Starting today, you will be able to stream as well as download PlayStation Now games to your PS4 system so that you can play both locally and offline, all with a single subscription.
Sony announced that almost all PS4 games in the service, including Bloodborne, God of War 3 Remastered, NBA 2K16, and Until Dawn, will be available for download, in addition to the PS Now lineup of classic PS2 games remastered for PS4. This feature will be gradually rolled out to PS Now subscribers over the next couple of days.
Downloaded PS Now games will support all user-purchased DLCs, microtransactions, and add-ons, as well as PS4 Pro enhancements for subscribers using a PS4 Pro system. You do not need a PlayStation Plus membership for online multiplayer on PS Now - which stays the same for both streaming and downloaded games.
If you've already started a game via streaming on PS Now and want to continue playing locally on your PS4, you can transfer your save file from the PS Now cloud to your console with a PS Plus membership (sold separately). This is done by transferring the save file from the PS Now cloud to your PS Plus cloud storage, then transferring it from the PS Plus cloud storage to your PS4 system.
Note that you will need to connect your PS4 system to the internet every few days to verify your PS Now subscription, even if you're only playing downloaded games.
