Quartet (Rev A, 8751 315-5194)

Team up with up to three friends in Sega’s Quartet, a fast-paced action game released in 1986 that blends platforming and shooting elements. Players choose from one of four characters – Joe, Mary, Lee, or Edgar – each distinguished by their color and embark on a mission to reclaim an Earth colony satellite station overrun by robots. Levels alternate between straightforward platform sections requiring careful navigation and sequences where players can acquire jetpacks for aerial combat. The core gameplay involves traversing these environments, destroying waves of robotic enemies and ultimately confronting a unique boss at the end of each stage. Defeating a boss unlocks a key that allows progression to the next level. Throughout your journey, power-ups are available to enhance character abilities and weaponry, aiding in the fight against the mechanical invaders. Quartet's simultaneous four-player action creates a chaotic and engaging experience reminiscent of other cooperative shooters from the era. Built on Sega's System 16A hardware, this title offers a challenging and replayable arcade adventure for groups seeking coordinated teamwork and intense shoot-'em-up thrills.
