The Modern Warfare 2 and Warzone 2 Season 1 update added a long laundry list of weapon balancing. Here’s a breakdown of every nerf and buff included.

After just under a month of leaving up and testing every gun in Modern Warfare 2, the game’s meta is beginning to slowly take shape.

The Kastov-74u, M4, and SP-R 208 emerged as early front runners for best weapon, but the jury is still out. We took a crack at ranking MW2’s best weapons and provided a loadout for each gun. The meta will continue to evolve, especially as players discover what weapons work best in Warzone 2.

Modern Warfare 2 Season 1 update made wide-sweeping changes to weapon balancing.

Most significant weapon buffs and nerfs

One of the most significant changes made is an increase in long-distance flinch on all Assault Rifles SMGs, and LMGs.

The Kastov-74u, M4, STB 556, and SP-R 208 all received much-needed nerfs but nothing that will completely take them out of the game’s meta.

Players should have less to fear when going up against a Kastov-74u or STB 556 in close-quarters combat.

While the FSS Hurricane, PDSW 528, and M16 received buffs to help bring them in line with other offerings. The M16 got a massive overhaul to its rate of fire, ADS movement speed, strafing speed, and recoil reduction.
