You step off the market square and the city rearranges itself into clues: cobbles that shift underfoot, the Belfry watching like a patient jury, alleys that dare you to choose a direction. The Walter Case drops you into Mons as a ticking investigation—an imagined blackmail spirals into a race to find a hidden bomb within 150 minutes. Your phone is the only badge you need; choices you make alter the route, suspects, and puzzles.
