This guide lists out all the Dark Ops Challenges with an explanation of what you need to do for each one. We also have an in-depth strategy guide that shows you the exact tactics you should employ to complete each challenge here.
NOTE END
Among the many challenges in Black Ops Cold War are 'Dark Ops' challenges, which are meant to be unknown to players until they have completed them. Dark Ops challenges are a set of tasks that players must complete to earn the associated rewards.
The idea of them being "dark ops" is that you don't know what the specific challenges are until you have inadvertently carried them out while playing through the game organically. Dark Ops was last seen in Black Ops 3 and they now make their return in Black Ops Cold War. Dark Ops challenges are available for campaign, multiplayer, and zombies modes.
Although the Dark Ops challenges are meant to be unknown events that you unknowingly complete, the full list of all challenges has been leaked. Below, we have listed all the Dark Ops challenges across all three game modes, as well as the completion requirement and associated rewards when you meet those requirements.
