Wacca is Marvelous's first arcade rhythm game developed in collaboration with the independent Japanese record label HARDCORE TANO*C, known for their contributions to other rhythm games like beatmania IIDX and Sound Voltex. Gameplay can be thought of an amalgamation of the touchbar of Chunithm and the circular playfield of Maimai. The game is networked to SEGA.NET/aime for profile saving and content updates.
