I have big news and some pictures. While not my choice the team has FINALLY decided on Unity. HOWEVER; Thanks to Pacmikey my work in Source will not go to waste and will be instead be ported to Unity. GHz and roxies (Yes his name is not capitalized) will work on the code once the pre planning phase is finished. I'll still be posting screenshots from Source as they look a lot better visually than Unity even in this early state. Here are pictures of the crawl spaces.
