Explorers vs Entities
Don't scream. It's listening.
Up to four explorers walk into a haunted house with a flashlight, a camera and very little time to film evidence, solve its puzzle and get out with the loot. One entity waits inside. The twist: your sanity breaks from what you really do in front of the screen.
- Unreal Engine 5.4 · C++
- 1–4 explorers vs 1 entity
- Built solo
Sanity measures your real fear
Your microphone is live. Scream and the entity hears you. Run, stand in the dark or turn your back on a room, and your sanity drops. Everything a frightened person does brings you closer to breaking.
The explorer never sees their own sanity; they only feel it as shaking hands and dropped objects. The entity sees it over every head and knows exactly when to strike. Recovering costs dearly: you close your eyes and breathe, blind while it hunts you.
Key features
Proximity voice chat
Your friends only hear you when you are close, and so does the entity. Group up from the menu and go in together.
Loot that persists
Five rarities, an inventory, a shop and gear that carry over between matches. Die, and you lose everything you were carrying.
20+ puzzles, a different one each match
Sequences, codes, items to find and carry. Every night draws a new one, so a house never plays the same twice.
The maps
The house
The first map: a large furnished house where the evidence moves every match.
The abandoned hospital
Two floors at night, with its own clues, loot and puzzles.
The Hampel Mansion
Four floors from cellar to attic, a garden all around and a puzzle in several stages. Traced from plans hand-drawn by the architect Nicolas Hampel.
The Quinta Orsini
A perfumers' villa under a storm that never stops: a chapel, a tower with a lightning rod, a greenhouse, a privet maze with a gazebo, and the family pantheon with its crypt.
The boarding school
A nuns' boarding school closed for decades: a cloister around a well, a chapel with a choir, the bell tower and, below, the vaulted crypt, the ossuary and the cemetery.
Under the hood
One developer, AI-assisted workflows, and the engineering habits of a product team.
Unreal Engine 5.4, C++ first
Gameplay, sanity, entities and UI live in C++, across more than 500 source files.
Online multiplayer
Replicated gameplay over Steam networking, with friend groups and proximity voice chat.
AI opponents and allies
AI-driven entities and bot explorers make solo play possible on both sides, on every map.
Maps as code
Layouts are Python data, validated and built into Blender by script, then dressed in Unreal by re-runnable tools. A map can be rebuilt from scratch.
Automated tests
Over 100 Unreal automation test files, plus smoke tests that launch the packaged game on each map before a release.
Versioned releases
Tagged builds with release notes and screenshots for every version, published here automatically.
Coming soon to Steam
Early Access is planned with five maps, four entities and 1–4 explorers per match. The game is in Spanish for now.
Latest updates
Every version, newest first, with what changed and how it looks. Release notes are written in Spanish.
