The Unknown Hero is on hold due to lack of money for living with, lack of portrait artist, and lack of a scripter. I had been trying to learn how to do portraits and scripting myself however the lack of money has now made that impossible for now.
However, the introductory in-game cutscene is now released so that you can see something of what the game was planned to be.
See
http://www.theunknownhero.com for more details on the release.
You cannot move around in either the first or second "module", the second one is merely so that the cutscene works properly and has nothing to do with the game, and the first only has the cutscene. (There is a team-only release featuring the first quest however that is buggy and unfinished, and the spells are not integrated into it.)
