Fluffy's working on the humans as part of his mod, but I don't really know anything about it. They're not a part of GLADE's project anymore, so you'll have to ask him if you want to help with that. I think I'll do the vehicle tonight myself, since I just got a really good concept of it, and I'll PM you the files and the two building concepts. (Yeah, it's two now.)
