If you install both Call of Duty: Infinite Warfare plus Modern Warfare Remastered, you need at least 130GB of space free on your hard-drive.
That's according to the back of the PlayStation 4 version of the Call of Duty: Infinite Warfare Legacy Edition, which itself was revealed by a French retailer (thanks, Charlie Intel).
Now, it comes as no surprise to learn that the two games' combined installation size is larger than a single Call of Duty, but 130GB total is something of an eyebrow-raiser. That's over a quarter of your 500GB console hard-drive.
We don't know the exact breakdown because Activision has yet to confirm it, but we can suggest that 40GB is for Modern Warfare Remastered, as that's the size of the MWR Campaign Early Access currently available to download on PS4.
That leaves a whopping 90GB for Infinite Warfare. Perhaps the size is the result of support for the 4K-fuelled PlayStation 4 Pro? We've asked Activision for clarification.
Meanwhile, it's worth noting that if you have downloaded the 40GB Modern Warfare Remastered Campaign Early Access to your PS4, come launch day, you'll have to download the game again.
Per the FAQ on Activision's website:
The early access period will end on November 3rd. On launch day, you must install the full version of Modern Warfare Remastered that is included with the Call of Duty: Infinite Warfare Legacy Edition, Legacy Pro Edition, Digital Legacy Edition or Digital Deluxe Edition.
So, let's say you're downloading the whole lot - that is, Modern Warfare Remastered Campaign Early Access, then Infinite Warfare and Modern Warfare Remastered on 3rd November. You've got 40GB now, then potentially 130GB on launch day. Ouch.
Oh, and let's not forget, if you go physical, you need to have the Infinite Warfare disc inserted in your console to play Modern Warfare Remastered.
