Castlevania: Circle of the Moon

Castlevania: Circle of the Moon, titled Castlevania in PAL regions, is a 2001 action role-playing game developed and published by Konami for the Game Boy Advance handheld game console. The game was developed as a stand-alone title in the Castlevania series and as a launch title for the Game Boy Advance.

The game's plot follows a vampire hunter named Nathan Graves as he attempts to rescue his mentor from the clutches of Dracula. Following the Metroidvania style of gameplay established by Castlevania: Symphony of the Night, Circle of the Moon expands on the magic attack mechanics of the former with the Dual Set-Up System, which allows for attacks to be mixed and matched by players as they see fit.
