Blizzard launched the beta test of Hearthstone: Heroes of Warcraft this week, even as it prepared to sue a copycat game running on iOS and Android being served to gamers in China.
According to MMO Culture, Blizzard and its partner in the region NetEase have filed a lawsuit in China's courts alleging that the iOS and Android game Legend of Crouching Dragon seems to have borrowed core elements from Hearthstone including its card designs, values and game mechanics.
Blizzard and NetEase are suing developer Unico for $1.65 million in damages and are seeking an injunction from the court to shut the game down. It is currently only available in China.
Blizzard has known about the game's existence since October.
