I was looking for this mod. Thanks.

Thanks for the explanation!

@Unruly The thing is that the mod you are mentioning is only able to change the volume of a sound in the game.
Thats not quite the same.
My Mod actually completely changes how the Hydrogen Thrusters Sound in general instead of just turning down the volume.

Not to criticise, but there are sound mods already that address this sort of thing, no? Like configurable parameters

You do need to also install texthud api and rich hud terminal, but they're pretty light and (afaik) server friendly since they're client side only.
