The DonPachi series (also known as the DoDonPachi series, after the second game) is a series of Shoot Em Ups by CAVE. It is by far one of Cave's most iconic game franchises, with DoDonPachi being one of the earliest Bullet Hell titles. At first glance, it appears to be yet another game about flying a ship and blasting alien/robotic invaders, but many dark secrets lie beneath the surface. Art design for the first three games is done by "Joker" Junya Inoue. The series spans seven games: Compare Mushihime-sama, one of Cave's other big Bullet Hell series.
