Rex was an ordinary salaryman, resigned to a dull life of monotony in a towering megacity. But his world shatters when he's conscripted by Nexum Dynamics, a ruthless megacorporation, and thrust into a brutal war for a barren, alien world.

The planet holds unimaginable riches, but it’s also swarming with the Krhyssari, an insectoid race that dominates the surface with their hive-mind precision and relentless aggression.

Amid the carnage, Rex had an extraordinary encounter with Cleo, an ancient AI, a survivor of a long-extinct civilization. Cleo isn't just an artificial intelligence; she’s a consciousness imbued with memories of her people's interstellar empire and equipped with advanced bio-nanotechnology.

Offering Rex a new purpose and unmatched power, she transforms his fragile human body into a hybrid of living metal and flesh, making him the ultimate weapon.

But Cleo is more than a tool of war. As she journeys alongside Rex, her cold, logical algorithms evolve, shaped by his humanity.

Together, they form a bond that transcends the boundaries of man and machine, discovering love in the midst of chaos. As Rex and Cleo fight for survival, they uncover a shared ambition, to rise as intergalactic overlords, uniting or conquering the galaxy.
