This game has a nice multiplayer setup, including maps. The biggest problem is campers and loud footsteps campers depend on to hide in corners to wait for you to run by. Campers have degraded my passion for Call of Duty - which I have been playing Call of Duty since it was called Call of Duty. Most folks call it tactical operations, I call it not playing the game to its fullest. Yes, when strategy dictates to camp, you camp (i.e. Search and Destroy, Headquarters). Otherwise, you are wasting bandwidth and oxygen in life. Play the game and keep Call of Duty fun and dynamic.
Tips: If you experience frequent losses in the one on one jump, verify your TV is game-friendly, use wired connections, forward ports, and get an energy drink or two to become a REAL Call of Duty player. Be friendly, respectful, and work the game out instead of CAMPING. In my honest opinion, campers reflect what they will become in life. Will you wait for success come to you, or will you pursue success and become the best you can be? Regardless of the intestinal fortitude, keep it respectful and "grow a pair." Play the game, don't let the game play you!
If I had to rate this game in multiplayer, I would score it a maximum of 5/10. Campers destroy the game folks! Make Call of Duty, camper-unfriendly for everyone to enjoy.
