For one, players will be able to use their smartphones/tablets as a second screen for gaming (for games that support such a feature). The apps will also make it possible to login to the PlayStation Network, chat with friends, watch gameplay videos (and live streams), and more.
Finally, the apps can also be used as an additional controller for games, although it’s unclear how many games support this feature. Sony has previously announced that PlayStation 4 games will support Vita cross-play — in fact, pushing PS4 gameplay to the Vita is mandatory for all PlayStation 4 games.
The PlayStation 4 launches on November 15 in the US and November 29 in Europe. The apps are expected to be available around that time.
