Call of Duty: Modern Warfare 3 and Warzone's Season 4 Reloaded update dropped today, packing in new game modes, weapons, and a wealth of additional content. The update, eagerly anticipated by fans, especially features the highly-requested Zombie content for Modern Warfare 3.

Recent weeks have been busy for Call of Duty enthusiasts. 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 have unleashed substantial changes to Modern Warfare 3 and Warzone.

Activision's blog post detailed the Season 4 Reloaded patch notes. Two new weapons—the Reclaimer 18 shotgun and the Sledgehammer melee weapon—are introduced, alongside JAK Volkh and JAK Gunslinger aftermarket parts. A new Mutation mode removes all 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 patch significantly alters the Modern Warfare 3 and Warzone meta. The recently added Kar98k, previously outperforming 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. Popular Warzone SMGs like the FJX Horus, Striker, and Rival-9 see improvements, along with the MTZ 762, MCW, Holger 556, and MTZ 556 rifles. The introduction of new weapons adds further intrigue to the evolving gameplay dynamics.
