Hello, I also played this game and really loved it, I think our best bet is to look for their indonesian server
https://www.megaxus.com/
that page had the last version of dark blood ever, they published until 2017 I think, under the name of Heroes Of Atarsia
They no longer have the game avaiable but I bet they still have the server information?
I do have the installlers for the english steam version, the brazilian version, Chinese version and the indonesian version.
But they are just that, installers, you can not log to the game nor execute them, it would be nice if this game could revive, you can visit a post on ragezone, there has been some progress for information.
