Fun Fact: The famous Konami code only granted 10 extra lives instead of 30 as in the original Contra, and it only worked once in Super C.
Super Contra was an arcade sequel to the coin-op Contra. It was ported to the NES as Super C, another “impossibly hard” NES game. Playing this game with a friend is strongly advised.
The 3rd person corridor sequences from Contra were replaced with top-down vertical-scrolling levels. The NES port of Super C had three unique levels not featured in the arcade version, and the flamethrower-type power up weapon was adjusted to be more devastating in the sequel.
Super C was otherwise more of the same, but that was okay because “the same” in this case was Contra, one of the most popular games on the NES.
