I also believe it is a fork of Warsow as you say. But I am not so sure if Warsow has any players today and I admit I didnt invest enough of my free time to find information about Warsow. Thank you for pointing to that. If someone is reading this wants the information on Warsow here is another link https://warsow.net/ . I will try to edit my first post and mention Warsow and Warfork together. I hope I can fix that.
Is AstOS still active? I found this AshOS which is similar but I had never tried any of it. Maybe also inactive don’t really know. Thx for mentioning AstOS, I never thought this is possible on Arch distribution.
