Modern Warfare 4 Season 1 Weapons Guide [Full Unlock]

Modern Warfare 4 Season 1 officially launched in November 2026, introducing four brand-new tactical weapons that significantly expand the core competitive multiplayer arsenal across diverse combat categories, according to verified reports from Sportskeeda Esports & BGMI. The major seasonal update brings two immediate launch weapons—the Cronen Osprey assault rifle and the CSG-35 submachine gun—alongside two in-season additions, the JAK 12 shotgun and ZLR Talonhawk melee combat axe. The standout Cronen Osprey utilizes standard 5.56mm ammunition and boasts a blazing 882 RPM fire rate mirroring the fan-favorite M4 platform. Players can instantly unlock the Cronen Osprey by reaching Tier 16 on the Season 1 Battle Pass, while a specialized weapon blueprint becomes available at Tier 87. Meanwhile, the CSG-35 redefines close-quarters combat dynamics, offering exceptional mobility and rapid target acquisition for aggressive entry fraggers. As players grind through early-season qualification matches and weapon mastery challenges, esports organizations are actively evaluating how these lethal firearm additions impact weapon balance, recoil management, and professional meta strategies across upcoming tournament circuits.
