Twenty years. That's an awful long time for a videogame series to lie dormant. Since it appeared in arcades in 1987, and in fuller form on the NES in 1988, Capcom has resolutely ignored its arcade platformer (besides allowing Nintendo to make a Game Boy Color version of sorts, called Elite Forces, in '99).
"But we enjoy swinging around on an extendable bionic arm shooting thinly disguised Nazis in a roughly satirical manner," bleated a legion (well, a gaggle) of fans. "It sold terribly here in Japan. Nobody cares. You're mad," retorted a gruff Capcom management. And that, for two long decades, was that.
