I am thinking of buying this game for playing multiplayer with a friend on xbox live. I would have no interest in the single player. I have played CoD5 WaW with said friend on xbox live always in party chat and I have heard this game does not allow that in multiplayer. Is it worth getting this game to play with this friend online or not?
Yes. Although party chat is not allowed in most game modes you can have party chat in Mercenary Team Deathmatch and a few others that I cant think of. Dont let this put you off buying this game because you will have a blast. There is a way round this though, Select your Profile, then Edit Profile and then select Privacy Settings. Select the Voice and Text menu and choose Friends Only. You'll now only be able to hear people on your friends list during any Modern Warfare 2 game type, and only your friends will be able to hear you.
