Things are going perfect for Doctor William Birkin, Chief of Viral Weapons Research at the Umbrella Corporation... until he plans to leave the company and work exclusively for the United States Government. Now, after years of research, he has created the ultimate viral weapon: the G-Virus. With the G-Virus, he can throw his plans into motion. But Ozwell E. Spencer, the head of Umbrella, has other ideas. Now agent HUNK of the Umbrella Special Forces and his elite unit of soldiers must infiltrate Doctor Birkin’s research facility and recover the G-Virus at all costs. They are the best at what they do...but little do they know what horrors await them in the cold concrete walls of the underground lab...
