Though you may not know it by title alone, because Konami have elected to drop “Contra” from the title all together, giving it an identity that will click with a niche audience while perhaps opening itself up to a new one with no prior affection for the series. Those of you that fall into that smaller audience might remember where the Hard Corps moniker comes from. That would be Contra: Hard Corps, originally released in 1994 on Sega Genesis.
While it was similar on a surface level to the Contra entries that came before it, Hard Corps always felt more like a Treasure-developed game, with an emphasis on multiple paths, wacky/wild boss encounters, and a very strange sense of humor. Hard Corps: Uprising takes it into sequel territory, putting the player in the shoes of Colonel Bahamut, the first game’s primary antagonist.
