Zoey

Zoey is one of the four playable Survivors in Left 4 Dead. Her original design was based on 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/model Sonja Kinski instead. In official media, she is usually seen wielding dual Pistols.
