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. 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.

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.

Relationships with other Survivors
Louis is perhaps 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, even going so far as to kill a Tank in his name. ("That...is for Bill!") This also may hint at the fact that a Tank delivered the fatal blow to Bill before he died by the generator, which would also explain the blood streak to Bill's body.
 * 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 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. ("Bill! C'mon guys, let's go help 'im.")
 * Francis: Francis appears to be annoyed by Louis's cheerful disposition. ("Hey Mr. Positive! We just crashed! You got somethin' positive to say about that?"). 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 down outside a safe room. ("C'mon, aren't we gonna help him?")
 * Zoey: Zoey teases Louis throughout the campaigns ("Hey Louis, all of these cubicles make you homesick?") and ("Louis, your row isn't boarding yet.") Louis' optimism seems to be appreciated by Zoey ("You're an optimist, I'll give you that, Louis."), and they both become saddened when the other dies ("Goddammit, Zoey, wake up!" and "Louis! Oh God, I'm gonna miss you!" respectively).
 * Coach: Coach and Louis seem to understand each other's situation quite well; both men are optimistic and they seem 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 seem to 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. She is also the most understanding about the recent loss of Bill.
