You start on a chilly sidewalk in downtown Billings, phone in hand, the distant rumble of the Yellowstone River undercutting the city’s talk. The audio drops you into Commander Mahoney’s case file and the streets become an interrogation room: alleys that remember the railroad, storefronts that keep secrets, and Rimrocks visible on the skyline like watchful cliffs.
Billings grew up with the Northern Pacific Railroad and the river that powered its growth; the downtown grid still shows that mercantile, oil, and western-heritage past. Geologically, the Rimrocks — layered sandstone and ash from ancient volcanic activity — frame the city, giving compact vistas from higher streets. Culturally the town blends ranching and energy-industry culture with an emerging craft and food scene around Montana Avenue.
Practically, the experience is an app-driven audio game of about 2.5 hours with ten mapped stops. Choose the walking map to move through downtown blocks on foot or the driving map to follow scenes farther out. The app delivers 16 voiced characters, timed clues, and a scoring system that evaluates your deductions. You’ll park or pause at each waypoint, listen, collect evidence, and commit to an arrest warrant when the pieces fit.
Bring a charged smartphone, earbuds, and comfortable shoes; plan for daylight hours so you can read signs and photos. The route is flexible — take breaks, trade devices, or play hard mode for tougher puzzles. Expect urban sidewalks, brief street crossings, and an immersive audio narrative that turns Billings’ streets into a murder board.
