Daniel Callahan

 Daniel Callahan grew up as a typical child would just outside Manhattan in the Bloomfield area. He spent most of his time playing with plastic army men inside his bedroom and played an excessive amount of video games. He was fortunate enough to even keep active lifestyle at his age when his mother and father stepped in and got him focusing more on his grades and staying actively fit. He grew out of video games and took up an interest in becoming a doctor during his college years.

His father’s life was taken during the shocking events that transpired during September the 11th in 2001 with the World Trade Center. This changed Callahan’s outlook completely and he felt compelled to serve in the U.S. Army when the Iraq and Afghanistan war broke out.

He completed two tours in Iraq and one in Afghanistan. He was promoted to Staff Sergeant in his last tour of duty for his excellent performance on the field. With several tours of duty under his belt, Callahan was honorably discharged after receiving serious injuries from his last tour. He settled down in the city of Oceanside, Florida. There he married his wife Jeannette Callahan.

However, as the ZA1 virus swept through Europe, the U.S. government established an entirely new division aimed at repelling the infection. Callahan became one of thousands of individuals to be picked to serve in this new division and he was then forced to leave.

The European ZA1 conflict
With the ZA1 pathogen outbreak sweeping across the European continent, The United States felt compelled to establish a new division specifically trained for the combat against ZA1 carriers. The threat in the European theater from the ZA1 pathogen greatly increased as Germany fell to the infection. Eventually, France would be next as incredibly massive hordes of infected carriers swept through the European countryside.
