Earth in 2114: atmospheric instability and resource exhaustion have made the planet nearly uninhabitable. Nations colonize other planetary systems, and a compatible system draws multiple national groups simultaneously. Orderly colonial development collapses when an unidentified life-form attacks and destroys the 6th colony outright. Regular military forces are routed. The Governor General turns to mercenaries — former cargo-ship defenders, now genetically and cybernetically enhanced, equipped with weapons that outclass the standard military. What they are sent into is no longer a settlement. It is a battlefield where life and death have lost their ordinary definitions.
