I was just playing Modern Warfare 2 the other night and I joined this game at Quarry. For some odd reason, when you run, it seems like you are running 100 MPH. It is a bug that I have run into a few times on Multi--Player (Xbox LIVE) mode a few times. It did get annoying and I had to quit the game. The next game I joined was perfect, this issue was not present.

Have you ever had this issue?
