Bungie

Background
Bungie is an American video game developer based in Bellevue, Washington. Founded in May 1991 by Alex Seropian and originally headquartered in Chicago, Illinois, the studio is best known for their work with Microsoft during the latter's ownership, creating the acclaimed Halo series of console FPS games. In October 2007, Bungie split from Microsoft and signed a ten-year publishing deal with Activision in April 2010, while Microsoft retained ownership of the Halo franchise. In January 2019, the studio ended its partnership with Activision, and was acquired by Sony Interactive Entertainment in July 2022; despite this, Bungie continues to publish its games on its own.
