The latest patch update for Call of Duty: Modern Warfare deployed on February 11 to start Season 2 of the game, and the file size for the update has surprised everyone. The update is 51GB on PS4, 68GB on Xbox One, and 67GB on PC.
Infinity Ward Producer on Twitter has explained why the file size is this large in a series of tweets. “I just want to apologize about the download size of this update.”
He says this is what caused the update so big.
this is what has caused the update today to be so big. after todays download you should see that, even though we've added season 2 and the associated content for it, the overall size of the game should shrink a little on your local hard drive.— Paul Haile (@Tyrael) February 11, 2020
He has also confirmed that they are working towards a better management system for the files going forward and reducing file size.
in addition to this update keeping the disk footprint from increasing, we're also taking this opportunity to set up the data up for better overall management to try and keep future updates from being this large, even during a season rollout.— Paul Haile (@Tyrael) February 11, 2020
They said they are aware of it and woking towards reducing the size.
