[quote]Chat Settings: Proximity - Chat with players near you. Fire Team - Chat with your Fire Team. (A symbol appears above your head to non-fire team members which indicates that you cannot chat.) Off - You can't hear anyone in-game, nor can they hear you. (A symbol appears above your head to all players which indicates that you cannot chat. This setting would also be activated upon joining an Xbox LIVE party and whatever the similar chat system is called on Playstation consoles.)[/quote]
