The game uses the title screen image from the game Yggdra Union: We'll Never Fight Alone, but the gameplay is actually quite different. The title of the game in Chinese is 地下城塔防：黑暗联盟 (Dìxià chéng tǎ fáng: Hēi'àn liánméng) similar to the title of another game titled 地下城英雄：黑暗王朝 (Dìxià chéng yīngxióng: Hēi'àn wángchá /Dungeon Hero Dark Alliance).

A game with similar and identical gameplay was released on the iPhone platform in the same year. The game was titled “Princess of Fury” and was developed by a company called UltiZen Games and published by Mo-Star. It is not yet known whether UltiZen and Chuangshi Jiayou are the same company or interconnected because they are from different regions, Chuangshi Jiayou is from Beijing while UltiZen is from Shanghai.
