I managed to get into the Beta by gamespot giving me a code and I thought the beta was fun to play plus the graphics and game play are great. The new feature that I thought was good was the kill cam. This shows you from first person how the enemy killed(if it was a great shot or just luck...now you be able to tell). Now, in COD 4 you get a ranking and you get it up by winning matches/getting kills. The higher the rank the more weapons you get. Matches have up to 12 people (in the beta) and are usually intense. So, COD 4 looks like its going to be a great game.
