Although scheduled to be released sometime in 2004, EA cancelled the project on June 30, 2004, after the closure of Origin and the layoffs of several employees. Despite being a multiplayer game, UXO was being marketed as a continuation of the Ultima series that was last visited with Ultima IX rather than as a sequel or replacement to the still commercially successful Ultima Online. Although the "X" in the title is a Roman numeral 10 (in keeping with its place in the sequence of numbered Ultima games), it is sometimes pronounced as "eks," instead of "ten."
