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.
Game Overview
Alien Syndrome is one of those NES ports that somehow feels both frantic and clunky at the same time—in a weirdly charming way. You and a buddy blast through maze-like spaceships, rescuing hostages while swarms of aliens crawl out of the walls. The overhead view makes it hard to tell what’s a wall and what’s just background art, so you’ll probably waste a few shots before getting the hang of it.
The arcade original had smoother controls, but there’s something oddly satisfying about the NES version’s janky movement. Just don’t expect precision—your character slides around like they’re wearing socks on a spaceship floor. The aliens? They’re mostly just blobs with teeth, but they come at you fast. Bring a friend if you can—it’s way more fun when you’re both yelling at the screen.
