The Cointoss Helm is one of the most practical items you can pick up in Totenreich, and most players walk right past the mechanic that unlocks it. Hidden inside Tyr's Head, this Viking helmet dramatically improves your Power-Up drop rate, making high-round runs significantly more manageable in Call of Duty: Black Ops 7. Here's the full breakdown of how to get it and why you should bother.
How does the Tyr's Head coordinates easter egg work?
The Cointoss Helm is tied to a repeatable mini-easter egg inside Tyr's Head, which you can access from either Tyr's Shoulder or Tyr's Foot. Once inside, head to the central terminal. You'll see two pieces of information displayed: a letter-number combination (your location coordinates) and a second number (your kill target for that area).
Your job is simple: go to the location those coordinates point to, kill the required number of zombies there, then return to Tyr's Head to collect your reward. Green lights on Tyr's Head confirm you've hit the kill requirement before you make the trip back.
On Cursed mode you won't have access to the Tac Map, so memorize the coordinate grid below before you start. It saves a lot of backtracking.

The following coordinates map to these Totenreich locations:
Each time you complete a set of coordinates, you can return to Tyr's Head on the next round to receive a free Power-Up and a fresh set of coordinates. The easter egg resets per round, so you're building toward the helmet over multiple runs through the cycle.

How do you unlock the Cointoss Helm?
You need to complete the Tyr's Head coordinates easter egg a total of 10 times. That means 10 separate coordinate missions, each confirmed with green lights on Tyr's Head, each rewarded with a Power-Up pickup. After the 10th completion, return to Tyr's Head and instead of a Power-Up, you'll find the Cointoss Helm sitting on the floor waiting to be picked up.
What does the Cointoss Helm actually do?
The name tells you exactly what to expect. The Cointoss Helm acts as roughly a 50/50 chance of triggering a Power-Up drop on your next zombie kill. That's a meaningful boost over the base drop rate, and the effect is noticeable in practice.
Power-Ups that show up more frequently with the helm equipped include:
- Insta-Kill (the most valuable for high rounds)
- Double Points
- Firesale
- Max Ammo
- Nuke
Insta-Kill is the real reason to chase this helmet. At high rounds, zombies become damage sponges, and a well-timed Insta-Kill can clear an entire horde in seconds. The more consistently you can trigger those drops, the faster your rounds move.
The Cointoss Helm is a wearable item, meaning it occupies your helmet slot. Factor that into your loadout planning before you commit to the 10-round grind.

Is the Cointoss Helm worth the grind?
For high-round play, yes. The 10-completion requirement sounds steep, but each run through the coordinates also rewards you with a free Power-Up, so you're not grinding for nothing. You're getting real in-round value the entire time you're working toward the helmet.
For players just trying to complete the main easter egg or hit moderate rounds, the helmet is a nice bonus rather than a necessity. The coordinate system is worth doing regardless because of those free Power-Up drops.
The Cointoss Helm is one of three Viking Helmets available in Totenreich. If you're collecting all of them or want to see what the map's other hidden mechanics have to offer, check out the full Totenreich Relics guide for a broader look at the unlockable items on the map.
