Ellis

Ellis is one of the four playable Survivors in Left 4 Dead 2. He's a goofy, beer-loving smart guy that likes to work with machines. According to Chet, he is "extremely excited" about everything, like managing to visit a concert and kill a lot of zombies, making him more of an optimist like Louis of Left 4 Dead 2.

Official Description
Most people would be scared witless by the zombie outbreak. Not Ellis—he's 21 and indestructible, so there was no way he was getting infected. The Savannah native respects his mother, loves his job and enjoys the simple pleasures in life. A little cocky, it remains to be seen if the end of the world will show him fear for the first time.

Trivia

 * It seems that the designers have changed Ellis' clothing designs multiple times, going from a plain green cap and blue jeans with a white shirt, to a blue and white NASCAR-esque cap with bulky mechanic pants with a belt and some tools attached. This version also includes a T-shirt which has crossed flags drawn and words "J.B. Autoservice" painted under them, so it appears as his working T-shirt (This one is featured in the teaser trailer seen at E3 2009). Another one, introduced in the Dark Carnival gameplay footage features him in a more yellowish shirt and jeans instead of mechanic pants. His latest appearance features a T-shirt design that reads "Bull-Shifters". This makes him a survivor with the most skin changes seen on public.
 * Ellis holds a handgun using only his right hand unlike the other Survivors who use both of their hands as seen in this video.
 * Ellis also appears to hold the AK-47, Silenced Submachine Gun, Submachine Gun and, debatable, the Assault and Sniper rifles in an other way, like if they were shotguns.
 * It appears that Ellis was the one who drove the car from the first campaign's finale to Dark Carnival's Highway.
 * In the Zombie Survival Guide trailer, Ellis is the only one that is attacked by Special Infected. A Jockey, Charger, and a Smoker all try to attack him. This could imply that he is reckless and/or extremely unlucky.
 * Ellis was one of the only Survivors to have a skin, never featured in any game footage but screenshots. It can be seen in a picture above, featuring Ellis with a totally green cap, white shirt and jeans.
 * In the Zombie Survival Guide video, when Rochelle says "Kill all sons of bitches, right?" to Ellis, he gives a goofy, sheepish grin and nods. This may indicate that the two are fairly close, or perhaps show some romantic tension in the game. Ellis does yell 'I thought we were closer than that!' when receiving friendly fire from her, and when Ellis is talking about his friend Keith, she does call him 'sweetie', though she could be acting sardonic.
 * Ellis can be seen equipping three weapons at the same time in the Zombie Survival Guide; a grenade launcher, a sniper rifle, and a combat shotgun, which is not be possible in the game.
 * Ellis is the youngest character in Left 4 Dead 2, like Zoey in Left 4 Dead. Regardless, Rochelle's is 26, Nick is in his thirties, Coach is most likely around his mid or late forties, and Ellis is 21.
 * Ellis often tells stories about him and his friend Keith while inside the safe rooms.
 * Ellis' "Bull Shifters" shirt can be purchased for Xbox 360 avatars.
