The year is 2215.

Humanity has expanded across the Solar System, building great cities on Mars while the terraforming of Venus is underway. But this new era of exploration is interrupted when an alien civilization launches a massive invasion from the outer reaches of the Solar System.

As the war escalates, humanity discovers that the invading forces are made entirely of robotic armies. Scientists study captured alien technology and begin developing robotic spacecraft of their own, incorporating alien technology in a desperate attempt to close the technological gap.

Despite these efforts, defeat becomes increasingly inevitable. The aliens deploy specialized equipment capable of disrupting control over Earth's robotic fleet, leaving humanity with one final hope.

Professor Likhtenshtarts develops a cybernetic intelligence module capable of copying human consciousness into an autonomous combat robot. The consciousness of Sergeant Gregor Golovkoff, one of humanity's most skilled soldiers, is transferred into the prototype robot spacecraft.

The secret mission begins as the newly created robot soldier is deployed to an alien space base near one of Saturn's moons, where the enemy's main forces are concentrated.
