Just learned of his game. Looks pretty damned good. http://pc.ign.com/objects/818/818215.html I really like the vids they got up. This game looks like it'll be VERY intense. Hope it's offered along with the rumored Portal v2 in the next Orange Box (Black Box?)
Saw the preview in EGM. Looks sweet and thy concept is awsome. Its just always hard for games like this to have games played like the developers intended though.
