Unreal Tournament 2003 Mac OS X
MacGamer reports that Unreal Tournament 2003 was shown at MacWorld San Francisco:
The first-person shooter is currently in development for the Macintosh platform and was being shown in nearly complete form at the show. Epic Games indicates it is deep in beta testing and is expected to be completed for a first quarter 2003 release.
Apparently, UT2003 OS X was in good enough form for daily tournaments at MWSF.
