All weapon buffs and nerfs in MW3 and Warzone Season 4

Modern Warfare 3 and Warzone Season 4 are finally here and there are some pretty big weapon changes that are sure to shake up the meta.

Every time a new seasonal update for Modern Warfare 3 and Warzone arrives, fans don't hesitate to check what new changes are coming. This time around, the battle royale sees the number of players increase to 120 and the multiplayer gets a few new maps.

On top of that, these new updates also bring new weapons, as well as changes to the current weapon arsenal. These updates also change the meta in Warzone and normal multiplayer.

It will be the same story in Season 4, as the developers finally tackled the BP50, DG-58 LSW, and Striker 9 with some changes. So here's what you need to know about the new set of weapon changes.

All Warzone and Modern Warfare 3 weapon changes in Season 4

As for the big changes, the previously mentioned meta options in BP50, Striker 9, and DG-58 LSW have all been changed. The BP50 has had its movement speed decreased across the board, while the Striker 9 has had its damage ranges and headshot multiplier nerfed.

Additionally, the SVA 545 was also nerfed as the developers looked to change the assault rifle's average damage range and reduce the headshot multiplier.

On the other hand, the BAL-27, MCW and FJX Horus have also seen some interesting upgrades. Horus has undergone some of the biggest changes in the group and should be pushed into the meta moving forward.

As always, some of these changes will only apply in multiplayer, while others are specific to Warzone. This is evidenced by the radical changes made to SMGs. So be aware of this when making changes to your uploads.

The full list of buffs and nerfs from Season 4 weapon changes can be found below.
