Just a quick note for those wondering if it plays in Wine I've found that you need two dlls to get it to work I think you'll find them in winetricks or grab the direct x full installer and have the full fun of hunting in the cabs for those that like it the hard way.

D3DCompiler_43.dll and X3DAudio1_6.dll are the files you want. Haven't played it after checking the release version so how stable it is compared to playing on Windows I don't know.
