If you start playing MW3, you can hit 'A' on a second controller to play with you split screen on live.
Also, you can hit 'Y' and invite friends, making a party through some games.
Are you able to do these two things together?
Moreso, I may want to do private party chat through Live versus in the game.
When starting the game back up, after joining in a party, the option to hit A was not there.
Is there a way to be in an xbox live party and have a guest join in on the game?
Best Answer
You can be in a party while playing split-screen, but unless the second player has an Xbox Live account, they won't be able to participate in any of the voice chat options that Xbox Live offers. You can plug a headset into their controller, but they won't hear the party/game chat audio, and their mic won't function.
If the options to join a party aren't on the same buttons in-game when you're playing split screen, you can always use the Xbox Guide button to access the party menu and start/join a party from that interface.
Note also that you have to have a second controller plugged in/turned on in order for the "Press A to Join" message to appear in most games (MW3 included). There's nothing in MW3 or Xbox Live that prevents you from doing both at the same time.
