The online multiplayer Castlevania title, Harmony of Despair, is heading to XBLA on August 4th for the price 1200 MS points. Currently, the title is an Xbox 360 exclusive.
Castlevania: Harmony of Despair takes characters from past 2-D Castlevania adventure titles and throw them into an 6-player online environment with a variety of modes. The title still keeps the 2-D environments of the previous titles, but allows you to zoom out the camera to see multiple rooms at once, or the entire map, at once.
You can check out some of the E3 media after the jump.
