1. ⚡ Turn on the power

Tag has two power switches.

The first is near the Docks/Boathouse side of the map.

The second is at the Lighthouse.

Turn on both so you can access the map’s major systems.

While you’re opening everything, start getting your normal setup together.


2. 🔫 Unlock Pack-a-Punch

Tag’s Pack-a-Punch system revolves around the Lighthouse.

After power is restored, locate the Blue Rock associated with the Hermit at the top of the Lighthouse and complete the initial interaction.

The Hermit eventually provides access to Pack-a-Punch.

You’ll notice PaP can appear at different locations around the map.


3. 🛡️ Build the shield

Collect the three shield pieces scattered around the facility.

Take them to a workbench and construct the:

🛡️ RIOT SHIELD

Keep it repaired. Tag gets pretty nasty later.


4. ❄️ Get the Wunderwaffe DG-Scharfschütze

Tag brings back the Wunderwaffe, except this version is a freaking sniper rifle. 😂

You can obtain the Wunderwaffe DG-Scharfschütze through its side quest.

It’s extremely useful for dealing with groups of zombies and worth having before the later stages.


5. 🧊 Obtain the elemental shard

Now we start working toward the main quest.

You’ll need to complete the required interactions around the map involving the Lighthouse/Hermit and eventually obtain:

💎 ELEMENTAL SHARD

This becomes one of the central ingredients for building the Agarthan Device.


6. 🔥 Get the Heat Pack

You’ll also want the:

🎒 HEAT PACK

Complete the challenge involving the map’s launch pads/zipline system and bring the required components to the Hermit.

The Heat Pack lets you survive in areas where the freezing water would normally become a major problem.

You’ll definitely appreciate this later.


7. ☀️ Golden Pack-a-Punch

Tag has one of the coolest PaP side mechanics in BO4.

Eventually you can access the remote island containing:

🌟 GOLDEN PACK-A-PUNCH

Using it allows you to fully upgrade a weapon in one go.

Not absolutely mandatory for every step, but if we’re ending the Aether storyline, we might as well show up armed properly. 😂


8. 🪨 Find the THREE offerings

The main quest requires several special components.

Search around Tag for the required offerings/items associated with the Hermit and Lighthouse ritual.

Bring them to their corresponding locations.

These eventually allow you to begin assembling the:

🔮 AGARTHAN DEVICE


9. 🔮 Build the Agarthan Device

The Agarthan Device requires several major components, including the:

💎 Elemental Shard

and the quest’s other ritual components.

Once everything has been collected, assemble them.

You now possess:

🌌 THE AGARTHAN DEVICE

And Nikolai’s plan is officially underway.


10. 🗿 Seal of Duality

You’ll obtain the:

🌓 SEAL OF DUALITY

The Seal must be placed at specific locations around Tag der Toten.

At each location:

Place Seal → kill zombies → charge it → survive → retrieve Seal.

You’ll repeat this at multiple locations.

As the quest progresses, things become increasingly chaotic.


11. 🧟 Complete the Seal challenges

Every Seal location creates a lockdown-style encounter.

Stay near the Seal and feed it zombie souls.

You’ll face increasingly difficult enemies.

Don’t wander too far away or you’ll make the process harder.

Once a Seal is completely charged:

PICK IT BACK UP.

Move to the next required location.

Repeat.


12. 🏮 Lighthouse challenge

Eventually you’ll bring the quest back toward the Lighthouse.

The Lighthouse beam becomes involved with the Agarthan Device.

Follow the Hermit’s instructions and complete the required interactions.

The Lighthouse begins projecting energy around the map.


13. 🎵 Samantha’s Music Box

You’ll eventually obtain:

🎶 SAMANTHA’S MUSIC BOX

Yes—Samantha has apparently decided that the finale of the Aether storyline needs a tiny music box capable of absolutely wrecking zombies. 😂

Save it for difficult lockdowns.

It’s extremely powerful.


14. 🔮 Charge the Agarthan Device

Take the Agarthan Device through the required ritual locations.

You’ll need to fill it with energy.

Kill zombies nearby.

Their souls enter the Device.

Continue until it becomes fully charged.


15. 🌊 Take the Device through Tag

Now comes the long final sequence.

You’ll need to escort/carry the charged Device across the map.

The environment becomes increasingly dangerous.

Stay together in co-op.

On Solo:

KEEP MOVING.

You’re going to be dealing with large numbers of enemies while following the Device’s route.


16. ❄️ THE FINAL ESCORT

The Device begins traveling toward the final destination.

Follow it.

You’ll encounter repeated lockdowns along the way.

At each stop:

Protect yourself → kill enemies → charge/progress Device → continue moving.

This is essentially Tag’s replacement for a traditional giant boss fight.


17. 🏔️ Reach the facility

Continue following the Device through the map.

Eventually you’ll reach the final area.

The screen begins changing as the Agarthan Device reaches full power.

Complete the last interaction.

And then…

🎬 THE FINAL CUTSCENE

This isn’t just the ending of Tag der Toten.

It’s the ending of the storyline we’d been following since the earliest Treyarch Zombies maps.

Victis successfully delivers the Agarthan Device.

But Nikolai reveals that his real plan isn’t to win another war.

It’s to end the cycle entirely.

Primis and Ultimis celebrate together around a campfire.

Then Nikolai carries out the final part of his plan.

Samantha is left with the final responsibility.

She destroys Nikolai.

The multiverse collapses.

The corrupted realities, the Apothicons, Monty, the Keepers, Element 115 and everything tied to the cycle are sent into the Dark Aether.

And Samantha and Eddie walk toward a new universe.
