Looking for a Halloween scare? Take a trip into the bowels of the Château de Thoiry, and try to prevent a zombie invasion in the heart of the family crypt, where beings that are no longer human are on the prowl, during an escape game that will require a lot of courage. Will you dare to live this adventure?

Are you ready for an immersiveescape game in the depths of a castle in the Yvelines? Right next door to the family-friendly Thoiry Zoo is the Château de La Panouse, owned by the de La Panouse family since 1559, and a treasure trove of secrets... If last year you had to plunge into the darkness of the family crypt and escape a sinister voice, this year you'll have to prevent the spread of a terrible virus - and you've only got until November 2, 2025!

Accessible to players aged 12 and over, this escape game is for the bravest among you! It's also an opportunity to discover an exceptional and highly charged site beneath the château, in the historic cellars, in teams of 3 to 8 players, who you'll have to choose carefully if you want to come out alive and, above all, whole! For an hour, you'll have to solve riddles, puzzles and face a few surprises...

Your mission? Prevent a zombie invasion. A virus of unprecedented virulence has hit the Château de Thoiry, and the staff have been hard hit. In the space of a few days, several employees showed symptoms of a terrifying disease: uncontrollable aggressiveness, cannibalistic tendencies and rapid tissue decomposition. The disease spread rapidly. The authorities isolated the sick in the castle's old crypt, a forgotten area. But nothing seems to be able to stop the epidemic. The only solution: find the mother strain.
