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, and so takes the Louis role as the "business man" 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.

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?

Trivia
When Nick says, "Shoot Me Again I'm not dead yet" may be a reference to Metallica's song "Shoot Me Again". As for singer James Hetfield says, "Shoot me again I ain't dead yet".

When Nick says "Are you really going to shoot a guy in a $10,000 suit, Come on!" it is most likely a reference to G.O.B. Bluth from Arrested development, who alienates his underlings by saying his suit is too expensive to be used on anything. e.g. "Oh yeah, the guy in the $25,000 dollar suit is going to be doing the heavy lifting. COME ON!" He  exaggerates the cost of his suit even more every time he says it.
