Early in the 21st Century, THE TYRELL CORPORATION advanced Robot evolution into the NEXUS phase -- a being virtually identical to a human -- known as a replicant. The NEXUS 6 Replicants were superior in strength and agility, and at least equal in intelligence, to the genetic engineers who created them. Replicants were used Off-world as slave labor, in the hazardous exploration and colonization of other planets. After a bloody mutiny by a NEXUS 6 combat team in an Off-world colony, Replicants were declared illegal on earth -- under penalty of death. Special police squads -- BLADE RUNNER UNITS -- had orders to shoot to kill, upon detection, any trespassing Replicants. This was not called execution. It was called retirement.
