Here’s everything arriving in season three of MW3 when it comes to multiplayer. Check out our list of patch notes for Warzone and MW3 Zombies for more info on those modes.

Weapon balancing and bug fixes

As is always the case, MW3’s new seasonal update adds a bunch of weapon changes and fixes to bugs and issues plaguing the game. But there’s also some fun new additions to stuff like the UI design.

As far as weapon changes, some big nerfs are in store for the RAM-7, Holger 556, and MCW, which have been dominant assault rifles since they released. Sledgehammer says that “with the MCW, one headshot will no longer result in a four-shot kill.”

Interestingly, incendiary damage has received a 33 percent increase for the Thermite grenade, so don’t be surprised to see more of them in the game. Other tacticals and lethals have also been tweaked.

Additionally, all MW2 weapons have received a significant buff with improvements to clarity while firing, and global changes to ADS Idle Sway which is “now a predictable motion, raising the skill ceiling by eliminating randomness and encouraging weapon mastery,” according to Sledgehammer.

Overall, there have been many changes to multiple meta guns and weapon archetypes in general. For the full list of changes, check out the patch notes on CoD’s website.
