Sure, it sounds dull but the rhythm and visuals (which were amazing before) helped create a beloved gaming experience that should only get better with Rez HD's updated visuals. The complete game, available on Wednesday, January 30 at 9am GMT / 1am PT, features five levels and three modes for various skillsets. Rez HD is rated E for Everyone by the ESRB and will cost 800 points on Xbox Live Marketplace.
