Zoey

"Zoey unfolded into an everyday young woman who everyone can relate to."

- Andrea Wicklund, Valve.

"No one left behind, right?"

- Zoey

Zoey is one of the four playable Survivors in Left 4 Dead. She wears a white shirt, reddish pink track jacket, jeans, and black Converse shoes, and keeps her hair up in a ponytail. Zoey's original design was based off of Alesia Glidewell, who also worked with Valve on Portal as a model for the character Chell. However, when the character designs were updated later in development, Zoey was made to resemble actress Sonja Kinski instead. Ironically, her name means "life" in Greek. In official media, she is usually seen wielding dual Pistols.

Zoey, along with Louis and Francis, appeared in Left 4 Dead 2 in the campaign The Passing as they meet with the Left 4 Dead 2 Survivors.

Relationships with other Survivors
Overall, Zoey is perhaps treated the kindest by the other Survivors. In The Passing, unlike Francis and Louis, she rarely talks about Bill's death and seems to have been hit hard by the loss. Her tone and seriousness change when she talks about his death. Her aggressiveness towards the Left 4 Dead 2 Survivors might hint her struggle in coping with Bill's death.
 * Bill: In some ways, Zoey and Bill seem to have a father-daughter sort of relationship, and in general he seems to become slightly more emotional if Zoey dies ("Aghh... not [tearing up] Zoey.") when compared to the others. She also seems to care at least somewhat about his well-being at times ("We gotta take the stairs, sorry Bill.")
 * Francis: Originally, Valve intended Zoey and Francis to have a relationship, but this was deemed to be "distracting" by the play-testers. In her cut quotes, Zoey picks on him often ("Francis, I know how to cut hair. Just sayin...if you need it...I'm here."). Although their former relationship is no longer very evident, she still seems to be friendly towards him ("Groovy," which was something he'd said before). She's baffled by Francis' constant flirting with Rochelle, and claims she's going to throw up. On the other hand, she finds it cute that Francis still has "that side of him" deep down despite his tough guy attitude.
 * Louis: Zoey tends to tease him from time to time ("Louis... You'd look good in one of those hospital gowns."), and ("Hey Louis? Try not to get lost."), and becomes a little more emotional when he dies ("Louis, oh God I can't believe it!"). She has been placed next to him in every campaign poster so far. In The Passing, she is usually more concerned about Louis's well-being than Francis. She also briefly chokes up when she mentions they have wounded up on the tower at the Intro cutscene, indicating a concern for Louis's condition.
 * Coach: Zoey and Coach do not have much interaction. Though Coach will sometimes playfully pick on Ellis for his crush on her.
 * Ellis: Zoey seems to have a crush on Ellis (possibly due to their similar age). She mentions his name the most out of the Survivors and is the only one she is sad to see go. She calls out his name twice as he is leaving and wonders if she should have asked him to join her group. She also sadly states "I'm going to miss Ellis." Zoey will also playfully mimic Ellis's Keith stories as he is leaving. It's unknown if she knows Ellis also has a huge crush on her.
 * Nick: Zoey and Nick seems to have a strained relationship. He will sometimes insult her at the beginning of The Riverbank, and she will sometimes suggest to help everyone but Nick.
 * Rochelle: Zoey and Rochelle will often exclaim to each other how they are relieved to find another woman still alive. They will often compliment or thank the other's Special Infected kills in the finale, and Zoey seems happier to throw her an item than the other Survivors. However, she's baffled by the idea that Rochelle has feelings for Francis, claiming she's going to throw up at the thought of it.
