Turrican2K as updated his http://turrican2k.sourceforge.net/ with this news:

I just realised today that I never released the Katharsys Genesis demo anywhere apart from on DCAnthology (in which the images didn’t work 🙁 ). This weekend I’ll release (hopefully):
-Genesis Demo
-Project Katana Alpha 4
-Screenshots of the first game on the 3D engine.
