Celebrating 20 years of vampire hunting, Konami releases 2006's Castlevania Double Pack. The cartridge includes updated versions of 2002's Castlevania: Harmony of Dissonance and 2003's Castlevania: Aria of Sorrow. In Harmony of Dissonance, the RPG adventure begins as Juste Belmont, descendant of Simon Belmont, is informed his friend has been kidnapped. Play as Juste and crack the whip against Dracula's minions, or create a new arsenal by using the new Spell Fusion mode to combine weapons and magic. In Aria of Sorrow, you are Soma Cruz, a high school exchange student studying in Japan. After being knocked unconscious you awake in a strange castle. Use multiple weapons to defeat monsters and collect their souls. Souls are important in Aria of Sorrow as they increase your abilities. Two players may trade souls by using a link cable.
