Arrange was released online, featuring alterations to the GPS and gameplay mechanics, among other changes. Campaign Version DoDonPachi received a remixed arcade edition dubbed DoDonPachi Campaign Version, which was handed out as a first-place prize on a contest hosted by Cave to promote the Sega Saturn conversion, where each participant was asked to submit their highest possible score within a three-day period of the event. This limited edition is also referred as DoDonPachi Special Version and DoDonPachi Blue due to its title screen. Campaign Version runs on a different arcade hardware and is essentially the same game as the original DoDonPachi but with an extreme increase in difficulty and bullets on-screen, featuring a primitive incarnation of the "Hyper Mode" mechanic that would later be seen in DoDonPachi DaiOuJou, among other gameplay alterations. Only one DoDonPachi Campaign Version-branded PCB is confirmed to exist under ownership of contest winner "ZBL-NAI", although it is rumored that a total of 100 units were manufactured and some are speculated to be owned by other contest participants, while one unit was reportedly present at the "Daytona III" arcade center at Tokyo. Campaign Version made a brief appearance at the first "Cave Matsuri" festival held at the "HEY!" arcade center at Akihabara in December 2006, where two PCBs were available for attendees to play. In a 2010 press conference, former Cave producer Makoto Asada claimed that no additional boards were produced and the company lost its source code, effectively exposing Campaign Version to the risk of being lost forever in case of hardware malfunction. In a 2018 interview, Analogue CEO Christopher Taber stated that he pitched the idea of licensing a limited run of DoDonPachi Campaign Version arcade boards to Cave, which never came to fruition due to the necessary components for manufacturing PCBs no longer being production and Cave did not have spare units either. Reception and legacy DoDonPachi was generally well received by critics since its arcade debut and later on other platforms. Readers of the Japanese Sega Saturn Magazine voted to give the Saturn port a 8.9766 out of 10 score, ranking at the number 83 spot, indicating a large popular following. The game was included in the 2010 book 1001 Video Games You Must Play Before You Die. In a 2013 interview with Retro Gamer, programmer Steve Redmond stated that the title served as inspiration for his 2013 Xbox Live Indie shoot 'em
