The Xbox 360 version of Modern Warfare 2 won't allow gamers to be in Party Chat while playing the game, according to a screen uploaded by a NeoGaf poster.
That means that gamers on different teams won't be able to cross talk and cheat. Of course, it also means that gamers won't be able to chat to friends not playing Modern Warfare 2 while they're in the game.
The PlayStation 3 doesn't have a cross-game chat capability.
While some people seemed upset about this move, I think it's a pretty good idea and will help cut down on people giving away positions in ranked matches. Of course, someone could just pick up a phone if they really wanted to cheat.
We've contacted Activision to try and confirm this screenshot.
