For as the myth that shrouds the planet's secret rulers is exposed by a handful of scientists and warriors dedicated to freeing humanity from the eternal yoke of slavery, the truth becomes more deadly... ZERO HOUR Deep inside the moon, a dark and timeless place of unimaginable power and mystery, two ancient beings live on - the sole survivors of two mighty races whose battle to rule earth and mankind is poised to end after millennia of struggle and subterfuge.
