The arrival of Totenreich to Black Ops 7 Zombies brings a host of new challenges for us, and having the Jotunn Star will make things slightly easier to manage. It’s a brand new Wonder Weapon that can be found on the map itself, and it’s perfect to effortlessly clear waves of undead.
So first, let’s find out how you can obtain it.
How to get the Jotunn Star in Black Ops 7 Zombies
The key to obtaining the new Wonder Weapon is locked behind the shrine at Burial Grounds. However, the door to the shrine will be locked. To unlock the door, you’ll need the Chain Links quest item. This is a necessary step, and you can find the Chain Links on the front tip of the big boat (refer to the image below) at Dry Dock.

How do you get the Chain Links? For starters, I didn’t find a way to get on the boat, which would have made things comfortable. However, you’ll find a pair of buttons in a room to the left of the stationary boat. Press the button, and it will activate a nearby crane that moves down a container.
You have to quickly jump on the container and do a second jump (wall jump, to be precise) to the tip of the boat. While you’ll likely fall, you’ll have obtained the Chain Links.
You’ll also need two other items apart from the Chain Links.

- Lantern: You’ll need to survive until wave 10, when you’ll encounter a special round. Defeat all the enemies and survive Wave 10, and you’ll find the Lantern as a guaranteed drop.
- Chili Chunks: You can find the item behind a truck located just beside the Deadshot Daiquiri machine on Storm Bridge.

Once you’ve all three items, head to the basement of the room in Burial Grounds that you opened with Chain Links. Place the Lantern on the tomb in the middle, and it will trigger a lockdown. Clear all the zombies first; then, interact with the constellation symbols on the walls. Using the opening door of the shrine as the reference, the correct order is Left, Right, Back, and Front.

If you manage to complete this step correctly, the ghost of Astrid will appear. Your next task is to follow the spectre all the way to the Lighthouse. If it stops, you’ll need to kill zombies near it to feed their souls. Once replenished, the ghost of Astrid will start to move automatically.
Take the zipline and go to the Lighthouse. Once the ghost of Astrid arrives over there, it will create platforms for you to climb on. Use the platforms to reach the Lighthouse, and enter from a broken entrance on one side.

Head inside, and use the stairs to climb up. You’ll need to use the platforms and the stairs to reach all the way to the top. The Jotunn Star will wait for you at the top, and you can upgrade the Wonder Weapon using a Pack-A-Punch.
