The Taiwan Digital Game Rating Committee has rated Castlevania Advance Collection for PlayStation 4, Xbox One, Switch, and PC.
The unannounced collection was first rated in Australia on June 18, then again in Korea on June 25.
The collection will presumably include the three Castlevania games released for Game Boy Advance from 2001 to 2003: Castlevania: Circle of the Moon in 2001, Castlevania: Harmony of Dissonance in 2002, and Castlevania: Aria of Sorrow in 2003.
Another rating for the unannounced collection appears.
