Party chat has always been a feature that was, unfortunately, only available on Xbox LIVE. That exclusive perk, however, is over, as party chat has been confirmed for the PlayStation 4.
This PDF file confirms the cross-game chat feature on page two in a section called “shared game experiences.” Sharing is a big part of Sony’s PlayStation 4 philosophy, as evidenced by the fact that the controller has a button called share . Here’s a snippet:
“PS4 also enhances social spectating by enabling gamers to broadcast their gameplay in
real-time to friends using live internet streaming services such as Ustream. During live
broadcasts, friends can make comments on the streamed gameplay and, if a gamer gets stuck
on a challenging level, friends can also join the game in completely new ways. For example,
friends can offer health potions or special weapons when a player needs them most during
actual gameplay.
Furthermore, users can connect their Facebook account with Sony Entertainment
Network account. Through PS4, users are able to deepen their connections through co-op play
or “cross-game chat”.”
