We’ve made the difficult decision to delay the full online multiplayer functionality within Sackboy: A Big Adventure. The team have been working hard to ensure that online is the very best experience it can be for players and we just need a little more time to get it right so you can enjoy it to the fullest with your friends and family.
Online multiplayer functionality will instead be coming via a patch by end of 2020. (Account for PSN and internet connection required.) This patch will also include:
Cross-generation multiplayer where PS4 and PS5 users can play together Game save transfers from PS4 to PS5**
