Forgot to post this here; a couple of weeks ago Cyan artist/designer Eric A. Anderson uploaded two proto-Uru proof-of-concept demos for DIRT (plus a non-Uru-related tech demo for the Plasma engine), posting links on his Twitter account. These are: • DIRT/Descent: A relatively long demo spanning from the Desert Canyon down the Great Shaft to the end of the Bug Cave. I've created a (miscellaneous) category for this and submitted a run for it; if you're reading this, you're probably already aware of that. • Hector Cove: A very small demo showcasing an early version of what would eventually become Noloben. I didn't create a category for this one, since there's not much in the way of gameplay, and there isn't really an obvious end point of any kind. • Nexus: The aforementioned pre-DIRT Plasma tech demo, created by Headspin to showcase the engine to Cyan, before their acquisition. Since it's not an Uru game at all, I refrained from creating a category for it. If people really want to run it, though, I could consider creating one (I'm not sure how likely it would be to be accepted as a separate game on this site).
