Zillion

Zillion is a space adventure platform video game designed for the Sega Master System as a companion for the Zillion anime in 1987, both of which were named after the laser gun employed by the main characters. The gun was used as a design model for the Sega Master System Light Phaser. The game is a free-scrolling platform/adventure in the vein of Metroid. It also has objects to be inspected and the necessity of enabling functions by accessing codes in the vein of Impossible Mission. A sequel to the game, Zillion II: The Triformation was also released.

Zillion is a game where you play the role of one of three team members from a military force known as the White Knights. The mission is to retrieve the five floppy disks from the Norsa Forces base on Planet X, find the captured teammates, Apple and Champ, and destroy the Norsa base by entering a code in its mainframe. After being dropped off by Mother Ship and reaching the underground base, the rest of the game consists of moving from room to room through the Norsa facility.
