Nick

Nick is one of the four playable Survivors in Left 4 Dead 2, voiced by Hugh Dillon. He's a gambler and a conman in a slick, expensive suit. He is also very cynical, so he takes the role of '"the complainer" of the Group. Nick joined the other three in their quest to find salvation but is unsure about whether or not he can trust them, often comparing them to The Three Stooges. Still trying to figure out the best "angle" to get from the recent zombie apocalypse, as the time goes by, he starts to value his Survivor compatriots.

Official Description
Georgia was just another stop on this drifter's journey—certainly better than his time in the joint. Sensing easy money on riverboat casinos, Nick reeled in as many fish as he could at the poker tables. He didn't expect to spend the rest of his life in Savannah, but in the zombie apocalypse, how long will that really be?
