Treyarch has just released its latest patch notes on Reddit, and it is an astronomical list. The update touches things in every one of the game’s modes. Multiplayer gets a ton of balance updates and the Gun Game playlist, spawns have been tweaked, and Specialists get a few changes. Zombies sees some bug fixes. And Blackout finally gets the last of the Specialist character missions unlocked for players to pursue, among a number of other updates to the game’s Battle Royale mode. Let?s not waste any time and get right down to the list. I encourage you to make sure you?re in your comfiest chair.
