The plot of Gun Hazard revolves around a Bergen Army soldier named Albert Grabner. In January 2064, Ark Hellbrand of the Bergen Army stages a coup d'état in an attempt to overthrow the government led by President Moss Orwen. As the coup d'état forces begin to take over the country, President Orwen radios for assistance from NORAD and a faction of the Bergen Army loyal to him. Albert Grabner is sent to act as the president's bodyguard and helps him escape the country. However, the two are eventually captured by Hellbrand. Albert escapes from prison with the help of Brenda Lockheart, a mercenary employed by the Kernelight Association. Upon escaping Bergen and reaching New York City, they visit the Kernelight Association headquarters. Hoping to return to Bergen and rescue Orwen, Albert agrees to working for the Kernelight Association to find allies that can help him overthrow Ark. As the two work for the mercenary guild and travel to war-torn countries around the world, Albert begins to see a link between the civil conflicts, the Bergen coup d'état, and an organization only known as "The Society".
