The player lands on the campaign site and watches footage of the stunt that frames the game: a scale model of the Nouveau Grand C4 Picasus, lifted by a helium balloon roughly 35 km into the stratosphere and filmed against the curve of the planet.
- 2
After the video, the player is dropped into an interactive 3D star map, a Google Sky Map-style atlas depicting the space the car footage was shot in.
- 3
The player looks around this starfield with mouse or touch on desktop, or by physically tilting a tablet or phone to pan the view via the gyroscope; the whole scene runs in-browser with no app install.
- 4
The core loop is a search-and-find: the player scans the sky to spot the car hidden among the stars.
- 5
Locating and centering on the car ends the session and rewards the player with a personal passcode.
- 6
The passcode is redeemed offline at a Citroën dealership, tying the digital find to a real-world visit, and also enters the player into a linked prize draw.
- 7
Depending on the code, the reward is either reimbursement on a purchased Nouveau Grand C4 Picasso or one of 200 Samsung Galaxy Tab tablets, with participation tied to a car purchase.
Objective
Citroën built StratoQuest to launch the new Grand C4 Picasso and carry the TV campaign's 'discover the world inside' idea — an origami Earth, a journey into space — into a digital experience. The goal was to turn passive viewers into active participants who would engage with the car on their own phones and tablets, then convert that curiosity into dealership visits through an in-person prize redemption. The grand prize, a full refund on the car itself, was aimed squarely at rewarding early buyers.
Solution
StratoQuest opens as a browser-based star map, no app download required. On desktop you pan around with the mouse; on a phone or tablet you tilt the device itself to look up, down and around a 3D night sky, the way you'd swing a telescope. Somewhere among the stars is the Grand C4 Picasso, actually flown to the edge of the stratosphere and filmed from its own balloon-borne camera rig — the player's task is to hunt it down against the real footage of Earth from above. Spotting the car reveals a redemption code, which then has to be taken in person to the nearest Citroën dealership to claim a prize. Play itself was reserved for people who had already bought the car, turning the hunt into a reward for buyers rather than an open sweepstakes.
