Building the final temple / boss stage at the moment. Perhaps one if the biggest you ever seen in Unreal Tournament.
I hope can squeeze this in the CM4 Main map along with the other parts, CM3 is huge, CM4 is going to like gigantic-titan-huge. I am sure it will all be worth in the end when we are all playing the final edition.

There is going to be water everywhere, but I'll do that at the end.
All walls that have the current brown stone texture, will be black just as CM3. To enhance, and make more vivid/bright colours. Here is a mylevel-test-map-screenshot. Current colours aren't definitive but, It creates a pretty cool effect:
