Circle of the Moon is the first of the GBA Castlevania games which follow the Metroidvania formula established and popularized in SOTN. Taking place in 1830, Morris Baldwin leads his son Hugh and student Nathan Graves to Castlevania to stop Camilla from reviving Dracula earlier than expected. Morris is captured and Hugh and Nathan are forced to find their way through the castle to fight Dracula. You take the role of Nathan, who carries a whip that can also be spun around and used as a shield against projectiles and kill weaker enemies. Dracula’s castle holds many secrets in its various areas and you need to use all the skills you have to find your way. The DSS cards you find from enemy drops give you different offensive and defensive abilities when used together. Each of the action cards is based on someone from Roman mythology, while the attribute cards take from Greek and Roman names. This castle holds different areas than what other Castlevanias have, including a Battle Arena. This game was eventually taken out of the main Castlevania continuity.
