Black Ops 7 Zombies: How to Unlock Klaus on Ashes of the Damned

November 26, 2025 by Matt Villei

A familiar faceplate.

Back in Mauer Der Toten in Black Ops Cold War, our murderous best robo-buddy Klaus sacrificed himself to stop the Dark Aether incursion under Berlin. Now, he makes a return on Ashes of the Damned in Black Ops 7 Zombies. Held within an old western jail cell, players will need to complete a short quest to free our old friend and have him help the crew on their adventure. This quest involves taking down a tough enemy from Black Ops 6 and manually rebooting our synthetic companion. This guide will show players how to unlock Klaus on Ashes of the Damned in Black Ops 7 Zombies.


How to Unlock Klaus on Ashes of the Damned

To unlock Klaus, you will need to free him from the cell in the Sheriff’s Office. To get Klaus out of his prison, you will first need to progress through the game until you reach at least Round 8, which is when it’s possible to get an Uber Klaus Elite Enemy to spawn. You will need to defeat this enemy to start the quest of freeing the much smaller but friendlier Klaus. Before starting this fight, you will want to make sure you have some good weapons. I suggest having a weapon that is at least at the blue Rare rarity and Pack-a-Punch Level 1. This will give you a fighting chance, and if you can get above this level, the fight will be made even easier.

When you’re ready for the fight and are at Round 8 or beyond, go to Janus Tower Plaza. Go to the western part of the area and look up at the cliff made of destroyed road with a Project Janus crate on it. When you get close to it, Uber Klaus will burst out from the container. Target the shield generators on the mini-boss’s shoulders and then break its armor by targeting its arms and head. When you do enough damage to the large body, a Klaus core will eject. Take out this smaller robot to fully defeat the Uber Klaus. The enemy will drop a Stabilizer Chip that you will need to use to free Klaus.

The Sheriff’s Office is found in the northeast corner of Ashwood, to the left of the Vulture Aid Perk Machine. Once inside, you will find the cell with Klaus inside. Next to the cell door is a chip reader. Interact with it to insert the Stabilizer Chip. The system will start to activate, but will then say “Update Requires Restart.”

You will need to throw 2 Stun Grenades at Klaus to reboot his systems. You will know that you have successfully activated the robot if you see a stun icon above its head.

Klaus will stand up from the chair and fly out of the cell, landing in the map’s play area. You will be able to direct Klaus on where to go by using your Tactical button. He uses a Pack-a-Punched Assault Rifle and does a lot of damage, being able to sometimes throw LT53 Kazimir grenades. He will be active for a few minutes before returning to his cell. You can summon him again by spending 2,000 Essence at any of the Klaus consoles found in each area of the map.

You now know how to unlock Klaus in Ashes of the Damned in Black Ops 7 Zombies. Stay tuned to Gameranx for more news, updates, and guides for Black Ops 7 as well as other great games in the future.
