In Paris, Halloween often means a costume party or a bar decorated for the occasion. For a change of pace, head to Cergy or Sénart, about an hour from the capital, where the Koezio indoor adventure park offers a special mission during the fall break. From October 26 to November 1, “Agents d’Élite” becomes “Agents d’Élite: CREATURES,” and the atmosphere is anything but a simple family outing.
A forbidden laboratory hidden beneath the park

Whether in Cergy, in the Val-d’Oise, or in Sénart, in Seine-et-Marne, the story is the same. For years, Dr. Ego conducted forbidden experiments in a laboratory hidden beneath the Koezio complex, performing genetic manipulations on both humans and animals, until the day everything changed. The creatures have escaped, the laboratory is under quarantine, and your team is the only one still capable of intervening.
The mission unfolds in four acts. First, you must prevent the creatures from leaving the complex, then move through the facilities to regain control of the various zones. Next, you must reach the laboratory and put an end to Dr. Ego’s experiments. And once the threat is contained, you still have to find your way out.
On October 30 and 31, the mission shifts into high gear

For the biggest thrills, come on October 30 and 31. Actors are integrated into the tour, and sessions run until midnight. You might not be alone in certain areas.
The mission is played with teams of two or more people and is open to participants 1.40 meters and taller, for safety reasons. It’s perfect for a duo, a group of friends, or a family with teens. The park’s other activities, including karaoke, remain open every day during the school break, so you can extend your outing once the mission is complete.
