For Call of Duty Modern Warfare and Warzone , a large update download is scheduled for the start of Season 4 on June 10th in the morning. Activision Blizzard is already warning: The download will be large. Sources report up to 49.7 gigabytes on PC, nearly 49 GB on Xbox One, and 34.7 GB on PS4. Why is the patch so large? To save hard drive space.
Update June 11, 6:00 AM: It’s actually happening today, the patch notes for the large Season 4 update have just been released: CoD MW & Warzone: New update and Season 4 are coming today – What’s changing
When is the patch coming? The patch is scheduled to arrive at 8:00 AM on Thursday, June 11th, German time, which introduces Season 4 for Call of Duty: Modern Warfare and Call of Duty: Warzone.
The download is supposedly this large: A leak that also correctly predicted the release date of Season 4 mentions the following sizes: (via twitter):
- 34.7 GB – PlayStation 4
- 48.9 GB – Xbox One
- 44.3 GB – PC (for players who are only playing Call of Duty: Warzone for free)
- 49.7 gigabytes – PC (for players enjoying the full Call of Duty program, i.e., premium players)
The patch will be large, but hard drive space will be saved
Is this confirmed? Sort of, the exact GB data has not yet been confirmed. However, community manager Ashton Williams warns: The Season 4 download will indeed be large.
Based on the statement from the community manager, the gigabyte numbers from the leak sound plausible. If the community manager says that the download will be “large,” then it will likely be very large.
Why is the patch so large? However, the “hard drive storage consumption” of Call of Duty Modern Warfare and Warzone should not increase as much as the large patch suggests.
It is said that a number of assets are being compressed, so the launch of Season 4 will only consume 4 gigabytes more space on the hard drive than the version without Season 4 does now.
The hard drive size of Call of Duty is becoming a problem, especially on PS4 and Xbox One. Players there barely have space for additional games alongside Call of Duty. Here we have revealed how you can reduce the hard drive consumption of CoD on PS4 and Xbox One.

Players of Call of Duty have been waiting for over a week for Season 4 to finally start. There is not much known yet about the new chapter, but what we know about the new season in Modern Warfare and Warzone is revealed in our article on the start of Season 4.
