Seriously thinking of installing the newest Linux Mint on my desktop so I can play this again. Installed it on the Laptop and it plays. I think I read about an issue with it playing on the Ubuntu version this is based on. Installed a similar style game…Nexuiz which mostly works. The cursor is trapped within the bounderies of the game and Quit doesn’t work. I can Ctrl+Alt+Tab to leave then kill darkplaces in the System Monitor.
