A planet 8.6 light years from Earth, Alpha Centauri 3 was originally settled by human colonists for the purpose of mining the rich ore deposits and shipping them back to the resource-depleted Earth. Around the date 2593 A.D. a Predator drone ship placed Alien eggs onto the planet, which hatched and produced a fine crop of Alien prey. The human population was eradicated in the process. A Predator hunting party then arrived to hunt the Aliens, but the number of aliens was underestimated and all the Predators were, in turn, wiped out.
