The game features not just one story, but several and they’re called “cases.” They’re like a movie or a full season of a TV show. Each one of them features a standalone plot that reaches a conclusion. The first case in the game is Murder on the Orient Express, which is based on the famous mystery novel by the renowned author Agatha Christie. The cases are usually unlocked in sequence. For example, Case 01 must be completed before players can move on to Case 02. However, some special cases can be played at any time alongside the main ones.
