Planet Xonader has spent thousands of years supplying the galaxy's most destructive conflicts with its signature product: semi-conscious organic weapons called Thinking Weapons, which grant their wielders massive firepower and enhanced battlefield awareness simultaneously. When a Xonadian starship made an emergency crash landing on a remote planet called Earth, the weapons were ejected and scattered across the surface. A second ship has been dispatched — Captain Plasma and Crystal Soldier aboard — to recover the weapons and find out what happened to the original commander. What they find on Earth will shake everything they thought they knew.
