Call of Duty: Modern Warfare 3 and Warzone's Season 4 Reloaded update delivers a massive content drop, including new game modes, weapons, and significant changes to the existing meta. The update has been highly anticipated, especially the addition of new Zombies content to Modern Warfare 3.

Recent weeks have been exciting for Call of Duty fans. Following the Season 4 update earlier this month, the next installment in the franchise, Call of Duty: Black Ops 6, was fully unveiled at the Xbox Games Showcase. While fans await its release, Sledgehammer Games and Infinity Ward are introducing substantial updates to Modern Warfare 3 and Warzone.

Activision's patch notes detail the additions: two new weapons—the Reclaimer 18 shotgun and the Sledgehammer melee weapon—along with JAK Volkh and JAK Gunslinger aftermarket parts. A new Mutation mode removes tactical and lethal equipment from ground loot, requiring players to collect DNA for perks. Modern Warfare 3 Zombies gains the Unstable Rifts feature, a wave-based combat challenge rewarding cooldown resets on insured weapons and schematics.

This update significantly alters the game's meta. The Kar98k, a recent addition that surpassed the popular MORS sniper, has received nerfs to its damage range and bullet velocity. Controller aim assist has also been adjusted.

Conversely, several previously dominant weapons have been buffed, offering players a chance to revisit their favorites. The FJX Horus, Striker, and Rival-9 SMGs, alongside the MTZ 762, MCW, Holger 556, and MTZ 556 rifles, all received improvements. The interplay of these buffs, nerfs, and new weapons promises dynamic gameplay changes.
