The FreeSpace 2 Source Code Project is the project of a group of programmers currently maintaining and enhancing the game engine for the space combat simulator FreeSpace 2, developed by Volition, Inc. You will need the game data from FreeSpace 2. If you don't already own FreeSpace 2, you can buy it from online stores such as Steam, Amazon or GOG. Copy the data directories and all .vp files into ~/.fs2_open for the game to work. Notice for Intel cards: You may need to export 'MESA_GL_VERSION_OVERRIDE=3.2' if the game doesn't run.
