A Shapes Shuttle that allows editing M1A1 maps in Forge. Example maps and the M1A1 Physics model are included.

Marathon's original soundtrack re-recorded with a hardware synthesizer instead of QuickTime's software synthesizer for a more realistic sound. This is how Alexander Seropian's compositions should sound if played with real instruments.

This is an absolutely spectacular "Space" landscape replacement for any Marathon Shapes file, in full and living COLOUR! The shot is a colossal sweep of the cosmos, as photographed by NASA.
