CardMon Hero (previously known as Orka Online, Yuina Online: Adventure ORKA and Camon Hero) is an anime-inspired free-to-play massively multiplayer online role-playing game (MMORPG) developed by Redbana and published by HanbitSoft. The game is unique in that players are able to command their primary avatar along with various mercenaries summoned via magical cards. Also, unlike most MMORPGs players, are not given classes to choose from but instead weapons which can be changed at any time and depending on which weapon is equipped decides what cards can be used. The game was released worldwide in Open Beta on January 19, 2011 and a full release has yet to be announced.
