About this game

Iridion II Overview

More than a hundred years have passed since the Earth was attacked by the vicious IRIDION forces. Legend tells of a single brave SHN Fighter pilot who found his way to destroy the evil IRIDION mainframe. After this glorious victory, all remaining enemy ships disappeared from known space. Humans began to colonize the planet systems of the IRIDION home galaxy. Peace and freedom came back to mankind. The IRIDION menace was history.

Until now.

Within only one day, all communication with the human space outposts had been lost. The last transmissions made it clear that the IRIDION Empire had returned and have taken over all colonized systems. Planet Earth is too far away to send help in time. Again only a single, but powerfully equipped spaceship is within reach to stop the IRIDION forces before they can go on to attack the last remaining planet of human beings… Earth.
