H – Immersion

Somewhere in the ocean, a submersible is launched from a research vessel. What mysteries will it uncover? What worlds linger underneath, waiting to be awaken? Take a dive into the deep.

H – Immersion is a 64kB intro. What you see and hear fits within a single 64kB Windows executable binary. Textures, 3d models, music, animations and other effects are generated at runtime.

The code was written by Julien Guertault and Laurent Le Brun. The music was composed by Daniel Lindholm, using 64klang (a synthesizer created by Dominik Ries). The binary is compressed using kkrunchy.

A first version was presented at Revision 2017 and ranked 5th out of 10. The final version, with a different ending, was released in December 2017.
