Activision has updated the Call of Duty: Modern Warfare Remastered FAQ to state how players on PlayStation 4 that are currently playing the Call of Duty: Modern Warfare Remastered campaign can access the full, final game on November 4.
Regardless of how you purchased the game, the early access period ends on November 3. All of your progress made in the early access period will transfer over.
If you pre-purchased select editions of Call of Duty: Infinite Warfare at a retailer, once you go back to the retailer on November 4 to get your disc, you must re-download the full, final version of Call of Duty: Modern Warfare Remastered that will grant you access to the campaign and multiplayer. As noted before, for physical disc customers, you must insert the Infinite Warfare disc in order to play Modern Warfare Remastered.
In preparation for the global launch of the Call of Duty: Infinite Warfare Digital Deluxe and Legacy Editions featuring Infinite Warfare and Modern Warfare Remastered, your access to the Early Access period of Campaign mode in Modern Warfare Remastered will end on November 3rd prior to launch on November 4th. Once you’ve picked up your disc-based (physical) Legacy or Legacy Pro Edition, you will be required to download the full version of Modern Warfare Remastered, which will restore access to Campaign and include Multiplayer.
For those who have purchased the Digital Legacy or Digital Deluxe Edition of Call of Duty: Infinite Warfare on the PS4 Store, no later than November 4, Call of Duty: Modern Warfare Remastered will receive an update to unlock the full, final game.
For Digital Legacy or Digital Deluxe Edition owners, your game will be automatically updated to the full version no later than November 4th, exact times will vary by region.
