Project Undercover Escape Game for Businesses

What awaits you.

Adrenaline surges, time is ticking... Your teams are plunged into a top-secret mission to thwart a conspiracy. Success hinges on their unity and ability to act as an elite intelligence unit. A race against time to save the world. This is one of our corporate investigation games: 1h30 to 2h, for 20 to 300 participants.

This espionage adventure is designed to foster cooperation, boost problem-solving skills, and enhance communication under pressure. Each member will play a crucial role in achieving a common goal, forging unbreakable bonds.

  • Decrypt clues to progress through the investigation.
  • Collaborate to thwart the enemy's plans.
  • Trust each member for collective success.

Price of a Project Undercover Escape Game

Expect €44 to €73 excl. VAT per person in the Île-de-France region, with a minimum charge of €2,190 excl. VAT for twenty-one to thirty participants. The per-person price then decreases: €73 for thirty, €58 for one hundred, €44 for two hundred.

Île-de-France pricing tiers: €2,590 excl. VAT for up to forty people, €2,990 for up to fifty, €4,890 for eighty, €5,790 for one hundred, €7,490 for one hundred and fifty, and €8,890 excl. VAT for two hundred. Beyond two hundred participants, pricing is provided upon quote.

Outside the Île-de-France region, the pricing starts only from forty-one participants: €3,790 excl. VAT for fifty and €6,590 excl. VAT for one hundred in the Hauts-de-France region. Below this number, and in other regions, pricing is provided upon quote. Calculate your exact price based on your group size and location.

Organising a Spy Escape Game for a Seminar

Project Undercover is the investigation format that accommodates the largest number of participants in its category: up to three hundred people divided into operational units, competing for a common ranking.

This makes it ideal for conventions and multi-site seminars, where everyone needs to be engaged simultaneously without running separate activities. The shared mission also provides a reason to mix departments.

For a corporate seminar, it fits perfectly in the afternoon: the briefing sets the scene, the investigation occupies the main part of the slot, and the final ranking serves as a transition to the evening.

Venue, Equipment, and Schedule

A meeting room is sufficient, either in your offices or at your seminar venue. The activity takes place indoors and requires no specific location.

We bring and set up all the equipment: agent briefcases, confidential documents, decryption tools, and immersive sound system. You don't need to prepare anything.

The schedule includes the briefing and team allocation, progressing through the investigation zones, tackling puzzles that highlight complementary skills, followed by the final ranking and prize ceremony. Count 1h30 to 2 hours. Within the same timeframe and using the same setup, the cybersecurity escape game transposes the scenario into a digital context.

Participant Numbers and Profiles

From 20 to 300 participants, in teams of 5 to 7 people. Please note before budgeting: the pricing scale ends at two hundred, and quotes are provided for numbers above that.

No espionage expertise is required. The puzzles rely on logic, observation, and common sense, and the mission can only be solved by sharing information: withholding it costs the group time.

The format encourages rotating leadership, with each team needing to listen to whoever holds the solution at any given moment. For a corporate event bringing together several hundred people, this is one of the few investigation games that can scale to this size. Many companies hesitate between this and Murder Party – Coup de fil.
