Sony has closed Seattle-based firstparty studio Zipper Interactive.
Acquired by Sony Computer Entertainment in 2006, the Socom, MAG and Unit 13 developer is thought to have employed around 80 staff.
The news follows a report last week which claimed the studio had been hit with layoffs and that its closure was only a matter of time
Sony said in a statement issued to Game Informer: "Sony Computer Entertainment can confirm the closure of Zipper Interactive, a Seattle-based internal game development studio that has been part of the global development operation of Sony Computer Entertainment Worldwide Studios (SCE WWS).
"The closure is a result of a normal cycle of resource re-alignment within SCE WWS. Zipper has completed all work associated with its most recent project, Unit 13 for PlayStation Vita. Zipper titles MAG, SOCOM 4 and Unit 13 will continue to be supported, including the new Daily Challenges in Unit 13."
