Halo Studios—previously known as 343 Industries—is a US-based video game developer located in Redmond, Washington and operating under the umbrella of Xbox Game Studios. Headed by Pierre Hintze, the studio oversees the development and management of the Halo franchise, producing titles both internally and in collaboration with external partners. Founded in 2007 following the separation of original creator Bungie from Microsoft, the studio’s name pays homage to the character 343 Guilty Spark.
After co-producing downloadable content for Halo: Reach, Bungie’s final entry in the series, 343 Industries released Halo: Combat Evolved Anniversary and initiated the "Reclaimer Saga" with Halo 4. This saga also encompasses Halo 5: Guardians (2015) and concluded with Halo Infinite in 2021. In October 2024, the company underwent a rebranding to become Halo Studios.
Formation
Bungie originally created Halo: Combat Evolved, which debuted as a launch title for Microsoft's Xbox after Bungie's acquisition in 2000. Due to cultural differences and disagreements over revenue sharing, Bungie regained its independence in 2007; however, Microsoft retained ownership of the Halo intellectual property. Xbox General Manager Bonnie Ross championed establishing an internal team dedicated to continuing the franchise, gaining approval from Microsoft Game Studios GM Shane Kim. Consequently, she founded 343 Industries, named after the iconic Halo character 343 Guilty Spark.
Beginning with a team of roughly twelve employees—including former Bungie franchise director Frank O'Connor and art director Kiki Wolfkill as studio head—343 Industries centralized control over the Halo narrative universe, working alongside external collaborators to maintain consistent development and strategic guidance.
Early projects
In July 2009, 343 Industries announced it was producing a seven-part anime anthology titled Halo Legends. Later that year, they introduced Halo Waypoint, an application designed to track players’ achievements within the Halo series. To strengthen its development capabilities, 343 Industries hired talent from the now-defunct Pandemic Studios and partnered with Certain Affinity on map packs for Halo: Reach. For the tenth anniversary of Halo: Combat Evolved, they commissioned Saber Interactive to create Halo: Combat Evolved Anniversary, which launched on November 15, 2011.
Reclaimer saga
Following Bungie's final contribution to the franchise with Halo: Reach, full responsibility for managing servers and data was transferred to 343 Industries on March 31, 2012. The studio completed Halo 4 by September 2012 and released it on November 6 as the inaugural chapter of the Reclaimer Trilogy, with plans for at least two more installments. During E3 2013, Microsoft and 343 revealed the next chapter for Xbox One; Microsoft Studios VP Phil Spencer later confirmed this trilogy would expand into what became known as the Reclaimer Saga. At E3 2014, the title Halo 5: Guardians was officially announced with a release date set for October 27, 2015. Microsoft collaborated with Mega Bloks to launch a new toy line connected to the saga; select Mega Bloks sets included exclusive content for the game. Since its release, 343 Industries has delivered free monthly updates for Halo 5.
At E3 2018, Microsoft Studios alongside 343 Industries unveiled Halo Infinite, originally planned for holiday 2020 launch across Xbox One, Windows PC platforms, and as a debut title for the Xbox Series X. The release was postponed until 2021 due to challenges related to pandemic-induced remote work arrangements. Notably, Infinite is unique among their titles as it was developed using 343’s proprietary Slipspace Engine.
Rebranding
Following the launch of Infinite, 343 Industries maintained ongoing support through various updates. On September 12, 2022, Bonnie Ross, the studio’s founder, resigned from her leadership position. Her responsibilities were distributed among three key executives: Pierre Hintze assumed the role of studio head, Bryan Koski was appointed general manager of the franchise, and Elizabeth Van Wyck took charge of business and operational functions. Amid widespread layoffs within Microsoft and the tech industry, 343 Industries underwent substantial organizational changes, with Bloomberg reporting significant shifts in their development strategies.
In October 2024, the studio underwent a rebranding initiative, adopting the name Halo Studios and transitioning its game development from the proprietary Slipspace Engine to Unreal Engine 5. A blog post on Halo Waypoint in July 2025 announced that Halo Studios would reveal their inaugural Unreal Engine 5 title during the October Halo World Championships. However, this period also saw internal layoffs coinciding with Microsoft’s larger corporate restructuring efforts. An anonymous former staff member described escalating "tension" surrounding projects "recently in crisis," highlighting a strategic move towards partnering with contracted studios across the United States and Europe instead of relying on individual freelancers. This approach aligns with development frameworks utilized by major franchises such as Call of Duty and Battlefield.
Additional workforce reductions in 2025 reflected continued cutbacks by Microsoft, with reports emphasizing dissatisfaction and internal difficulties within Halo Studios throughout this timeframe.
