Last December, asynchronous multiplayer strategy game Battle Dungeon hit the App Store. Less than a week after the game was released, an .ipa file surfaced on the internet and illicitly obtained copies of Battle Dungeon caused a huge amount of stress on the game's servers. The team behind Battle Dungeon, Hunted Cow, was forced to shut it down after the server load caused technical difficulties that the team did not have the resources to fix. Hunted Cow did not give up on Battle Dungeon and has today released a new version of the game in the App Store. Battle Dungeon: Risen is a redesigned single player version of Battle Dungeon that features a number of improvements.
