You know the sound. That iconic, space-age *pew-pew-pew* that echoed through the halls of Kino der Toten and the swamps of Shi No Numa. It’s the sound of salvation. The sound of a Pack-a-Punched Wunderwaffe. The sound of the Ray Gun.
For years, that weapon has been the white whale of Zombies players everywhere. The ultimate get from the Mystery Box. The one thing that could turn a desperate last stand on round 28 into a triumphant victory lap. I can still feel the palpable jealousy when my buddy would get it on his first spin and I’d be stuck with the Ballistic Knife. Again.
But what if I told you that in Call of Duty: Mobile's Zombies mode, there's more than just luck involved? What if I told you there’s a way to earn a permanent, breathtakingly cool skin for the Ray Gun itself? Not through a lucky draw, not by dropping a fortune on COD Points, but through sheer grit, discovery, and a bit of in-game detective work.
Yeah, I thought you might be interested.
Forget Rumors: The Aetherium Crystal Ray Gun is Real
Let’s get one thing straight. This isn’t a myth. It’s not some elaborate playground rumor that got out of hand. The Aetherium Crystal Ray Gun skin is 100% real, and it is arguably one of the coolest, most exclusive cosmetics in the entire game. It wraps the classic weapon in a shimmering, purple-hued crystal that pulses with dark energy. It’s… well, it’s gorgeous.
But you don't just *get* it. You earn it. And the process is one of the most elaborate and rewarding hidden quests the CODM developers have ever slipped into the game. This isn't about grinding points or battle pass tiers. This is a classic, old-school Easter egg, a puzzle box waiting to be solved right in the middle of a zombie apocalypse.
And honestly? The frustrating thing about it for the longest time was how secretive it was. For months, it was just whispers on Reddit and fragmented videos from obscure YouTubers. No one seemed to have the full picture. It took a genuine community effort to piece it all together, which, in a way, makes the reward feel even more special. It's this kind of player-driven discovery that keeps gaming communities alive and thriving—it's a bit like how fans are already picking apart every tiny detail from the recent AC Shadows AMA, trying to see the bigger picture.
The CODM Zombies Hidden Easter Egg: Your Step-by-Step (and Sanity-Saving) Breakdown
Alright, deep breath. Before we dive in, let me be clear: this is tough. It requires patience, a bit of luck with zombie spawns, and maybe a friend or two who won’t lose their cool when you mess up the sequence for the fifth time. I've been there. My squad and I spent a whole weekend fueled by nothing but coffee and sheer stubbornness to crack this.
You’ll be doing this on the Shi No Numa (Undead Siege) map on Hard difficulty. Don’t even bother on Normal; it won’t work. The goal is to find and activate a series of hidden symbols in a very specific order, all while a literal army of the undead is trying to eat your face.
Simple, right?
Step 1: The Initial Hunt & The Blueprints
First, you need to find the five broken parts of a blueprint scattered around the map. They’re in set locations, but they glow with a faint blue aura that can be easy to miss in the chaos. One is in the Fishing Hut, another in the Doctor’s Quarters, one in the Comm Room, one in Storage, and the last one is in the main hut where you start. You have to physically interact with each one. This is the easy part, a little warm-up for what’s to come.
Step 2: The Ghost in the Machine (The frustrating part)
This is where things get… tricky. After collecting the blueprints, you need to head to the central building. There’s a radio in there. Interacting with it will trigger a voice line—a distorted message. Pay attention! This message contains your code. It’s a sequence of numbers. Write it down. Seriously, don’t try to remember it.
Now, you have to find several TVs scattered around the map. When you approach them, they’ll flicker and show a single number. You have to shoot the TVs in the *exact* order given by the radio message. If a zombie smacks you and you shoot the wrong TV, the sequence resets. If you take too long, it resets. This is the step that breaks people. My advice? Have one player dedicated to kiting the zombies away while another focuses solely on the TV sequence. Communication is everything.
Step 3: The Secret Boss & The Aether Crystal
If you successfully shoot the TVs in the right order, a new waypoint will appear on your map, leading you to a previously inaccessible area. A portal will open, and from it will emerge a special boss—a super-powered Abomination. This thing is way tougher than the normal ones. It has more health, hits harder, and just generally seems angrier about its existence.
Your entire squad needs to focus fire on this beast. Once you take it down, it will drop a unique item: a glowing Aetherium Crystal. Pick it up. That's your key.
You then take this crystal to a specific workbench in the Doctor’s Quarters. Interacting with the bench will trigger a short animation, and bam! A pop-up confirms you’ve unlocked the skin. It’s a moment of pure, unadulterated triumph.
More Than a Skin: It's a Badge of Honor
Look, is this a lot of work for a cosmetic? Absolutely. You could spend the same amount of time grinding camos for five other guns. But that's not the point. The Aetherium Crystal Ray Gun isn't just a skin; it's a story. It's a testament to your dedication and your ability to solve a puzzle under extreme pressure.
When someone sees you running around with that thing, they know you didn't buy it. They know you earned it. You went through the wringer, deciphered the code, slayed the secret beast, and came out the other side. It’s a quiet nod of respect from one Zombies veteran to another.
The grind can be so intense that some nights you might just want to shut it off and do something else. No shame in that. Go play a few rounds of chess online or find some fun 2 player games to decompress. The undead will be waiting for you when you get back.
FAQs: Your Burning Questions About the Ray Gun Skin Easter Egg
How tough is this Easter egg to do solo?
I’m not gonna lie to you—it’s borderline impossible for the average player. While technically doable, juggling the TV sequence while simultaneously managing a horde of Hard-mode zombies is a nightmare. The step with the secret boss is also scaled for a team. I strongly, *strongly* recommend grabbing at least one friend.
Do I need specific perks or weapons to even attempt this?
There are no hard requirements, but you can make your life a lot easier. Having Speed Cola for faster reloads and Juggernog for survivability is a no-brainer. For weapons, you’ll want something with high mobility for running between TVs and a high-damage weapon like a shotgun or LMG for the boss. And obviously, if someone on your team gets a Ray Gun from the box early… that’s a sign from the universe.
I heard you can only do this during a special event. Is that true?
This is a common misconception! This Easter egg is a permanent part of the Shi No Numa map in Undead Siege. It's not tied to any seasonal event or limited-time mode. You can attempt it anytime you want, which is great because you'll probably need more than one try. Trust me. Some nights you'll fail so many times you'll just want to play a simple distraction like Save the Doge to feel a sense of accomplishment.
What’s the best strategy for the final part of the CODM Zombies hidden Easter egg?
For the secret Abomination boss, it’s all about coordination. Don’t all bunch up. Have one person use a weapon with the slowing ammo mod to kite the smaller zombies away. The other players should focus all their fire on the Abomination's glowing heads when it opens its mouth to attack—those are its critical spots. Use your operator skills and any explosives you have saved up. Don't be a hero, just pour on the damage.
Can I lose the skin after I unlock it?
Nope! Once you successfully complete the Easter egg and see that unlock notification, the Aetherium Crystal Ray Gun skin is permanently added to your account. It's yours forever. A permanent trophy for a hell of a challenge.
