The earliest build of Capcom’s Resident Evil 4 was designed and intended for the PlayStation 2 under RE2 director Hideki Kimiya’s wing. RE4 would suffer a few more scraped incarnations before the finalized product hit Nintendo’s Gamecube (before finally being ported to the PlayStation 2…and then everything else in existence after that).
Unlike those versions, however, the first working build was salvaged and reconfigured into Devil May Cry. DMC ended up spawning three sequels, a manga, an anime, and is awaiting a reboot by Enslaved dev, Ninja Theory, as well as an upcoming feature length film.
