Play Zillion (Japan, Europe) (En,Ja) Online

Zillion came out for the Sega Master System in 1987, developed and published by Sega. It was one of those games that felt a bit different from the usual platformers or shooters on the system, leaning more into exploration and careful movement. The setting and mechanics gave it a distinct identity during the console's early years.

You control JJ, a member of the White Knights, infiltrating an alien base to rescue captured agents and destroy the complex. The game plays across interconnected rooms, with an emphasis on finding hidden passages, avoiding traps like laser grids, and using a limited-use laser pistol to defeat robots. Progression depends on collecting access cards (floppy disks) to open new areas, and the difficulty is unforgiving; one hit kills you, and precision jumps are essential. It feels tense and methodical, rewarding patience and observation over quick reflexes.
