Sgt. Greg Campbell is the sole surviving S.W.A.T. member of what he calls "The 5th Street Massacre" which took the lives of all his teammates. He is met by the Umbrella Secret Services atop a billboard with large lights on each side of him and a Denel NTW-20 Sniper Rifle, though it's not a typical S.W.A.T. Sniper rifle. He appears as a clinically insane man, overly determined to continue the orders given to "Kill Anything In Sight, Stay Alive At All Costs". Although, he doesn't seem to realize that this is a riot and in fact, a zombie outbreak.
