Migter12 TeleCreeper I am also having an issue with getting the mw2 sounds mod to work. I tried doing fs_game mods/mw2_sounds in the console. This sets the fs_game dvar to mods/mw2_sounds (which I have the mw2_sounds folder placed in), but the gun sounds did not change. I've tried running this before starting a private match, and during a private match, but neither worked.
UPDATE: This was actually fixed around December 2024 from a Plutonium update regarding client-side mods.
