Secret Signs as Level design tool
Have you ever spotted a strange mark on a wall or a small symbol carved into a door in a video game?
Chances are, you’ve come across what we call Secret Signs. These subtle clues are placed by game designers to communicate vital information — like the presence of traps, hidden loot, or safe zones — without resorting to big glowing arrows or heavy-handed tutorials.
They’re part of a larger concept called environmental storytelling, where you learn about the game world simply by paying attention to your surroundings.

Why Do Games Use Secret Signs?
Secret Signs come in handy for several reasons:
🞿 Navigation: They help point the way to important items or shortcuts.
🞿 Storytelling: By using symbols, designers can suggest historical or cultural details about the world.
🞿 Gameplay: They offer hints about upcoming dangers or highlight resources you might need.
🞿 Atmosphere: They make the world feel more alive and worth exploring, rewarding players who notice the little things.

Real-Life Inspiration: Hobo Symbols
It might surprise you that these ideas aren’t limited to video games. In the early 20th century, traveling workers in the United States — known as hobos — came up with a simple system of chalk or charcoal marks on fences and walls. These hobo symbols were a kind of “survival code,” warning fellow travelers about rough property owners or police patrols, and indicating spots where one might get food or safe shelter.
These symbols were easy to draw and erase, and they often changed meaning depending on context — yet anyone familiar with the system could quickly understand them. Though hobo symbols have mostly disappeared from everyday use, they remain an intriguing piece of American folklore and serve as an excellent real-life parallel to in-game Secret Signs, illustrating how a simple visual code can foster hidden communication and mutual aid.
At their core, these humble markings speak to a profound human instinct to look out for one another even under the harshest conditions. A quick slash or dot, scrawled in a moment of need, became a lifeline for someone they’d never meet, a silent promise that help could be found just around the bend. That spirit of solidarity, born from necessity and creativity, lives on in modern game design: when you spot that subtle arrow etched into a crumbling wall or a tiny glyph tucked into a shadowy corner, you feel a quiet connection to the world’s architect and to every other player who’s paused to decipher the clue before you.

Three Games That Use Secret Signs
Fallout 4: Railroad Signs
In Fallout 4, you’ll come across chalk markings made by the Railroad, a secretive group in the post-apocalyptic ruins of Boston. They use these chalk signs to:
🞿 Stay Covert: It fits their role as an underground faction avoiding the watchful eye of the Institute.
🞿 Guide Players: Follow the symbols to discover safe houses, resources, or alternate paths.
🞿 Deepen the Lore: The subtlety of chalk marks on crumbling walls brings a sense of realism to the war-torn setting.

Skyrim: Thieves Guild Shadow Marks
Long before Fallout 4’s chalk symbols, The Elder Scrolls V: Skyrim introduced the Thieves Guild Shadow Marks, which might be among the earliest and most memorable secret sign systems in gaming. Carved on building exteriors or tucked away in corners, each mark has its own meaning:
🞿 Guild: Thieves Guild presence.
🞿 Safe: A secure spot for resting or stashing items.
🞿 Danger: A heads-up about traps or tough enemies.
🞿 Escape: An alternate way out if you need to flee.
🞿 Protected: Property under Guild protection (don’t steal here).
🞿 Fence: A place to sell stolen goods.
🞿 Thieves Cache: Barrels containing special items that appear as you progress in Guild quests.
🞿 Loot: Valuable items nearby.
🞿 Empty: No need to bother; nothing worthwhile inside.
These symbols reinforce the idea that the Thieves Guild is woven into city life. They also make players feel clever when they interpret marks on their own.

S.T.A.L.K.E.R. 2: Zone’s Secret Signs
In the S.T.A.L.K.E.R. 2, graffiti-style marks scattered around the Zone let you know where to find caches, dodge anomalies, or simply brace for danger. They deepen the ominous atmosphere:
🞿 Survival Focus: Life in the Zone is dangerous, so these cryptic signs feel right at home.
🞿 Reward Curiosity: If you see a suspicious marking, it might be worth checking the area more carefully.
🞿 Amplify Tension: Eerie scribbles on abandoned walls underscore the series’ bleak and mysterious tone.

Why Do Games Use Secret Signs?
A big reason is the psychological boost players get from discovering something that isn’t highlighted by a tutorial or in-game prompt. Figuring out a sign’s meaning — then using that knowledge to avoid a trap or find hidden loot — creates a rewarding sense of agency. Even though developers intentionally place these clues, they still feel like personal discoveries.
Tips for Designing Secret Signs
If you’re a developer looking to create a system of Secret Signs, consider the following:
🞿 Consistency: Keep the visuals and rules of the sign system uniform across the game.
🞿 Lore-Friendly: Make sure each sign fits the game’s story and atmosphere.
🞿 Balanced Visibility: Players should be able to spot them without feeling like they’re being spoon-fed.
🞿 Clarity: Use simple icons and shapes that naturally suggest their meaning.
🞿 Moderation: Don’t overuse them; leave some mysteries for players to find on their own.
🞿 Purpose: Make sure each sign has a clear reason for existing — whether it’s directing players or warning them.

Gathering Player Feedback
It’s always smart to test how players interpret and notice Secret Signs:
Isolated Symbol Tests: Show the icons without context and see if people guess the right meaning.
In-Game Testing: Hide them in a test level and ask players if they saw them, understood them, and found them helpful.
If players consistently miss a sign or misinterpret it, adjust its design or placement. Early testing can save you from major headaches later.

Conclusion
Secret Signs lend an extra layer of depth to any game world. From the chalk scribbles of the Railroad in Fallout 4 to the carved glyphs of the Thieves Guild in Skyrim, they reward players who pay attention to small details. Real-life examples — like the hobo symbols used by traveling workers a century ago — show that hidden marks can serve as a universal language of survival and cooperation.
With thoughtful design and a bit of experimentation, Secret Signs can make your game more immersive, encourage exploration, and help players feel like they’re uncovering a world of hidden stories. After all, there’s no thrill quite like stumbling on a cryptic sign and realizing it leads to a treasure — or a trap — you never would have found otherwise
