Sony has published a new trailer for an upcoming feature, Share Play, which is coming in their system 2.00 update to the PS4.
Featured above, you can watch the video walkthrough for the new feature, which lets you or your friends watch each other play games, take control of said game (to help them beat a tough area), and even lets you join them in multiplayer—regardless of whether the second person owns the game.
Version 2.00 is hitting Playstation 4 this coming Tuesday, October 28th.
