BioWare San Francisco has been shut down and its 25 to 30 employees laid off, a source within the company tells us. The studio, formerly known as EA2D, was best known for developing Dragon Age: Legends for Facebook as well as the browser-based Mirror's Edge 2D.
The studio, which focused on social and mobile games, was brought under the BioWare label in August 2011. Our source tells us Electronic Arts found it was "too expensive" to do mobile development in Redwood Shores, CA.
We've reached out to Electronic Arts for comment on the reports and will update this article with any response.
