About Earthion
Earthion is a side-scrolling space shooter developed by Ancient Corporation for 16-bit systems. You guide space fighter pilot Azusa Takanashi through eight levels, fighting alien invaders to save Earth. Each level has its own environment, enemies and boss fight.
Fight through the levels
You deploy an arsenal as you battle through the stages. After completing the game on Hotshot difficulty, you can take on Challenge mode and compete for a place on the online leaderboard.
Music and presentation
The soundtrack by Yuzo Koshiro contains 27 original tracks, alongside sound effects. The game was developed to run natively on 16-bit hardware, and its versions for modern platforms include customizable scanline configurations. These scanline options are not available in the Mega Drive/Genesis editions.
