Essentially everything. Music, controls, graphics, all work well.
What does not
Mouse control is a bit flaky. Clicking does not always make you start shooting.
Side note: I used a laptop touch pad. It may be the game itself having issues with the pad.
What was not tested
Victory, though I don't think it truly exists in the game.
I am using Wine 1.1.42, which is not listed in the version drop down menu. Other than the mouse mode problem, there was one other oddity I encountered, upon exiting the game, I had to log back in to Ubuntu, and none of my opened windows were still there. It was as if I had just turned my computer on.
