One of the Easter Egg steps on Terminus requires you to “Input the Sequence,” but how do you do that?

The Terminus Easter Egg in Call of Duty: Black Ops 6 Zombies is currently the hardest one to complete. There’s a myriad of difficult steps and a particularly challenging boss fights that players have to work through.

However, before any of the truly difficult steps come to fruition, players have to do a little math homework. One of the early steps in the Terminus Easter Egg requires you to “Input the Sequence,” which isn’t clearly explained in Zombies.

The Input the Sequence step comes after you activate all three of the Harmonic Triangulators on the map. Both of these steps work together, but you’ll need to study your surroundings if you want to move on to the next step in the Easter Egg.

How to find the Harmonic Triangulators in Zombies

First off, you’ll need to find and activate three Harmonic Triangulators that are spread out across theTerminus map. The triangulators aren’t located too far apart from one another, so you won’t have to travel too far. Below, you can see a location description for each Harmonic Triangulator:

Once all three Harmonic Triangulators are activated, go back up to the prison area of Terminus to “Input the Sequence.”

How to Input the Sequence in Zombies

The “Input the Sequence” step needs to be done inside the small office room in the central courtyard. Inside, you’ll see a large machine on a desk that can be interacted with. When you go to interact with the machine, it will say “Input Sequence.”

From here, look at the three yellow post-it notes on the machine in front of you. The symbols right below the “X,Y,Z” letters are what you need to remember. Every player’s symbols are random, so you and another player likely won’t have the same ones appear. There’s a complicated math equation that’s required to solve the meaning behind the symbols, but you don’t need to do that. Instead, simply head toTerminussolver.com.

This site allows you to input your specific symbols for each letter. Simply look at the post-its, find the symbol that corresponds with each letter on the site, click the symbol, and then out will pop three numbers. You need to enter those numbers into the machine in the order you see them on the site.

If you did everything correctly, your numbers will turn green and Peck will come over the radio to congratulate you. This step of the Easter Egg on Terminus is now complete. For those of you that have moved on from this step but might be struggling with future boss fights, make sure you’re using one of ourtop five weapons in Zombies.
