The Ratchet & Clank PlayStation 5 update announced earlier this week is now live worldwide, introducing 60 FPS support on the current-gen console.

The update going live today is unexpected, as it was originally announced for an April release. The game is currently available for free as part of  Sony's Play at Home initiative, and it is also part of the PlayStation Plus Collection so there are multiple ways to enjoy it for free.
