Castlevania: Rondo of Blood, known in Japan as Akumaj? Dracula X: Chi no Rondo is a platform video game developed by Konami for the PC Engine. The tenth installment of the Castlevania video game series and a 2D side-scroller, it acts as a middleground between the earlier, typically linear Castlevania games and the later open-exploration ones; Rondo of Blood makes use of untimed stages with a clear beginning, but occasionally more than one ending. It was released in Japan on October 29, 1993. A direct sequel to it, the critically acclaimed Castlevania: Symphony of the Night, was released in 1997. Taking place in 1792, Rondo of Blood is set in the fictional universe of the Castlevania series. The premise of the series is the eternal conflict between the vampire hunters of the Belmont clan and the immortal vampire Dracula. Rondo of Blood centers on Richter Belmont, who searches for his beloved Annette after Dracula's servant abducts her. In Dracula's castle, he frees young Maria Renard, who then becomes a playable character, and two other maidens before finding Annette and defeating him. Castlevania: Dracula X, a game based on it but with a different art style, redesigned levels and altered gameplay, was released internationally for the Super Nintendo Entertainment System two years later. In 2007 and 2008, Rondo of Blood saw a first North American, European and Australian release and 2.5D remake as part of Castlevania: The Dracula X Chronicles for PlayStation Portable. The original PC Engine version became available in Japan in 2008 on Wii's Virtual Console and as an imported title, in Australia, Europe and North America in March 2010. Dracula X received mixed reviews while The Dracula X Chronicles was praised for its updated graphics and inclusion of bonus content such as a port of Symphony of the Night.
