Escape… if you can.
Halloween Nights 2025 at Koezio Cergy
On October 30 and 31, Koezio Cergy transforms for two exceptional nights.
An ancient cult has taken over the place… Step into a dark, abandoned world with a mysterious, oppressive atmosphere where every corridor, every shadow, every whisper draws you closer to the final ritual.
Challenges and puzzles await you at every step of your journey. Gather your best team for a unique – and truly intense – experience. But… will you dare to cross the doors of the building? Limited spots… and the cult is waiting for you. Event not recommended for under 12s.
You Have Been Summoned
This year, Koezio turns into an abandoned place, forgotten by all, plunged into a mysterious and oppressive urban-exploration atmosphere.
You did not choose to be here: you were summoned by an ancient and unsettling cult.
The moment you step inside, you realize you are not here to play… but to be sacrificed.
Your faces are watched, your steps followed, your presence expected.
Your goal? Escape.
But the building is alive – it shifts, it traps, it tests you.
Cooperate. Escape.
District after district, the building puts you to the test — from dizzying high-level courses to puzzles to solve, traps to avoid, and challenges to overcome. You play in a team of 2 to 5 players: your only chance of survival is to cooperate and join forces to outsmart the macabre traps. Only true teamwork will allow you to see the light of day again. Time is ticking. You will have about 1h30 to make it out. And don’t forget… you won’t be alone. You will be watched.
