Bashi Bazook: Morphoid Masher

Bashi Bazook: Morphoid Masher is a cancelled US release of Bio-Senshi Dan: Increaser to no Tatakai (バイオ戦士ダン インクリーザーとの戦い, translated as Bio-Warrior Dan: The Increaser Battle), an action game for Family Computer released by Jaleco. It is said that the reason this game was cancelled for release in the US was to avoid similarities with Xexyz, which was released by Hudson Soft at the same time. Later, a prototype ROM was leaked and then released, and now you can play!
