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.

Zoey, along with 2 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 the A.I. Director chooses to kill.(However, it is likely that she is alive in canon, given that Chet Faliszek stated Ellis may develop a crush on her).

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 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!"). An interesting point to note is that she has been placed next to him in every campaign poster so far.
