Kokak's Hexen Page has a new version 0.8 of Kokak's OpenGL port of the publicly available Hexen source-code (which is based on the also publicly available Doom source). Word there is that since DoomGL shares its OpenGL engine with GLHexen (and GLHeretic), GLHexen could also support MD2 files (the 3D format used in Quake 2 for the objects) soon, just like DoomGL does. Also noted there, is that the ports on the page required Hexen 1.1, and don't work with Hexen version 1.0 or the demo version of Hexen. Thanks again Frans at 3D Action Gamers.
