Mirror 2: Project X frames its adventure around parallel worlds, a cast of supernatural characters and choices that influence the story. Its cel-shaded presentation is described alongside an Unreal Engine 4 foundation, giving the game a stylized setting for tales that range from vampire folklore to post-apocalyptic wandering.
In Story Mode, decisions can affect match-3 battles, where matching at least three gems of the same kind earns points. Challenge Mode offers another route through the game, while Home Mode shifts the mood to a relaxed holiday on Dodai Island. There, players can photograph characters in different locations, adjust poses and explore clothing and accessories; the mode also lists Steam Workshop support.
That combination of narrative choices, gem-matching and character-focused scenes makes Mirror 2: Project X a distinctly single-player experience rather than a game organized around competing player populations.
