From what I've heard, that bit at the end of Descend was never a song in the first place and Andrew asked him to make a full version for Jade: Enter, so Umbral Ultimatum IS the full version.
I could have sworn he mentioned it on his blog and even gave it a name at one point but I couldn't find it under the "music" tag and I'm sure not wading through 100 pages of Radiation rambling. Maybe I mistook it for something else but I was pretty sure when Umbral Ultimatum came out people assumed it was the full version and Radiation said no? Ugh I can't remember. Jesus H. Dick, Jade: Enter happened a little over a year and a half ago. :|
