the 2.0 is really bad. enjoy the original from here: https://blueflare.assassinate-you.net/
Mint version is outdated, and the game tells you that you need to install a more recent version to be able to play on official servers... so I got the latest version from their site... works good on Mint.
Great game, but marred with problem on Mint - unplayably low framerate, and very buggy procedyre for changing screen resolution.
