One of the masterminds behind Portal, Valve designer Kim Swift, has left the studio. Gamasutra reports Swift has left Valve to become a project lead at developer Airtight Games, who is currently finishing work on Dark Void for Capcom. It's unknown what project Swift will work on, but she will apparently be part of a team creating games aimed at "a more diverse audience."
"I've learned so much and had some amazing experiences at Valve," said Swift in a brief statement regarding her decision to leave Valve. "But when I heard I had the opportunity to work on innovative titles with my friends over at Airtight, I couldn't pass it up."
Swift also contributed to the recently released Left 4 Dead 2.
Portal 2 has never been officially announced, but Swift has alluded to work on furthering Portal within Valve since the game's release. Valve has not yet commented on Swift's departure.
