Castlevania: Harmony of Despair which has been rumored for a while is officially coming to Xbox Live Arcade as part of the Summer of Arcade. The game is co-op in the story mode, although the number of players wasn’t announced. I’m sure Konami is saving that info for their press conference on Wednesday. The game also has a Survival mode(read: Horde mode)which lets players prove who is the best vampire hunter. Summer of Arcade begins in July, so expect it then.
