Infinity Ward has share more details on the April 28 update for Call of Duty: Modern Warfare and Warzone, including the preliminary patch notes and the file size.

In a blog post, Infinity Ward clarified that the update is about 15 GB in size, and it will be available on PlayStation 4 and Xbox One. The update delivers the Data Pack 1, and it must be downloaded to keep playing the game. This appears to be a console-only update.

In addition to the Data Pack, the April 28 update will include a series of bug fixes and changes (across console and PC). One of the big ones is that the speed and size of the Warzone gas circle has been “adjusted,” but Infinity Ward did not provide any further details.

In terms of bug fixes, the April 28 update takes care of an issue that could cause players to lose the ability to select a favorite faction from the Operator menu. It also fixes a bug that could cause watches to appear in the wrong direction when using a gesture. There are also a variety of fixes for problems related to challenges and weapon unlocks, among other things.
