As you know, I still play CoD4 from time to time but the recent spam messages and map glitch has turned me off until a fix is released. So, someone other than me has asked the same thing and the reply was:
OGxKushington:COD 4 is my favorite Call of Duty im in a TDM and guys are flying around the map i guess we can expect this for Mw3 as well?
Robert Bowling: No sir. COD4 doesn't have the same security as our latest games and hasn't received the security updates yet. Still supported
The statement in bold made me laugh.
bbexperience: "hmm. I don't know. It's hard to notice the sensitivity of the sticks when the controller is flying through the air."
