343 Industries is an American video game developer and subsidiary of Xbox Game Studios based in Redmond, Washington. Headed by Bonnie Ross, the studio is responsible for the Halo series of military science fiction games, originally created and produced by Bungie, and the developers of the Slipspace Engine. Named after the Halo character 343 Guilty Spark, the studio was established in 2007, following the departure of Bungie from Xbox Game Studios, then called Microsoft Game Studios. After co-developing downloadable content for Halo: Reach, Bungie's final Halo game, 343 Industries released Halo: Combat Evolved Anniversary and Halo 4 to critical and commercial success – the latter starting the studio's "Reclaimer Saga" of mainline Halo games. The studio followed with Halo: The Master Chief Collection and Halo 5: Guardians, along with various spin-offs such as the Spartan Assault series and Halo Wars 2. 343 Industries is currently developing Halo Infinite as a launch title for Xbox's Project Scarlett – the successor to the Xbox One.
