Zoey

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

- Andrea Wicklund, Valve.

Zoey is one of the four playable Survivors in Left 4 Dead. She wears a white shirt, red jacket, jeans, and 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.

Zoey, along with the other Left 4 Dead Survivors, will appear in Left 4 Dead 2 in the campaign The Passing as they meet with the Left 4 Dead 2 Survivors, assuming that she is not the survivor who Valve announced dies before the events of the campaign (However, it is likely that she is alive, given that Chet Faliszek stated Ellis may develop a crush on her).

Official description
After spending her first semester holed up in a dorm room watching old horror movies, Zoey was given a choice: Stop fooling around and get her grades up, or drop out. Now that the planet's overrun with murderous zombies, and all of her professors are dead, Zoey at least has the cold comfort that she's been studying up on the right subject after all.

Relationships with other Survivors
Overall, Zoey is perhaps treated the kindest by the other Survivors.
 * 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).
 * Louis: Zoey tends to flirt with him from time to time ("Louis... You'd look good in one of those hospital gowns."), and frequently says somewhat random things directed to him as they go through the campaigns ("Hey Louis? Try not to get lost."), as well as becoming emotional when he dies ("Louis, oh God I can't believe it!"). An interesting point to note is that she has been placed next to him in every campaign poster so far.
