Mac OS and Linux offering OpenGL graphics and effects, advanced 
Multiplayer, many improvements and new features.

You will need the game data files to actually use d2x-rebirth, 
place these in /usr/share/games/d2x-rebirth or ~/.d2x-rebirth. 
Details of how to extract the correct game files are in the file

consider downloading the enhanced soundtrack 'AddOn pack' from
