Battle Moon Wars

Battle Moon Wars is a PC-made series of Super deformed Tactical RPG games created by Dojin soft developer and publisher Werk in 2005. Its popularity in Japan has given rise to a number of Battle Moon Wars games. The series has a basic similarity to the Super Robot Wars series and its Super deformed looks, as well as taking its crossover concept, though it has overshadowed Battle Moon Wars due to its huge fanbase in Japan and in other nations, as well as its presence in the Japanese video game market for some time.

The game uses the crossover of Type-Moon's visual novel and anime series, including Tsukihime and Fate/stay night with several original characters made exclusive by Werk. Their involvement in the series are covered as Acts.
