Contra

Contra is a seminal run-and-gun shooter developed by Konami for the NES in 1988. Set in 2633 AD, players control elite commandos Bill Rizer and Lance Bean as they battle the Red Falcon alien organization across eight stages of intense side-scrolling action. Known for its punishing difficulty, the game popularized the 30-life 'Konami Code' and set the standard for cooperative arcade-style gameplay on home consoles.
