Gears of War kicked off a memorable trilogy with a plot that surrounded Emergence Day, the day the warlike Locust race arose from the bowels of Sera, turning their attention to wiping out humanity from the face of the planet. The Coalition of Ordered Governments summoned their best soldiers, the COGs, to combat the threat, and Gears of War explodes into an all-out war against those who seek to reclaim Sera for their own -- namely, the Locust Queen.
