The latest Hack and Slash Computer Game release is for developers only. It requires Blender to run and/or modify. It does not use any version of the Quake engine, but uses the Blender game engine instead. In some ways it is more advanced than the last stand-alone quake-based version we released (multiple player for one computer,) and in many ways it is less advanced.
(It is not develped enough for players - if it was, we would have included a stand-alone version that did not require Blender to run.)
