A job posting on a Japanese developer's site has hinted that Square Enix will be releasing a brand new RPG on the iPhone sometime later this year. Media.Vision has posted that they're seeking to fill a number of positions related to building an RPG on Apple's platform in conjunction with Square Enix. The Final Fantasy Ring fansite says that the game will be called Chaos Ring, and will by produced by the same team that made the popular Wild Arms console series.
FFRing also says (via Japanese translation) that the game will be a 3D title, and it will feature a storyline concerning five pairs of warriors who fight to the death for the right to eternal youth. Each game stage will consist of a ring of battles with a boss in the center, and some choice in how the player takes on enemies -- more challenge for more risk.
It sounds intriguing. Square Enix has been seeing some success with its older titles on the iPhone, and we know it's got a few original titles already in the pipeline for Apple's platforms. It'll be great to see what they can cook up for the App Store.
