Weapon Unlock Challenges Now Available in Zombies for Black Ops Cold War

Here's how to unlock the Season One and Season Two weapons in Call of Duty: Black Ops Cold War Zombies.

With the launch of Season Three of Call of Duty: Black Ops Cold War and Warzone, Treyarch has given players the opportunity to unlock all-new weapons through the Zombies experience. Previously, those who desired new weapons would be required to purchase a Bundle or complete the unlock challenges in Multiplayer or Warzone. Now, players can drop into the traditional round-based Zombies mode or the large-scale Outbreak mode to earn the latest content.

Going forward, we will provide the unlock challenges for the latest weapons in their designated articles; however, for the previously-released weapons from Season One and Season Two, you can find their corresponding requirements below.
