A GSC file may also be a scene file used by a 3D Groove Engine video game. It contains binary data used to load a scene and included in-game objects. GSC files are comprised of compiled Lua scripts and a custom header.

More Information

The Groove Alliance and other developers used the 3D Groove Engine to create many original and licensed games.
