Contra, which launched on the NES in 1988, sold much better than Gradius and is more closely associated with the Konami Code's origins. In it, cheat-code sharers discovered video gaming's Charm of Making -- up, up, down, down, left, right, left, right, B, A, start! -- and were blessed with 30 lives, absolutely critical to a super-tough one-hit-kill side-scroller like Contra. Nostalgia for the Konami Code, if not gratitude for its usefulness to many difficult games of the day, led to its inclusion in numerous other works. A Wikipedia entry on the code counts more than 100 Konami games with the cheat or some version of it inside them. Another 22 games made by other publishers included the code as a tribute, often revealing an Easter egg or secret message. It has also shown up elsewhere in popular culture, most recently in Google Stadia's website (and on its controller), and as a pastime Easter egg in Fortnite in October.
