Cygames, Inc. and DeNA Co., Ltd. have announced today that the iOS version of Cygames’ popular social card battle game Rage of Bahamut provided on DeNA Group’s Mobage network, has achieved the number-one ranking on the App Store’s Top Grossing chart in the U.S. The Android version of the title has also ranked number one on Google Play’s top grossing chart for more than six consecutive weeks in the U.S., making the title a cross-platform blockbuster.

Rage of Bahamut, developed originally as a browser-based title by Cygames and offered on DeNA’s Mobage network in Japan as Shingeki-No-Bahamut, is a fantasy adventure game in which players roam the world by collecting, synthesizing and evolving a variety of unique cards with intricate, fantasy-themed artwork. The title was recently localized into English and released in February as an Android app for Mobage’s worldwide network, operated by DeNA’s U.S. subsidiary ngmoco, LLC. The iOS version of the title was released on May 15 on Mobage as well, and has been steadily climbing the App Store’s top grossing chart. In addition to the access to Mobage’s user network, ngmoco has provided user-acquisition support for the title. Rage of Bahamut currently has more than one million registered users across Android and iOS.
