Bloodstained: Ritual of the Night follows Miriam, an orphan afflicted by an alchemist’s curse that gradually crystallizes her body. To save herself and humanity, she fights through a demon-infested castle summoned by her former friend Gebel, whose body and mind have also been overtaken by crystal. Its gothic dark-fantasy story gives the castle’s exploration a personal stake.
Play centers on side-scrolling action RPG combat and exploration, drawing on Metroidvania design. Miriam can wield and upgrade weapons and spells, level them up, and customize their appearance. The game presents its environments in 2.5D, using 3D models within a 2D setting, while story scenes and conversations with non-player characters are fully voiced. These systems make progression, combat choices, and the castle’s interconnected exploration central to the experience.
The listed play format includes single-player as well as multiplayer options, including co-op and PvP, with online and shared-screen variants. The description additionally names Speed Run and Boss Rush modes, offering distinct formats alongside the story-focused journey.
