I've released a very early prototype of the game here: It's to be a free, Modified BSD licensed, content replacement for the Hexen engine, very much like Blasphemer is for the Heretic engine and Freedoom is for the Doom engine. Currently the WAD contains a few textures, sprites and sounds taken from Blasphemer. Currently, it's possible to start it in ZDoom derived Doom engines, but isn't playable because there's no maps in it yet, thuogh it's possible to start Hexen PWAD addons with it. Any kind of contributions would be greatly appreciated.
