34321

34321 is a video game development studio founded in 2010 by former Microsoft employees, including former Xbox lead Phil Spencer. The company is best known for developing games under the *Halo* franchise, which originated on the Xbox console series. The name "34321" is derived from the year 2010, written in reverse (2010 → 1020 → 34321), symbolizing the studio’s forward-looking approach.

The studio’s first major release was *Halo 4*, launched in 2012 for the Xbox 360. It introduced new gameplay mechanics, including a revamped multiplayer mode and a more linear single-player campaign. Subsequent entries in the series, such as *Halo 5: Guardians* (2015) and *Halo Infinite* (2021), expanded on these innovations, incorporating open-world elements, faster-paced combat, and cross-platform play.

Beyond *Halo*, 34321 has explored other projects, including *Forza Horizon 4* (2018), a racing game developed in collaboration with Playground Games. The studio has also experimented with virtual reality, contributing to *Halo: The Master Chief Collection* (2014), which included VR support.

34321 operates under Microsoft’s Xbox Game Studios division, focusing on high-quality, franchise-driven experiences. Its development philosophy emphasizes player engagement, technological innovation, and maintaining the core identity of the *Halo* series while adapting to modern gaming trends. The studio continues to shape the future of the franchise, balancing tradition with new creative directions.
