After Leviathan has been deactivated, the surviving members of Cerberus have decided to stay, rebuild and regain control. Create peace and find a cure. With their efforts, they stumbled upon evidence that the scientist that created the virus was a commissioned mercenary who could still be local to the site. Cerberus puts a plan into motion. Obtain scientist. Create cure. Capture the infected and survivors. Test incubation period. Test cure. End virus and regain control over the hysterical population.  As Cerberus advances in their mission to find the scientist, inner turmoil errupts. Finding that some feel there is no cure but a vaccine and the only way to salvation is to eradicate the infected to prevent the spread and must also create a police state in order to control the civilian violence.  After a small conflict, Cerberus has now found themselves bisbanded with half believing in the mission and the other half trusting the concept of a eradication of the infected. They create their own faction, Hel.   Reports of a secret agency made up spec ops, wet works, intelligence, doctors and demolitions experts called "S.C.P.", have been spotted around the area. S.C.P. are known for their aggression, violence and destruction leaving only ruins in their wake. Both Cerberus and Hel know that S.C.P can be a vital tool to their cause...for the right price. However, to get in their way would be paid with the highest price... Your life.  Hel must stop Cerberus from spreading the virus. Cerberus must stop Hel from killing the people they are trying to save. Both have a common interest... find the scientist. And they realize, the only way to do this is with the help of S.C.P.  And both know, the night is the approaching... the infected will wake
