New leadAt the heart of this interactive experience is the disappearance of the Golden Sheep, a unique artwork by the renowned Chinese artist Dǎliè Gǎngkǒu. After an official visit he gave the statue, a symbol of connection, to the city. Shortly after, it vanished without a trace from the city museum.
The police recovered part of the collection, but the most important piece is still missing. It’s up to you, the citizen investigators, to unravel the mystery undercover and find the Golden Sheep.
Dossier Lier is an intense city game where mystery, teamwork and local heritage come together in a gripping storyline. You become part of a fictional but believable police file, in which Lier isn’t just the backdrop: the city plays the lead.
You go on patrol past several suspicious locations in and around Lier, looking for clues that bring you closer to the truth behind the art theft.
Up to six teams of at most seven players each ride through the city at the same time, with a fatbike and an investigation file. Every group follows its own route, but only by working together can you solve the whole file.
