I spent more time watching YouTube videos trying to figure out the maps than I did running around the game itself.īut in Black Ops Cold War, Treyarch has brought the focus all the way back to zombies and how you kill them. 2018’s Black Ops 4 was so complicated that the features distracted from the fun. But in the 12 years since it was first released, Treyarch has added way too much to the mode. The wave-based survival mode is equal parts silly, challenging, and endlessly repeatable. The secret heart of Treyarch’s Call of Duty games since 2008 has always been Zombies.
