Summary        : A team-based tactical shooter based on the Quake 3 Engine
Description    : 
    Urban Terror can be described as a Hollywood tactical shooter;
    somewhat realism based, but the motto is "fun over realism"
    which results in a very unique, enjoyable and addictive game.

    This package contains only the engine including the dedicated server.


This bug is very similar to bug #1183104. It looks like both games use the ioq3
engine.
