You'll need your Infinite Warfare disk to play the Modern Warfare download – and how to play campaign mode tomorrow

***UPDATE: We've clarified how to play Modern Warfare Remastered's Campaign mode on PS4 on October 5th, plus the conditions in which you'll need an Infinite Warfare disc inserted in order to play Modern Warfare.***

After the fuss yesterday about the Infinite Warfare disk being required to play Modern Warfare Remastered, Activision have clarified the issue in a new FAQ.

Modern Warfare Remastered requires a download, but accessing the game depends on which console you're using. PS4 players will use a voucher code contained in the Infinite Warfare box which you'll have to input in the Playstation Store in order to download Modern Warfare. Xbox One players will find Modern Warfare included on the Infinite Warfare disk but you need an internet connection to activate the game.

So, do you need a disc inserted to play Modern Warfare Remastered? Yes – but there is an exception, which we'll explain in the paragraph below. For most PS4 and Xbox One owners, you'll need the Call of Duty: Infinite Warfare disc in your machine to play Modern Warfare Remastered's multiplayer and campaign modes, when Infinite Warfare launches on the 4th of November. Steam users have it easy and will be given a single key that accesses both games.

So, how can I play Modern Warfare Remastered's campaign tomorrow i.e. 5th October?

If you want to play Modern Warfare Remastered's campaign mode before the launch of Call of Duty: Infinite Warfare on 4th November, you'll need to pre-order either the Digital Deluxe Edition or the Legacy Edition on PS4 via the PlayStation Store, which you can do anytime before Infinite Warfare's launch – and Modern Warfare Remastered's campaign mode goes live as a PS4-exclusive from 5th October. Phew.

Here are the full details:

PlayStation 4
Call of Duty: Modern Warfare Remastered is a full game digital download that will be included in the Infinite Warfare Legacy Edition and Legacy Pro Edition on PlayStation 4. The digital download is redeemed via a voucher code on an insert in the box. The Infinite Warfare game disc must be inserted to play Modern Warfare Remastered. Internet connection is required.

Xbox One
Call of Duty: Modern Warfare Remastered is included on the Infinite Warfare Xbox One disc (no voucher code required) in the Legacy Edition and Legacy Pro Edition of Infinite Warfare. Before Modern Warfare Remastered can be played, an additional download is required. The game disc must be inserted to play Modern Warfare Remastered. Internet connection is required.

Steam
A Steam key will be provided in the Legacy Edition of Infinite Warfare that will provide access to both Infinite Warfare and Modern Warfare Remastered. Internet connection is required.

Presumably the Infinite Warfare disc has to be inserted to play the game to stop nefarious individuals from downloading Modern Warfare Remastered and then selling on the Infinite Warfare disk as quickly as possible. (Admit it, you're thinking about it.)

The small print goes on to say that an internet connection is required, though it doesn’t specify whether this is needed just to download Modern Warfare Remastered or if you need to remain online to play.
