Castlevania Double Pack collects two great Castlevania titles for the Game Boy Advance. The set provides twice the incredible gothic adventure for one low price! In Castlevania: Harmony of Dissonance, you'll use your new "Spell Fusion" powers to acquire the relics of Dracula, left behind from 50 years in the past, to unravel the disappearance of your friend Lydie. In Castlevania: Aria Of Sorrow, you'll take on murderous monsters and absorb their souls to gain their abilities--and uncover a terrible secret.
