How to add friends

I'm on XBL and you're on PSN i don't think you can add me through PSN .More likely  you'll need to add me within your origin client  program you'll have to install it on PC , because as far as i know you can't add friends/contacts  from origin internet page .

I don't know if its worth a hassle , but you can try :D 

But if any of your PSN friends play MW then game will show them on your Most wanted list .
