I'm sure most people have completely forgotten about this mod, figuring it to be vaporware.
Luckily, that's not the case. Some of our team have been picked up to develop a game similar to OW:Z for the retail market. That's right, we're getting paid to make games now!
So while I can't release any new media or even divulge what exactly we're doing, if you're jonesing for some 6DoF action on the Source engine, you'll get it sometime soon. :)
