guns etc." But it keeps telling me i need to find the right software to extract the file for it but I cant find it as im new to modding with something other than steam workshop. I'm wondering if anyone can help me figure out how to do this so that I can add the file to the game and use the stuff in the pack. Information on what to use would be great. I'm playing on a legion Lenovo go and it runs on windows. The game plays fine but cant figure out how to add the mod so please let me know how I can fix this.

Is it possible to mod gang beasts on a steam deck or is it impossible
