The Raiden series is a venerable one in the world of video games, albeit one that is not quite as prolific as some series of similar age.
Originally appearing in arcades in 1990, the original Raiden followed the mould of vertically scrolling shoot ’em ups that had been established some eight years previously by Namco’s Xevious and later expanded on by other classics such as Capcom’s 1942 (1984), Nichibutsu’s Terra Cresta (1985) and Konami’s Twinbee (1985).
Raiden didn’t reinvent the wheel, in other words, and it could be argued that its subsequent installments haven’t, either — but the series remains nonetheless a distinctive, noteworthy entry in gaming history, with second-to-latest installment Raiden IV: Overkill being one of the best, most satisfying yet.
