Undefined Fantastic Object elevates the story of the Touhou franchise to a whole new level of absurdity. UFOs are invading Gensokyo and Reimu and the girls ascend to investigate – and shooting game violence ensues. Putting narrative aside, Undefined Fantastic Object is a step up over the previous installments in the bullet hell shooter series. Touhou Hisoutensoku is an expansion to Scarlet Weather Rhapsody which introduces a few new characters, story modes, and giant catfish boss battles.
