Good game, but outdated. Many people says 2.0 is bad, and if you also think that way, please use this. Otherwise, go to official website.
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Mint version is outdated, and the game tells you that you need to install a more recent version to be able to play on official servers...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.
