Halo Studios

Halo Studios is an American first-party game development studio and steward of the Halo universe. Operating within Xbox Game Studios and Microsoft, it was formed in late 2007 as 343 Industries following Bungie’s separation from Microsoft, with the remit to oversee and expand the science-fiction franchise.

The studio assumed full custodianship of the property with Halo 4 in 2012 and has since worked across mainline games, remasters, spin-offs, lore, live-action projects, comics, and competitive play. Its work spans first-person shooter development, multiplayer and cooperative systems, live-service operations, franchise management, and transmedia production.

Development and franchise work

Its credits include Halo: Combat Evolved Anniversary, Halo 4, Halo 5: Guardians, Halo Infinite, Halo: The Master Chief Collection, Halo Wars 2, Halo: Spartan Assault, Halo: Spartan Strike, and Halo: Fireteam Raven. The studio also manages the Halo Championship Series esports ecosystem and supports player community engagement.

For several years, the team developed the proprietary Slipspace Engine for Halo Infinite. In October 2024, 343 Industries rebranded as Halo Studios and shifted its core production pipeline to Unreal Engine 5. The change accompanied a broader effort to support multiple Halo projects and explore future experiences through the internal Project Foundry initiative.

In July 2026, the studio released Halo: Campaign Evolved, an Unreal Engine 5 remake of the original 2001 campaign with modernized visuals, cross-platform cooperative multiplayer, and new narrative missions. Halo Studios continues to support live operations, community work, engine research, and co-development stewardship for the franchise.
