So today Call Of Duty: Modern Warfare Remastered went on sale as a standalone product, despite Activision once saying it would never happen. At the moment the game by itself costs £34.99 on the PlayStation Store. Those of you who had access to Modern Warfare Remastered after buying the Infinite Warfare Legacy Edition may think that with recent developments you wouldn’t need the disc anymore. You’d be wrong as Activision has clarified that version won’t work without the Infinite Warfare disc.
Hi. The existing Legacy Edition of IW will remain unchanged. You'll need your IW disc to play MWR. ^DL

So if you thought you could trade in your disc of Infinite Warfare but still play Modern Warfare Remastered you’re out of luck. Maybe we’ll see a change down the road.
