Who is Dr. Xenos, and why is his identity a closely guarded secret? The answer is as mysterious as the person himself. Living in the Rocky Mountains, Dr. Xenos has often seen the Bear Creek Air Force Base located a few mountains over from him, but he never thought he would get to see it firsthand. A very secret base, it was only accessible by air. However, Dr. Xenos's life and the mission of the base were linked. They had a common destiny and a common mission.

Dr. Xenos didn't know this until some visitors paid him a call. On that day, Dr. Xenos's life changed. His mission in life changed. At stake were the earth and its people. Dr. Xenos and his comrades would need all their training and skills to survive this challenge.

Their first goal was to save what they could of America. A goal all shared.
