The Gundemonium Collection consists of three titles: Gundemonium Recollection, GundeadliGne, and Hitogata Happa. Each game delivers action packed 2-D anime-style game play, and brings the intense indie ‘bullet hell’ genre to the PlayStation3 computer entertainment system. Each of the titles offers multiple levels of frenetic action and high–impact weaponry. All of the titles will offer PlayStationNetwork Trophies and remote play capability.

They are localized doujin, or Japanese-style indie video games.
