We colonized seven hundred planets. Humankind enjoyed the benefits of expansion and the end of wars. We disbanded our military.

Then the Krall found us.

The Krall have used thousands of years of combat to select the genes of the strongest and fastest warriors. They are a species determined to dominate the galaxy, through annihilation or enslavement of every opponent.

Koban is an uninhabited high gravity planet with impossibly fast savage animals, which employ organic superconducting nerves. This deadly world is where the Krall are testing humans for fighting capability. We are useful only if we can fight well. If not, they will destroy us swiftly, as they have other species. They have slaves, and we’re poor tasting meat animals, so we fight or die. The Krall will use us, if worthy, seeking physical perfection through attrition of war, one planet at a time.

Growing weary of our failures in testing, the ruthless Krall are on the verge of a decision to eliminate our species. A ship carrying bio-scientists is captured for combat testing. The choice for Captain Mirikami and the scientists is simple: Prove we can produce better, smarter fighters quickly, or humanity is doomed to rapid extermination.

But the Krall are only half the problem. We must survive Koban's gravity and superfast animals. The tiger-like rippers with skin contact telepathy are predators too fast and powerful for the Krall to face. Our solution is genetic: If you can't beat them as you are, become human rippers.

The Krall will learn another species can bypass natural selection.
