Urban Terror was just updated to another version and also offers another Anticheating software, Battleye. I'm not sure if I made the patch correctly, it also adds to .xpms.
A forum thread explaining what the changes are with full source:
Battleye + Urban Terror 4.0 support
Logged In: YES
The author should send the unified diff to the mailinglist so it can be discussed. I don't like a special flag for specific anti cheat techniques. I'd rather replace the punkbuster icon with something generic.
the gametypes are in svn meanwhile. Battleye is dead. closing.
