If you can somehow get ahold of this dude and convince them to hand over the game they're completely abandoning I would gladly be willing to spare some time to help on developing updates for it.
Unfortunately, they seem to hide behind Kziko 100% of the time, I've never seen them interact directly with a member of the community in my 1+ years here.
Also, if you want them to ever consider handing over the game you all have to stop showing interest in these scam private servers they are offering. The service being offered for the private servers is that Tatrix literally boots it up and never touches it and you're just screwed if anything goes wrong. All this person wants is money and if you do not give them that money so easily, maybe the game can be saved.
I'm probably gonna be banned really quick after posting this, hope people see it.
