Is Red Dusk on the Steam workshop? I did a search for it, but all I see is a Russian language mod by the same name.
No, they're still in development, although from what i can tell, they seem to be aiming for a release by the end of this year (possibly earlier??)
Mod got leaked on the workshop by some Furry Pedophile, Apparently this furfag (Who goes by the name Wicked??, not sure) had riled up so much shit, since he was doxxing people allegedly via false DMCA's, that
Paradox apparently had to intervene and got steam to term a few accounts belonging to him and his buddies.
The Russian Translation is of the leak, Whether or not the uploader is in with that guy or not is unknown, but it's seemed to either been allowed to stay up or just hasn't been taken down yet.
As i said, the leak ironically did more to help RD as they actually got quite a lot of people joining after finding out that the version uploaded to Steam was leaked.
You can kinda find traces of this whole debacle in the Red Dusk Discord, But to sum it up, Apparently this guy was going around stealing mods, editing them poorly and releasing them on the Workshop, Ice Cold etc.. were all run by this guy.
On top of also
spamming Loli Porn to people along with Gore, he would also launch false pedophile accusations against seemingly anybody, Red Dusk were victims of this along with the Fuhrerredux team, Age of Imperialism etc.. All of these claims apparently were forged screenshots using alts.
This guy has spent an autistic amount of time apparently doing this shit, which is evident if you ask literally any of the mods that were targeted as they seem to continue being harassed from time to time. The entire thing is a shitshow to read into.
TLDR; Russian Translation is Unofficial, Furry Pedo did too much autism and got Paradox's Attention
As stated, it's something that can be traced and you can find all sorts of shit in regards to this debacle.
