Play Alien Syndrome (Japan) Online
Blast through cramped spaceship corridors with a buddy, sliding around like you're on ice while aliens pour out of the walls—half the challenge is figuring out what's actually a wall. It's messy, chaotic, and weirdly satisfying once you embrace the jank.
Alien Syndrome came out on the NES in 1987, published by Sega. It was part of that wave of arcade-style games ported to home consoles, where you got a direct, sometimes simplified, version of the coin-op experience. It didn't try to reinvent anything; it was just a solid, straightforward action game for its time.
You control a space marine navigating a maze-like starship infested with aliens, screen by screen. Your main goal is to rescue hostages scattered throughout each level before a timer runs out, all while fending off waves of creatures that spawn from the walls and floors. The signature mechanics include a multidirectional shot that lets you fire in eight directions and a screen-clearing smart bomb for emergencies. The pacing is relentless, and the difficulty is unforgiving, with enemies appearing from all sides in tight corridors. It feels like a constant, frantic scramble for survival where every rescued captive is a small victory.
