Ratchet & Clank (2016) is now free-to-play for PlayStation 4 & 5 players now until March 31st, 2021! It is part of their “Play At Home” campaign, which is supposed to encourage people to stop spreading Covid-19. That being said, you should be able to go into the PlayStation store and download it without questions!
Ratchet & Clank (2016) is based on a movie that came out during the same year. Personally, I don’t know too much about the game myself, but I played it when I was younger! Looking at the gameplay, I’d actually play this today if I could.
