Call of Duty: MW3 Season 4 Reloaded Update Goes Live With Extensive Patch Notes (2024)

Season 4 Reloaded brings a ton of new content to Modern Warfare 3.

By Logan Moore

Call of Duty: Modern Warfare III's massive Season 4 Reloaded update has now gone live across PlayStation, Xbox, and PC. With Season 4 now halfway over, Activision has pushed out its standard Reloaded patch as a way of giving MW3 more content until the start of Season 5. To that end, this new update contains massive overhauls of the meta of MW3 while also incorporating new modes, maps, and other alterations to Zombies.

When it comes to the new additions for Call of Duty: Modern Warfare III, three new 6v6 maps titled Incline, Das Gross, and Bitvela have been brought to the game. These maps join five new game modes, two new weapons, and a litany of balance changes for the guns already found in MW3. On the Zombies side of things, a new challenge called Unstable Rifts has been added. This mode is wave-based and will have players fighting off hordes of zombies after entering "rifts". All of this new content is joined by a ton of bug fixes that have been made to all aspects ofMW3.

To get a look at everything that is included with this Season 4 Reloaded update for Call of Duty: MW3, you can find the full patch notes attached below.

We'll continue to monitor feedback for further opportunities to increase the variety of Weapon usage in the competitive experience.



Get ready for a new wave-based combat challenge: Unstable Rifts. When you enter an Unstable Rift, you'll face increasingly intense waves of enemies. Win and the cooldown will reset on all your insured weapons and schematics, letting you enter the next match fully equipped. If you miss the chance to join a Rift, Strike Team Operators can locate additional opportunities on the map.

Beware, Unstable Rifts are unpredictable. Some things work differently; some advantages are given, and others taken away. However, the loot is worth it: a maxed-out Pack-A-Punch weapon with maximum Rarity to use while in the Rift, plus free Perks and Upgrades to help you face the hordes.
