The sound of gunfire awakens retired Marine Corps Master Sergeant John M. Walker from his drunken stupor of the night's festivities. A flash back to some far off battlefield leaves him as he remembers where he is at. The Friendly City of Rock Ridge Virginia. The sound of screams ring out as he jumps from his bed, looking out in front of him he sees the burning cars and buildings with hordes of people attacking his neighbors. The look on the attackers face showed blood running from their eyes with bloody froth coming from their mouths. The Friendly City was now the City of The Infected. Master Sergeant Walker has a new mission, the mission is to save his family, to survive and find out who did this.
