Alex Kidd With Stella - The Lost Stars (c) 1986 Sega.

Alex Kidd: The Lost Stars features Alex Kidd and Stella (controlled by player 2) searching for the twelve Zodiac signs. Alex's mission is to run through each level, knocking down enemies, and obtain the six miracle balls. These balls are hidden inside such unusual places as golden eggs, the Fantasy Zone ship out of action, clamshells, Christmas presents, pumpkins, and desk bells. Levels include Toy World, Machine World, the World of Make Believe, Water World, and Monster World.


Runs on the Sega "System 16A" hardware.
Game ID: 317-0021

Players: 2
Control: 8-way joystick
Buttons: 2


Released in December 1986 in Japan.

This game is the debut of Sega's first mascot, Alex Kidd who mostly appeared in various games for the Sega Master System. Alex's only game that was made for the Sega Mega Drive was "Alex Kidd in the Enchanted Castle" in 1989. Alex Kidd's last game was titled "Alex Kidd in Shinobi World" which was somewhat of a crossover between the Alex Kidd series and Shinobi. In 1991, Alex Kidd was replaced with a 'faster than a speeding bullet'-type character called Sonic The Hedgehog.

Opa-Opa, the main character from "Fantasy Zone", appears as the container for the 'Miracle Ball' in round 2 of this game.

Sony Music Entertainment / Scitron released a limited-edition soundtrack album for this game (Sega Arcade 80's Vol.1 - SCDC-00245) on 19/02/2003.
