Louis

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

- Moby Francke, Valve. "Well, it can only get better, right?"

- Louis

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, but in the game he is a Junior Systems Analyst at “Franklin Brothers” in the IT department located in Philadelphia PA, until the second day after the first infection. In official media, he is usually seen wielding a Submachine Gun or dual Pistols.

Louis, along with Zoey and Francis, appears in Left 4 Dead 2 in the campaign The Passing as they meet with the Left 4 Dead 2 Survivors. By the events of The Passing, it seems that Louis has somehow damaged his legs and is unable to stand on his own. Due to this he mans a Heavy Machine Gun during the campaign's finale.

Louis' facial features are portrayed by Sean Bennett and he is voiced by Earl Alexander.

Background
Before the Infection Louis was working as the Junior Systems Analyst at Franklin Brothers in Philadelphia, Pennsylvania. During his lunch breaks, he would often visit the shooting range which his co-workers would mock him for doing so. It can also be assumed he also played PC games as he has a figurine of the Heavy from Team Fortress 2 on his desk and mentions Counter-Strike when picking up a gun. Two days after the Infection began, he encountered his first Infected in the men's restroom after trying to convince a co-worker that the press was over reacting and everything was still safe. After killing the Infected, he exited the restroom only to find his office in shambles, his co-workers all dead, and the outside world falling to pieces.

Relationships with other Survivors
Louis is the most upbeat Survivor and attempts to keep the group's spirit's up.

Louis is somewhat saddened by Bill's death in The Passing, going so far as to kill a Tank in his name.
 * Bill: Louis and Bill do not appear to have much of a relationship. Louis does seem to like Bill, however, as he will cheerfully tell Bill that stairs are good for his cardio when Bill complains about them. He also wants to go save Bill when he's incapacitated outside the safe room.
 * Francis: Francis appears to be annoyed by Louis's cheerful disposition . Louis is perhaps more hostile to Francis than he is to any other Survivor (which isn't saying much), but is still willing to save Francis when he is incapacitated outside a safe room.
 * Zoey: Zoey teases Louis throughout the campaigns   . Louis' optimism seems to be appreciated by her, and they both become saddened and a little more emotional when the other dies  . In The Passing she shows deep concern for his injury, mentioning to the Left 4 Dead 2 Survivors they have a wounded man up there.
 * Coach: Coach and Louis seem to understand each other's situation quite well; both men are optimistic and want to want to keep in good spirits. Louis wishes Coach luck, and Coach offers generously to take Louis (and the other Survivors) with them to New Orleans.
 * Ellis: Louis and Ellis share an optimistic outlook, and they are quick to wish each other the best. Louis seems to find Ellis' comments amusing and claims the young man will "definitely make it to New Orleans."
 * Nick: Nick is the only Survivor Louis seems to dislike due to Nick's dismissive attitude toward him. He does not wish him luck at the end of The Passing and agrees with Francis when he claims "Bill would've shot him by now." Nevertheless, Louis will cover everyone, including Nick, during the battle. Sometimes upon finishing the finale, players will hear Louis wish everyone else good luck by their names and refer to Nick as "whatshisname".
 * Rochelle: Louis and Rochelle have an instantaneously warm relationship. When she sees him wounded, she takes his health into consideration, and she invites the trio to join them on their trip to New Orleans.
