WHO ARE THE GRAYS?
The mysterious Grays have studied humanity for thousands of years. Earth's remote location in the backwaters of the galaxy made it an ideal location for the alien race to conduct research that is too dangerous to perform on any of their homeworlds. Embroiled in an interstellar war with an unknown enemy, the Grays's were desperate to develop a super weapon that would ensure their survival. The natural resources and large population of Earth, combined with the human leaderships' corrupt accommodation provide the perfect facility for the Grays biological warfare development.

In 1947, a Gray research ship experienced a major malfunction resulting in a crash near Roswell, New Mexico. The United States Government quickly covered up the truth, sealed off the site and recovered a badly wounded Gray named "Edgar" who was transported to Area 51 for stufy. In the time that followed, major elements of the government were co-opted by the powerful Illuminati, a secret organization of elitists dedicated to ruling the world from the shadows. The Illuminati used their influence to set a new secret agenda for Area 51. A major base was built over the initial laboratory that housed the cripped "Edgar," and the Grays established a research facility 3 miles below the desert surface. Since then, it has served as the only secure landing site for all subsequent Gray vessels.
In time, the Illuminati formed a pact with the Grays, granting them needed resources (including humans for experiments) in return for exclusive access to Gray technology.

For the last 20 years, human and Gray researchers have worked in tandem to great effect, creating a creature-weapon code-named "Theta" intended for use in the distant alien conflict. One human scientist, Dr. Winstron Cray, is working with the mysterious Edgar on perfecting a viral weapon. Cray believes mating this virus with the "Theta" project will yield the super-weapon the Grays have long sought.

Tipped off by Edgar, Dr. Cray now struggles to prevent the Grays from completing their weapon and destroying Earth. Since the Illuminati control the laboratories of Area 51, Cray risks everything by calling for help. He released his viral weapon within the subterranean sections of the base with the intention of creating chaos and distration within the Illuminati, hoping to stall completion of the Grays' plans and prompt interference from military forces on the surface. The resulting infection spread to the upper sections of the base and military commanders reacted quickly by sealing the area and calling in Military Hazardous Materials Teams. After the initial HazMat Team Delta went missing, a second unit was dispatched. HazMat Team Brazo must discover the fate of Team Delta and discover the source of the deadly virus.
