Contra Advance: The Alien Wars EX (released as Contra Hard Spirits in Japan) is a localized version of the classic run-and-gun shooter for the Game Boy Advance (GBA). Reimagining 'Contra III' for the handheld, it removes the Mode 7 top-down levels of the SNES original and replaces them with side-scrolling stages from the Genesis game 'Contra: Hard Corps.' Players control Bill Rizer and Lance Bean, utilizing a locking arsenal system to battle alien forces. It is known for its intense difficulty and classic Konami code nostalgia.
