Sledgehammer are trying to win over the hearts of CoD players, and so they've undone all the most unpopular changes made by IW last year. But if they want to keep the goodwill of the community for very long, they will need to keep making great decisions for MW3 throughout its lifecycle. And that starts with regular, intelligent balancing changes.

In this article we have the full patch notes, the patch size and a short guide on when you can expect future patches. Let's dig in and see if the latest buff and nerfs in MW3 make any sense!


Modern Warfare III Season 3 Update (April 3) | Patch Size

This patch is at least 20 GB across all platforms. It's so big because it contains all of the Season 3 content, which is a lot (for both multiplayer and Warzone). We're talking new maps, new guns, dozens of new bundles, and quite a few bug fixes.

The game is obnoxiously big, but at least you can delete all of MWII now.

When Does Modern Warfare 3 Get Updated?

We expect Modern Warfare 3 to receive near daily updates during the beta, but when the full game launches, we predict it will be updated every Wednesday at 9 am PT (12 pm ET / 5 pm GMT / 6 pm CET). This is exactly when the last three Call of Duty games were updated each week, and we don't see why the devs would change their workflow. They will occasionally have weeks off when they don't push out an update, for instance on the week of Christmas.

How Can You Check For MW3 Patch Notes In-Game?

You can also check Patch Notes in-game, however this feature is often bugged. If you want to re-check the patch notes from in-game, and if the feature is working, just do the following:

  1. Press ESC/Start from the main menu, and a new menu will pop out on the right side of the screen. Tab across to the Settings section (represented by a cog symbol), you will find "Patch Notes" at the bottom.Modern Warfare 3 III Update Patch Notes - How To Check In Game 1
