All weapon buffs & nerfs in Warzone & Black Ops 7 Season 1

Warzone and Black Ops 7 finally integrate in Season 1, bringing a host of changes set to shake up the multiplayer and battle royale meta.

Described as “the biggest Season 01 ever,” the December 4 update brings new weapons, Operators, maps, and modes to multiplayer, and the new Astra Malorum map in Zombies.

Over on Warzone, not only do all of Black Ops 7’s weapons arrive in the battle royale, but the update brings the new Haven’s Hollow Resurgence map, reduced skill-based matchmaking, aim assist nerfs, and more.

But an update wouldn’t be complete without a meta shake-up, so here are all of the weapon buffs and nerfs in Warzone and Black Ops 7 Season 1.
