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. Replicants were used Off-world as slave labor. Those who escaped to Earth where hunted by Blade Runner units ordered to kill any trespassing Replicant upon detection. A rise in the manufacture of bootleg Replicants in the Far East has forced The Tyrell Corp to engage in a costly patent war to ruthlessly protect its unique Intellectual Property. Corporate agents and Blade Runners have been dispatched to pursue any copyright infringement by the industrial pirates with extreme prejudice in order to protect and preserve Tyrell's monopoly.
