We are slowly starting to send Human Error to playtesters, as the only things missing are the few lines by one our actors, and the music. I have started the Super Secret Beta Testing Blog to give updates about the progress of bug finding and fixing as well as the general development of the mod, as we are closing in to release. Right now we are hoping for a January 2010 release, even if it requires going into the crunch mode.
We are also looking for some help to finalize the mod. Mostly the music department, including a "Human Error Theme". If you are interested, post on our Moddb forums.
