Play Alien Syndrome (Japan) Online Free

Alien Syndrome is a faithful Famicom port of Sega's iconic 1987 top-down run-and-gun arcade game. Players control Ricky or Mary, agents sent to rescue crew members from spaceships infested by grotesque alien organisms. Each level features a ticking time bomb, adding a layer of urgency as you hunt for survivors. Once enough crew members are rescued, you must face a massive, screen-filling alien boss. The game features a variety of power-ups, including lasers and flamethrowers, to help manage the alien swarms. Alien Syndrome is a high-octane classic that combines sci-fi horror with fast-paced arcade shooting.
