The PlayStation platform holder said in a statement issued to Game Informer that the developer was closed as part of its "resource re-alignment" strategy.
Zipper was also behind the PS Vita title Unit 13 and the multiplayer online shooter MAG. Sony confirmed that all of its games will continue to be supported.
"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," said a spokesperson.
"Zipper titles MAG, SOCOM 4 and Unit 13 will continue to be supported, including the new Daily Challenges in Unit 13."
Zipper employed approximately 80 members of staff.
