Castlevania: Aria of Sorrow is a 2003 action role-playing game developed and published by Konami. It is the third Castlevania game for the Game Boy Advance. Producer Koji Igarashi, who had led the production teams for previous Castlevania games, led Aria of Sorrows development as well. Michiru Yamane returned to compose the music alongside Takashi Yoshida and Soshiro Hokkai. Director Junichi Murakami was new to the Castlevania series. Aria of Sorrow is set in the year 2035, when Dracula has been sealed away after a battle in 1999. The plot follows the journey of Soma Cruz, a teenager granted occult power as a result of being a potential vessel of Dracula's reincarnation, as he battles dark figures that wish to inherit the undead lord's power. The game incorporates the same combination of elements from platform games and role-playing video games as in a previous game Castlevania: Symphony of the Night (1997). Aria of Sorrow introduces several features to the series, such as the "Tactical Soul" system and employs a futuristic storyline in contrast to the medieval setting of other Castlevania games. Aria of Sorrow was released in May 2003. Although it sold poorly in Japan, selling 27,000 units nearly one month after its release, it was commercially successful in the United States, with more than 158,000 units sold in the three months following its release. Aria of Sorrow received universal acclaim, with praise for its visuals, gameplay (particularly the Tactical Soul System), music, and level design. Some critics considered it the best Castlevania game since Symphony of the Night. Konami released a sequel, Castlevania: Dawn of Sorrow, in August 2005. It incorporated many elements from its predecessor, including the "Tactical Soul" system. Aria of Sorrow was rereleased as part of the Castlevania Advance Collection on September 23, 2021 for the Nintendo Switch, PlayStation 4, Xbox One, and Windows alongside Castlevania: Circle of the Moon (2001), Castlevania: Harmony of Dissonance (2002), and Castlevania: Dracula X (1995). Gameplay Aria of Sorrow features a 2D side-scrolling style of gameplay where the player controls the onscreen character from a third-person perspective to interact with people, objects, and enemies. Like previous games in the series and most role-playing video games, characters level up each time they earn a set number of experience points from defeating enemies; each "level" gained increases the character's statistics, thus improving their performance in battle. Statistic examples include hit points, the
