Sony today confirmed it has closed Seattle-based game studio Zipper Interactive, the creators of the SOCOM series.

Responding to rumors last week, Sony representatives sent Game Informer the following statement:

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.

Zipper had approximately 80 employees.
