Play Zillion (Japan, Europe) (En,Ja) Online
Sneak through an alien base as JJ, dodging laser grids and blasting robots while hunting floppy disks—just don’t trust the walls, half of them aren’t real. That laser pistol feels great, even when the janky jumps send you into a turret’s line of fire.

Game Overview
Zillion on the Sega Master System feels like Metroid's scrappy little cousin—same vibe of exploring a maze-like base, but with way more '80s anime flair. You play as JJ, this red-suited agent sneaking through an alien facility packed with laser grids, weird robots, and doors that only open if you punch in the right passcode (good luck remembering those).
The floppy disk hunt sounds simple, but the base is full of dead ends and hidden passages—I got lost for ages before realizing some walls are fake. And those energy bars drain fast when turrets pop out of nowhere. Still, blasting guards with the laser pistol never gets old, even if the jumping physics feel a bit stiff at first. It’s got that classic "one more try" pull when you barely miss a disk.
Fun detail: the manual actually matters here. Those passcodes? Yeah, they’re tucked away in the booklet like some retro DRM. You’ll either love the extra layer or hate digging for scraps of paper mid-game.
