Shangri-La — Full Easter Egg

Setup

Turn on both power switches underground. You’ll eventually need the 31-79 JGb215 (Baby Gun) and later its Pack-a-Punched version, the Fractalizer. You’ll also need Spikemores and an explosive for specific puzzle interactions.

1. 🌑 Enter Eclipse Mode

At spawn, there are four buttons near Quick Revive.

Have all four players press their button at the same time.

The sky darkens and you’ve traveled into the past. You’ll need to reactivate these buttons whenever a later step requires another eclipse.

2. 🗿 Match the floor symbols

During the eclipse, activate the button near the MPL side.

Two sets of 12 pressure tiles appear on opposite sides of the map.

Two players should work together:

Player 1: Step on a tile and identify its symbol.

Player 2: Search the other set for the matching symbol.

Once you’ve found a matching pair, stand on both simultaneously. They’ll disappear.

Repeat until all 12 pairs are gone.

⚠️ Stepping on an incorrect pair can reset your progress.

3. 💦 Waterslide

Start another eclipse.

Have three players stand on the pressure plate at the bottom of the waterslide.

The fourth player goes down the slide. When they arrive, their added weight completes the pressure-plate puzzle.

You’ll return to the present when successful.

4. 💎 Crystal + Baby Gun

You’ll now need the 31-79 JGb215.

Start another eclipse and go toward the top of the waterslide. A large crystal/meteor will be above the slide entrance.

Knock it down, then use the 31-79 JGb215 to shrink it.

Melee the little crystal so it travels down the waterslide. Follow it and use the geyser/water spout to launch it into position.

Successful = another part of the mechanism activates.

5. 🔥 Napalm Zombie + gas

Keep a Napalm Zombie alive.

Start another eclipse and go into the tunnel near the MPL. Find the gas pipe beside one of the Pack-a-Punch pressure plates.

Turn its wheel four times.

Gas will begin leaking through the tunnel.

Lead the Napalm Zombie through the tunnel so its fire ignites the gas leaks along the route toward the power room.

Then return to the pipe and activate the raised lever during the same eclipse.

6. 💦 Plug the four holes

Purchase Spikemores and start another eclipse.

In the MP5K tunnel you’ll find four holes in the wall.

Position the Spikemores so their spikes are directed toward the holes, then have zombies trigger them. You want the spikes to lodge into and plug all four holes.

After all four are plugged, go to the waterfall and interact with the brick marked:

“Do Not Hold X”

Yes—you actually hold X / Square on it.

The increased water pressure completes the step.

7. 🔲 Activate the 12 wall panels

Start another eclipse.

There are 12 rectangular panels around the map. Melee all twelve; order doesn’t matter.

A useful location breakdown is:

5 Spawn
2 Mud Room
2 Stakeout area
2 Minecart area
1 near Power

Once all 12 are activated, go toward the top of the minecart area. There’s a wooden snare/trap outside the playable area.

Destroy it with an explosive.

You’ll hear dialogue confirming success.

8. 🔢 Mud Room code — 16 • 1 • 3 • 4

Interact with the radio near the minecart area after the previous step, then start another eclipse.

Go to the Mud Room and find the four giant stone dials.

The code is:

16 — 1 — 3 — 4

The symbols represent numbers:

• = 1
I = 5
C = 10

So 16 = C + I + •

Set the four dials correctly and you’ll get dialogue confirming that the code worked.

9. 🔔 Find the four correct gongs

You’ll need the Pack-a-Punched Baby Gun — the Fractalizer.

Start an eclipse.

There are multiple gongs around Shangri-La, but only four are correct.

Melee a gong and watch the crystals:

🔴 Crystals turn RED = wrong gong

Find the four correct gongs. When you’ve activated all four, the crystals will glow and you’ll see a Treyarch symbol.

10. 🧨 Get the dynamite

Go to the crystal near the minecart geyser. You’ll see dynamite hanging from it.

Shoot the crystal with the Fractalizer.

The energy bounces between the crystals and knocks the dynamite loose.

⚠️ Have somebody underneath it to catch it.

If you miss it, you’ll need to repeat that portion.

11. ☄️ Shrink the giant meteor

While the correct gongs/crystals are activated during the eclipse, look above the Mud Room for another crystal.

Shoot it with the Fractalizer.

The energy ricochets through the crystals and eventually hits the enormous meteor above Pack-a-Punch, shrinking it.

12. 🧨 Give Brock & Gary the dynamite

Activate Pack-a-Punch by having players stand on the four pressure plates.

Go all the way up the Pack-a-Punch stairs.

Instead of the normal machine, you’ll be able to approach the wall at the back.

Wait for the dialogue, then the player carrying the dynamite interacts with the hole in the wall to hand it over.

The dynamite blows open the wall.

13. 💎 Grab the Focusing Stone

Return to the present.

Activate the four Pack-a-Punch pressure plates again and go back upstairs.

You’ll now find the Focusing Stone.

Pick it up.

🏆 TIME TRAVEL WILL TELL — COMPLETE!

All four players get the achievement/trophy, while the player who actually picks up the Focusing Stone receives all seven BO1 perks, which remain through downs/deaths for the rest of that game
