Not sure if the Nightdive devs are active here like they are on the Steam forums but if anyone from the team browses this forum, is it possible that after the Windows version has had time to mature and have all the issues ironed out that a Linux version will follow? Most other Nightdive games have eventually been ported to Linux after the initial Windows release so that would be amazing!

Nightdive are not active here at all at least on the Blood side of things. I mean we are still using the original games forums we didn't get nice new ones for the new version. Steam did, they also get official patch notes and someone from Nightdive replying to a select few. But yes their communication on both stores could bet better. Anyway to answer your question:

Linux and Mac versions are on the way. They posted that much in their official Discord. Anymore than that we don't know.

I bought Fresh supply it has a linux version in the goodies tab

That's the original version that uses DOSBox.

I know it isn't that helpful, but B:FS does work using Wine on Linux. I had trouble getting it to work on Mac, but that may just be a Wine configuration setting I am missing.

As a Linux (Mint) user I'm looking forward to a Linux native release of Blood Fresh Supply. The DOSboxed version ain't bad, but I'd prefer the new version on Linux.

How'd you get it working through Wine? I'm trying to run it through GOG Galaxy but I'm getting Error message telling me that "Exception caught in main: see CRASHLOG.TXT for more info"

I just did it as a test, but this is what I did:
Fresh install of Linux Mint 19.1 (cinnamon with third party software)
Installed Wine (stable) through the software manager
Installed Wine GUI front-end "Playonlinux"

After that was installed, I ran through a wizard thing with Playonlinux and just pointed it to Anuket_x64.exe as a program (copied my B:FS folder from a Windows box), not an installer. I didn't try it through Galaxy.
