Famicom Detective Club: The Two Case Collection bundles both remade entries in Nintendo's classic mystery adventure series: The Missing Heir, in which an amnesiac detective uncovers a wealthy family's dark secrets, and The Girl Who Stands Behind, a prequel about a schoolgirl's murder tied to a ghost story.

Investigation-driven gameplay across both stories has players interviewing suspects and gathering clues, offering two methodically paced mysteries in one collection.
