Insomniac Games announced the release of the Marvel’s Spider-Man save transfer update. Once you’ve updated the PS4 and PS5 versions of the game, you’ll be able to transfer your save data from the original game to the remastered version.
To start transferring your data you need to start the PS4 version, load it up, and choose which saves they will import from within the game. As part of the export process, it automatically adds them to the PS5 version connected to the same PSN ID if you hit the right trigger in the menu.
Marvel’s Spider-Man Remastered is available for the PlayStation 5 with the Marvel’s Spider-Man: Miles Morales Ultimate Edition.
