Black Ops will block party chat in some modes
Xbox Live socialistas were upset by Modern Warfare 2s policy of prohibiting players from taking part in certain online multiplayer modes while in a Live Party. In a recent interview with Videogamer.com, Treyarchs online director Dan Hunting explained that this policy returns in Call of Duty: Black Ops, reminding players that "we have that same restriction in certain playlists where they can use party chat to exploit the game mode." The hardcore Search and Destroy gametype is used as an example of where this would be appropriate.
However, the restriction wont be applied to as many playlists as it was in last years Duty, including Team Deathmatch and "any game mode where it doesnt make sense to have it." So, yes, certain game modes will still require you to converse with the hoi polloi, but isnt that part of the magic of online shooters?
