Introducing a new Steam feature that lets you play your couch co-op games with friends over the internet, together.
Now in Beta! With Remote Play Together, you can now invite Steam Friends to join your local co-op, local multiplayer, and shared/split screen games online. Up to four players,or even more in ideal conditions, can instantly join in the fun. Only the host needs to own and install the game, while additional players connect through Steam Remote Play streaming technology.
Matchmaking Update: == - Immortal players can now only party with Immortal or Divine players in Ranked. - Immortal players will only ever be matched with other Immortal or Divine players in Ranked. This means, for example, that if there is a Divine player in a party with players below Divine, that divine player will as a result never end up in a match with other Immortal players.
