The season one update for Call of Duty: Black Ops Cold War will soon be live and Treyarch has posted the patch notes to go along with it.

In the update, there’s weapon tuning for multiple classes, including tactical rifles. There’s also perk tuning for perks like Flak Jacket, updates to multiplayer modes, spawn improvements, Zombies fixes, and PC stability updates.

The update size varies depending on the platform, but it ranges from 3.4 GB to 7.1 GB. This is obviously a huge change of pace from Modern Warfare’s gargantuan updates, which routinely came in at 50 GB or more.

Season one of Black Ops Cold War also adds two new weapons, the MAC-10 and Groza, a new Operator, a bunch of new maps including Raid from Black Ops 2, and 100 tiers in the new battle pass.

Here’s the full list of patch notes for season one, which goes live on Dec. 16 at 1am CT:
