Year 2078: They have come. Strange beings made of shadow. Killing everything in their path. It seems as though we are doomed. They are impervious to any and all earthly weapons. Year 2079: The world has put aside its differences to fight them off together. With the greatest minds on the planet working as one-it seems the discovery of a usable weapon is upon us. Year 2080: Zilla is born in what would be known only as "The Decade of the Shadow Walkers". Year 3002: Is where our story begins.
