It seems the PlayStation 5 is the gift that keeps on giving as players have just uncovered a new feature hiding in plain sight for Sony's next-gen superstar. As the PS5 muscles into the already crowded console market, it's the end of an era as the fan-favourite PS4 bows out. You've given us some great memories with the likes of Red Dead Redemption II, Marvel's Spider-Man, and God of War, but all good things must come to an end. That doesn't mean you should simply chuck out your beloved games. Thanks to Sony finally expanding on its backward compatibility, the "overwhelming majority" of PS4 games can be played on your shiny new PS5. Sony and Microsoft are locking horns with their next-gen systems, however, the PS5 is once again edging ahead of the Xbox Series X and Xbox Series S. With the PS5 being able to play upgraded versions of some classic PS4 games, the PS5 upgrade feature will now warn you if you're about to play the PS4 game.
