Andrea Wicklund is an artist who worked at Valve.
Wicklund has a BFA in Illustration from the Academy of Art of San Francisco, which she attended from 1999 to 2003. She makes art for other various companies, and has been showing her art in exhibitions since 2003.
She made several pieces of concept art for Half-Life 2: Episode Three, posted on her Picasa account (now deleted) in March 2008. They were discovered by a source from ValveTime.net in June 2012. The images include several outfit variants for Alyx Vance (one with her wearing her father's jacket), several outfit variants of what may be Arctic Rebels, several variants of the Mil Mi-8 crashed into the ice (each including a facility in the background), and several images of Xen, including what may be a creature, islands, and a Combine Advisor cornering someone.
She created the drawings made by Doug Rattmann and seen in Portal 2. She returned for Portal 2: Lab Rat, of which she drew the main story, while Michael Avon Oeming drew the flashback scenes. Lab Rat also reincorporates her Rattmann drawings.

- Andrea Wicklund
- Once upon a time, Andrea was a disheveled, San Francisco artist, making a living as an illustrator. She did newsmaker profiles and such for Rolling Stone, Spin, and The Wall Street Journal, to name a few. Sadly, her life dream of illustrating children’s books fizzled, as her paintings, according to one art director, would “scare the children.” Which makes her perfect for Valve. She joined the company in late 2006. Since arriving, she’s done a little of everything, from character design to comic books (Lab Rat) to hand modeling. (Yes, Andrea is “the hand” of Left 4 Dead.) On her days off, she paints with real, non-electronic paint and listens to loud music—loud enough to drown out her singing voice.
