Modern Warfare and Warzone Update 1.34 Patch Notes

Update 1.34 has arrived for Call of Duty: Modern Warfare and Warzoneand here is the full list of changes and fixes added in this patch.

Much like many other Call of Duty updates, the file size is really huge today. The PS5 and PS4 versions of the game are 52 GB each! The Xbox Series X / S and Xbox One sizes are 57.8 GB. The PC version is only installed for Warzone 52.4 GB and for Modern Warfare and Warzone 133.6 GB.

According to Raven Software, the reason the file size is so large is “to optimize the data.” You may also want to invest in more hard drive space if the game takes up too much space! You can read the patch notes below.
