Meet the Left 4 Dead 2 Survivors

Left 4 Dead 2 is set in the south, a journey from Savannah Georgia to New Orleans Louisiana. With the new game setting we are introduced to a new set of survivors. Valve is trying to open up the L4D world and impart to players that this infection thing is big. So while Francis, Zoey, Bill, and Louis are doing battle in Philadelphia; these four are fighting the infected in the southern swamplands…
Nick

Lured by fast money and river boat gambling, con man Nick made a stop in Georgia. There’s always another con just a little further down the road, Nick never intended to make Savannah his final stop. Then again the Zombie apocalypse wasn’t part of his plan either.
Hugh Dillon of Flashpoint plays Nick.
Rochelle

Producer for a cable news network, Rochelle was sent into Savannah to cover what would turn out to be the outbreak. Rochelle finds herself right in the middle of the chaos, not being one to let live slip away she grabs a gun and meets the infection head on.
Rochelle Aytes of White Chicks plays Rochelle.
Coach

After a knee injury ended his athletic dreams, this ex-defensive lineman turned to teaching. Coach is now pushing 40 and wishing he’d taken better care of that knee, but who knew that one day he would have to run for his life in the face of the ever growing zombie hoard? Coach has developed an extreme hatred of the Zombies, the Witch in particular.
Chad L. Coleman of Terminator: The Sarah Connor Chronicles plays Coach.
Ellis

Brash, cocky, and indestructible. This 21 year old mechanic and Savannah native isn’t scarred of some infection. Ellis enthusiastically replaces his Miller High Life with a gun and heads out into the fray.
Eric Ladin of Generation Kill plays Ellis.
