This is a work in progress. We already know it's buggy.

Shadow Warrior runs natively on Linux now, thanks to 3DRealms releasing the game source.

What works:

???
Sound

What doesn't work/known bugs:

Nearly everything.

To use:

Don't yet.
If you must, grab the source from SVN (webview).
svn co svn://svn.icculus.org/shadowwarrior/trunk/ shadowwarrior
You can even download a basic sw.cfg file: sw.cfg

IF YOU HAVE PROBLEMS:

Tough luck. Do NOT contact us with bug reports at this time. Do NOT contact us if you can't get it to build. Do NOT contact us for copies of the game. In fact, if you aren't sending us code, don't contact us at all.

The 3DRealms Forums might help you, however.
