Aww yean, they are here: Ken I hope you can bring us some nice map, i have a couple ideas but you'll have to work 'em out
P-Body and Atlas have a "face", well actually it's just an eyeball and a piece of metal but the emotions in it are AWESOME. And in Portal2 the only characters are Chell (can be seen normal), Cave Johnson and Caroline can be seen on a portrait, so no Face poser is really needed. But who knows, maybe somebody would like to see a mod with other persons? (co-operative testing with 2 humans instead of robots).
