Modern Warfare 3 launch patch notes detail campaign fixes and multiplayer updates


Sledgehammer Games has released the launch day patch notes for Call of Duty: Modern Warfare 3.

Republished in full below, they primarily cover various changes made to the game’s multiplayer component since last month’s beta tests.

The update also fixes a number of campaign gameplay bugs, stability and performance issues.

Modern Warfare 3 was officially released today for PS4, PS5, Xbox One, Xbox Series X/S and PC.

The game is a direct sequel to last year’s Modern Warfare 2. Development is being led by Sledgehammer, in collaboration with Infinity Ward, while Treyarch is in charge of its Zombies mode.

According to a new report, Modern Warfare 3 and some of its creators suffered from a rushed development cycle that saw its campaign made in about 16 months.

Over a dozen developers told Bloomberg that the project started life as an expansion to last year’s Modern Warfare 2 before Activision decided to transform it into a full-blown sequel, claims which the publisher has denied.

“Sold as a pre-order bonus and given about as much thought, Call of Duty Modern Warfare 3’s single player offering is a short, shallow waste of time that feels less like a video game and more like a contractual obligation,” according to VGC’s review.

Alongside the release of the game’s first patch notes, Sledgehammer said: “Today’s launch is only the beginning, and we look forward to providing a consistent stream of content updates, bug fixes, and gameplay adjustments in the year ahead.”
