I just tried playing this two days ago. Getting it to run was not good -- somehow I could only get past the main menu by loading the game through Gamescope. But then in the mission planning phase clicking around to plan anything just didn't work. So the best I managed to do was finally load into the game, turn around and friendly fire my tier 1 operators, and then leave the game.
Typically, I have very good luck with old games from this era with Linux+Wine. But this one was a bit too busted. There's probably still things I could try, and maybe I'll revisit it today.
