Louis

"One distinguishing characteristic about Louis is that he represents the 'every day' man."

- Moby Francke, Valve.

Louis is one of the four playable Survivors in Left 4 Dead. His original concept was an assistant manager at a local retail electronics chain store. Now he is a Junior Systems Analyst in his company's IT department. His clothing resembles the typical business man, but bears a resemblance to Shaun from Shaun of the Dead, who wore a red tie and white shirt. In official media, he is usually seen wielding a submachine gun or dual pistols. He is voiced by Earl Alexander.

Official description
Louis had been working up the courage to quit his job as Junior Systems Analyst at his company's IT department when a virus showed up and downsized the world. Now Louis has a new set of goals (live long enough to succeed) and a new set of tools (guns, sharp objects) to help him achieve them. With any luck, he'll figure out how the new management operates before they get a chance to murder him.

Trivia

 * Louis's attire resembles Shaun from Shaun of the Dead, who wore a red tie and white shirt. His character also somewhat resembles Ben from the remake of George A. Romero's Night of the Living Dead, who, surprisingly enough, wears more or less the same clothing as Louis apart from the red tie.
 * Along with Francis, Louis is very friendly towards Zoey, and Zoey seems to be exclusively friendly toward Louis as well.
 * One of Louis' lines mentions Counter-Strike; a highly successful franchise also developed by Valve
 * His quote involving, "I ain't got time to bleed," is a reference to the same quotation by Jesse Ventura in Predator, and also refers to Duke Nukem 64/3D.
 * Louis' comments involving pills have become something of an internet meme, usually portraying him as being obsessed with or even addicted to them.
 * It should be noted that a lot of zombies also wear white shirts, and Louis tends to get shot because of this, prompting to ask "Do I look like one of them?!"
 * The beta version of Louis very much resembles the character Michael from the television series Lost.
 * In the intro when he gets pounced by a Hunter, he shoots it with his left hand. This could possibly suggest that he is left handed. However, in-game, he shoots with his right hand like the other Survivors.
 * If Louis gets shot by Francis he will sometimes state: "Go on! Do it one more time fat man!". This is a quote left behind from the beta version, in which Francis was overweight.
