A post on PlanetUnreal describes the Unreal Mission pack as having just gone gold (off to duplication), citing the Wheel of Time page as the source of the information (Legend Entertainment is behind both projects). Thanks Vængr3I=. When checking the WoT page, however, I cannot find the update to which they refer, so the post may have been pulled, which may mean there is a problem with the accuracy of this story (Update: the update is back on the WoT page, it seems there was just a temporary glitch). Here's a portion of the update:

First, even though this isn't strictly WoT-related, I must congratulate the Unreal level pack team on a job well done. They went gold over the weekend. While the pack may appear to dwell in WoT's shadow a little, there's no question that it represents a significant milestone in Legend's history. Heck, our last release (and most of the titles that preceded it) was a strict adventure game. The Upak represents our first shipped product in the FPS genre. My hat is off to everyone who worked on it; the end product shows a lot of time, effort, and long nights filled with superheroic tales of hostess advertising.
