UK studios Evolution Studios, Guerrilla Cambridge and SCE London Studio experienced layoffs this morning, a Sony spokesperson confirmed with Polygon.
Numerous employees from each studio have been affected, VideoGamer.com first reported, but the publication could not confirm the total numbers.
"Regular reviews take place throughout SCE Worldwide Studios, ensuring that the resources that we have in such a competitive business can create and produce high quality, innovative and commercially viable projects," a Sony spokesperson told Polygon. "As part of this process, we have reviewed and assessed all current projects and have decided to make some changes to some of our European Studios.
"As a result of this, there will be a focused restructure within London Studio, Guerrilla Cambridge Studio and Evolution Studio to ensure that the SCE WWS is in the best position to achieve their goals going forward," the statement continued. "Our first party development studios are key to our creative strategy and we are very excited about the future projects being worked on."
The "development of DriveClub will not be affected" by the Evolution Studios layoffs, Sony told VideoGamer.com. Earlier this month, PlayStation software product development head Scott Rhode said the often delayed DriveClub has gone "back to the drawing board" to ensure a high quality release.
Sony Santa Monica experienced a reduction in workforce in February, along with a cancellation of a new IP. Three key development heads have departed Sony Computer Entertainment subsidiaries in the past few weeks, including Uncharted creative director Amy Hennig, God of War 3 creative director Stig Asmussen and Infamous: Second Son lead designer Jaime Griesemer.
