Query: a XBOX LIVE must title!!!

If you have XBOX live and you love FPS games, this game is a must. This game is even more addicting than it's counterparts UT and UT2k3 on the PC. With UC and LIVE, you can communicate by voice to your teammates. Great visuals and fast addictive action is what to expect when you you take this game online!
