Substream is an abstract 3D shooter, synchronised to music. Every level in Substream is individually crafted to closely follow a piece of music. Enemy attacks are choreographed to the sounds of individual instruments. Your weapons move to the rhythm. The ground below you vibrates to the melody and reforms when the mood changes. Substream aims to bring a new degree of synchronicity to gaming. Substream will feature a variety of music from metal to jazz, and hip-hop to chiptune. It's due to be released sometime in 2011 for PC, and maybe some other platforms.
