      Urban Terror is a free multiplayer first person shooter developed by
      FrozenSand, that (thanks to the ioquake3-code) does not require
      Quake III Arena anymore. Urban Terror can be described as a Hollywood
      tactical shooter; somewhat realism based, but the motto is "fun over
      realism". This results in a very unique, enjoyable and addictive game.
