DonPachi

is a 1995 vertical-scrolling bullet hell arcade game developed by Cave and published by Atlus in Japan. Players assume the role of a recruit selected to take part in a secret military program by assaulting enemy strongholds in order to become a member of the "DonPachi Squadron".

DonPachi was conceived as a project that evoked the same spirit from shoot 'em ups created by Toaplan, a request Atlus wanted as publisher though conflict emerged as to how close the game should be to Toaplan shooters while members at Cave pointed out elements uncharacteristic from Toaplan during development. Although first launched for arcades on Cave's first-generation hardware, the title was later ported to Sega Saturn and PlayStation, each featuring several changes and additions compared to the original version. The PlayStation version has since been re-released through the PlayStation Network download service.
