Call of Duty: Modern Warfare 3 and Warzone's Season 4 Reloaded update delivers a massive content drop, including new game modes, weapons, and a highly anticipated Zombies feature. The update follows the recent Season 4 launch and the unveiling of Call of Duty: Black Ops 6 at the Xbox Games Showcase.

This Reloaded update introduces significant changes, as detailed in Activision's patch notes. Two new weapons—the Reclaimer 18 shotgun and the Sledgehammer melee weapon—join the arsenal, alongside JAK Volkh and JAK Gunslinger aftermarket parts. A new Mutation mode shakes things up by removing tactical and lethal equipment from ground loot, requiring players to collect DNA for perks. Modern Warfare 3 Zombies gets the Unstable Rifts feature, a wave-based challenge rewarding cooldown resets for insured weapons and schematics.

The meta will shift dramatically with weapon adjustments. The Kar98k, previously a top sniper rifle, receives nerfs to its damage range and bullet velocity, while controller aim assist has also been tweaked. Conversely, several previously popular weapons, including the FJX Horus, Striker, and Rival-9 SMGs, and the MTZ 762, MCW, Holger 556, and MTZ 556 rifles, receive buffs.

Here's a summary of the key additions and changes from the official patch notes:
