Locutus of Borg was the Borg designation forced upon Starfleet Captain Jean-Luc Picard after his assimilation in late 2366. The Borg intended to use Picard as an intermediary, a spokesman for the Human race in order to facilitate the assimilation of Earth so that the process would be as quick and as possible, with the fewest number of casualties on both sides.
The Borg Queen herself had been on board a Borg cube where Picard had undergone his transformation into Locutus. Interested in overseeing this event, she had intended for Picard to become her equal counterpart but, when he refused to give himself willingly and accept his assimilation, the Queen was forced to turn Locutus into merely a drone.
Fortunately, the crew of the USS Enterprise-D was able to capture Locutus and remove his implants and heal his wounds, however, Picard's assimilation continues to haunt him.
The Borg have travelled back in time to 2012
The Borg Queen and her drones have arrived on earth, with the single purpose of assimilating the entire human species. You will all become drones to serve the collective. You will be injected with nano probes and have cybernetic devices implanted in your eyes, ears and other organs and limbs!!
You must find all 3 humans who have become Borg and have escaped and been been severed from the collective, for only they know how to defeat the Borg Queen.
