Aboard the Reuss Express, an assassination derails a journey on the eve of heiress Lady Unterwald’s landmark speech. A straight-laced lawyer, a rookie detective who writes crime novels, and an undercover spy become entangled in the murder mystery, with the killer somewhere among the passengers. The 1930s steam train is both the setting and the confined stage for the trio’s effort to prove their innocence.
Players take control of Diana, Arthur, and Herman in an interlinking comedy adventure. Its central activity is point-and-click, item-based puzzle solving, alongside meeting the train’s quirky and suspicious passengers. Twists and slapstick humor shape the mystery, while an in-game telephone hint line offers a nudge when needed. The detailed pixel art, full voice acting, and original soundtrack further define its presentation.
The game supports either direct character control with a controller or a classic mouse-and-keyboard experience, giving players a choice in how they interact with its puzzles and characters.
