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 3 Season 2: Reloaded Update (March 6) | Patch Size

This patch is about 19 GB across all platforms because it contains a lot of new content for Season 2: Reloaded. Remember, we're getting new map variants of Skidrow and Terminal, a remaster of Vanguard's Das Haus, and a lot of new skins. It also introduces some 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:
