Developer Treasure has brought co-op fans some great games through the years: Gunstar Heroes, Radiant Silvergun, and Ikaruga immediately come to mind. These three Treasure titles, among others, have been (or soon will be) released for Xbox Live Arcade, and this fall another joins the ranks. Guardian Heroes is getting the full HD remake treatment, with all new graphics and a widescreen presentation. Online co-op, as well as standard couch co-op, will be included, too. I've heard lots about this storied action-RPG hybrid, but never played it since it was only released on Sega Saturn. We look forward to hearing more about Guardian Heroes as its fall release date draws closer.
