As first reported last week by Kotaku, Zipper Interactive, the studio behind PS3-exclusive shooters like MAG and the SOCOM series, has been closed. Sony confirmed the closure in a statement this afternoon to Game Informer.

In the statement, Sony added that "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 itself acknowledged the end in a farewell Tweet moments ago. "After 17 years it's time to head off into the sunset. A sincere thank you to all our fans for everything you've done for us. Farewell."
