When the PlayStation 4 was announced early last year, one of its most advertised features was the ability to let online friends take over each other’s games without being in the same room. That feature is finally set to become available later this year.
Dubbed “Share Play”, the feature is compared to being a “virtual couch”. For example, if a friend is playing a game, he or she can stream the game over the Internet, and allow the ability for another friend to take control of the gameplay over the network regardless of if they own the game or not. In addition, Share Play will also have the ability to stream local multiplayer gameplay online, with the player joining the game essentially being recognized as “controller two”. Share Play will be introduced in system update 2.0, alongside YouTube video upload support.
The 2.0 update will be available this fall.
