Mysteries That Remain Unsolved in Popular Games

6 September 2026

Ever sat back with your controller or mouse, staring blankly at your screen, thinking, “What the heck just happened?” Yeah, we've all been there. As gamers, we’ve unraveled epic storylines, conquered unbeatable bosses, and discovered secret areas—but some questions keep bugging us long after we’ve seen the credits roll.

Some gaming mysteries are so well-crafted (or just plain bizarre) that they’ve kept entire communities guessing for years. From cryptic messages and hidden characters to unexplained events and eerie NPC behaviors—there are just some things we can’t figure out. And maybe that’s the point.

Let’s take a trip down the rabbit hole into some of the biggest, most mind-bending, and totally unsolved mysteries in popular games. Fair warning: you might leave this article with more questions than answers.

1. The Mount Chiliad Mural – Grand Theft Auto V

Let’s kick things off with what might be the most famous unsolved gaming mystery of all time: the Mount Chiliad mural in GTA V. If you’ve played this game (and let’s be real, who hasn’t?), you’ve probably seen the bizarre drawing in the cable car station atop Mount Chiliad.

The mural features strange symbols—UFOs, an egg, a jetpack—along with a pyramid-like structure and question marks. What does it all mean?

The UFOs and Jetpack Theories

Players have found UFOs in the game after completing it 100%, which matches the mural’s hints. But the jetpack? That’s still a mystery. People have tried everything—completing the game under certain weather conditions, finishing it without dying, entering cheat codes, you name it.

Rockstar has never confirmed if the mural leads to anything concrete, and that just fuels the fire even more. Is it a red herring? A tease for future DLC? Or is there still something hidden deep in the game’s code?

2. The Forbidden Door – Demon’s Souls

Ah, FromSoftware. Masters of making players suffer—and ponder.

In the 2020 remake of Demon’s Souls, players found a new door that wasn’t in the original PS3 version. This door was locked, and no one could figure out how to open it. Naturally, the community went wild.

A Challenge Worthy of a Soulsborne Game

It turned out that players had to collect a whopping 26 mysterious "ceramic coins" and trade them with a crow for a key. Inside? A room with... some armor. Yep, that’s it.

But here's the thing: why go through all that for such a minor reward? Was it just a fun Easter egg, or was Bluepoint trolling us? Was there more planned? The room is cool, sure, but after all that effort, many are still convinced there’s more to find—or that something was removed before release.

3. The Secret of Lavender Town – Pokémon Red & Blue

Cue the eerie chiptune music and prepare for a wave of nostalgia (and maybe a few childhood nightmares). Lavender Town is infamous for being the creepiest place in the Pokémon universe. But over the years, urban legends have turned it into something even darker.

The Lavender Town Syndrome Legend

There’s a creepy pasta (internet horror story, for the uninitiated) that claimed the original music caused psychological effects in children—like depression, anxiety, and even worse. Of course, it’s all urban legend stuff, but what’s fascinating is how the myth keeps living on.

Combine that with the mysterious ghost in the Pokémon Tower that says, “Get out…” before you can identify it, and you’ve got a recipe for full-blown gamer paranoia. No other town, in any Pokémon game, has sparked this kind of morbid curiosity.

4. Mysterious Crying Baby – Assassin’s Creed II

Ubisoft packed Assassin’s Creed II with secrets, but one of the weirdest? A crying baby sound hidden near an alley in Venice.

Whose Baby Is It?

There’s no quest, no NPC, no explanation—just the faint sound of a baby crying. It’s been there since the game launched. Some fans even speculated it was a bug, while others think it’s a nod to some secret lore or a developer’s inside joke.

Is there a more tragic or hidden story connected to the location? Maybe a mission that got scrapped during development? No one knows, and no official statement has ever been made.

It’s a tiny, unnerving detail, but one that sticks with you. Like seriously, why is there a baby crying in a back alley for no reason?

5. The Merchant’s Past – Resident Evil 4

“Welcome, stranger!”

If you've played Resident Evil 4, you probably remember the mysterious, trench-coat-wearing merchant who pops up randomly throughout the game. He sells you weapons, upgrades, and items—but who is he?

Friend, Foe, or Something Else?

We don’t know where he comes from, why he’s helping Leon, or how he moves from place to place so quickly. Even more mind-boggling: why do there seem to be multiple merchants... or is it the same guy teleporting?

Capcom has never given us a proper backstory. The merchant remains one of the most iconic yet unexplained characters in gaming history. Some fans think he’s infected but not hostile. Others believe he’s part of a forgotten subplot. All we know is… we trust him with our lives—and all our pesetas.

6. Who is Gaster? – Undertale

If you thought Undertale was weird the first time through, wait till you try digging into its hidden content. And at the center of all that lore is one name: W.D. Gaster.

The Ghost in the Game

Gaster isn’t part of the main story, but he shows up through super rare RNG (like, 1 in 100 chance-level rare). Players who encounter special NPCs talk about a scientist who "fell into his creations"—and poof, was erased from existence.

Some believe Gaster is the creator of the universe. Others think he’s responsible for the game’s meta-narrative. But the real kicker? Even the game’s files are cryptic, packed with Gaster-related gibberish. It’s like Toby Fox wants us to lose sleep over this.

Spoiler alert: it’s working.

7. Is There Still More to Find in The Legend of Zelda: Breath of the Wild?

You’ve probably sunk countless hours into BOTW, and you might think you’ve seen everything. But what if I told you there might still be secrets hiding in plain sight?

The Unfound Chests and Unused Dialogue

Dataminers have uncovered unused event triggers and chest placement data that doesn’t match anything in the final game. For instance, there are treasure chests nobody has found through normal play. Nintendo hasn’t confirmed whether it's leftover code… or if something’s still out there, waiting to be unearthed.

With over 900 Korok seeds and a truly massive map, it’s not hard to believe something significant might still be hiding—somewhere.

8. The Secret Computer – Batman: Arkham Asylum

Here’s an example of a mystery that was solved… six months too late.

When Arkham Asylum came out, there was a locked wall in the warden’s office that didn’t seem to do anything. Turns out, behind that wall was a secret room containing blueprints hinting at the sequel, Arkham City.

Rockstar’s Little Secret

The devs kept the secret so well-hidden that nobody found it. In fact, Rocksteady had to tell people about it themselves during an interview. To this day, it makes us wonder how many other secrets they could’ve hidden—and whether players simply never found them.

It’s kind of cool and kind of infuriating. Like, are there mysteries so well-hidden that even speedrunners and obsessive fans haven’t figured them out?

9. The Tunnels Beneath Los Santos – Grand Theft Auto V (Again)

Yep, GTA V gets two entries because it’s just that layered.

Many players have reported oddities in the underground tunnels of Los Santos—strange sounds, flickering lights, and hidden rooms with unclear purposes.

Are Aliens or Cults Involved?

Some believe these tie into the Mt. Chiliad mystery. Others think the Epsilon Program (the weird in-game cult) is somehow involved. A few even claim to have seen shadowy figures.

Whether it’s part of unfinished content, creative Easter eggs, or just player imagination running wild—no one knows for sure. But the community remains obsessed, and new “sightings” pop up all the time.

10. The Never-Released Areas – Elden Ring

From the Lands Between to the foggiest corners of the map, Elden Ring is filled with secrets. But some areas have entrances, load zones, or references in the game files—with no known way to access them.

Are These Future DLCs or Unfinished Realms?

Dataminers have found names of zones, cryptic references, and even enemy types that don’t appear anywhere in the game. Some of it could be cut content. But could it be that FromSoftware is teasing us, preparing entire areas for future DLC—or layering in more mysteries we haven’t unraveled?

Given their history (looking at you, Bloodborne), we wouldn’t put it past them.

Final Thoughts: Maybe Some Mysteries Are Meant to Stay That Way

Every one of these mysteries adds something special—something extra—to the games we love. They keep us talking, theorizing, and coming back for more, even years after release.

Maybe some questions won’t ever get answers. And maybe that’s okay. Because at the end of the day, it’s the wonder, the curiosity, and the chase that make gaming such a magical experience.

So the next time you stumble on something strange in a game, don’t shrug it off. Take a screenshot. Make a note. You might’ve just taken the first step into solving the next big unsolved mystery.

Or, y’know, started a whole new one.
