Intro. Your Star System was ravaged by a pathogen capable of transforming anything organic and alive it touched The Government and the Military worked desperate to push it back but they can not fully win. Operations after operations, humans were only capable of stalling and retreating, rarely advancing. Rescuing, Evacuating and Vaccinating humans, Containing the outbreak, Eradicating the infecteds were all their top priorities. You are one of the fortunate few survivors who survived the outbreak in your home city in planet Montana, but unfortunate enough to miss the government planetary evacuations. You move city to city to try and make it into another evacuation that is made by a group of volunteers trying to gather as much survivors as possible.
