Trivia / Raiden

• Channel Hop: On July 2022, NIS America got the publishing rights of Raiden IV from H2 Interactive, resulting in Raiden IV: Overkill being delisted from digital platforms after the announcement of Raiden IV x MIKADO remix for PlayStation 4, PlayStation 5, Xbox One, Xbox Series X|S and PC. NIS America also acquired the publishing rights of III after announcing a western release of Raiden III x MIKADO remix, resulting in the Windows port being delisted.
• Keep Circulating the Tapes: Despite being one of the most iconic arcade shmups, Raiden II has not had a rerelease since 1997 with its Windows PC version, which is long out of print and became an Abandonware. However, in 2014, after well over a decade of dealing with encryption issues, the game was finally brought to a working state in the MAME arcade emulator. Similarly, the aforementioned Windows version can be found elsewhere in the internet.
  • Similarly, Viper Phase 1 has never seen any home ports nor are in any Compilation Re-release.
• No Export for You:
  • The Playstation port of DX was only released in Japan.
  • The Windows version of III was also this when it was released exclusively in Japan during 2006. However, with its original publisher CyberFront disbanded in December 2013 and later H2 Interactive salvaging it, the port got rereleased internationally through Steam service in 2014, EIGHT YEARS after its original release.
• Sleeper Hit: As revealed in this interview, the original game was a low-expectation project only made because the developer's previous game flopped and a vertical shmup was all they could do with the alloted budget. The game initially sold poorly, but eventually ended up being very successful thanks to positive word-of-mouth.
