The DM-Morbias for UT (@utgame) made by Jim Brown was supposed to make the 5/28 build but slipped through the cracks for some reason. For the impatient types like me, you can play it online on the Unreal Carnage HUB under the “DM All Maps” gametype.
One reason it might not have gotten into the game is because it was misspelled as “DM-Morbais”. Doh!
