An article on GameInformer.com hears from Matt Charlesworth, a concept artist at Valve, who explains the process of redesigning Chell, the protagonist from Portal, who is getting a new look for the upcoming sequel to the first-person platformer. He describes their struggle with the idea of replacing Chell, how they toyed with changing her ambiguous racial background, and how they redesigned her outfit to look like it wasn't designed. There are character models and concept art showing the new direction Chell is taking, as well as a look at their co-op robots, which achieve "a very Westworld feel."
