Halo: Chronological Order of the Halo Video Games

14 June 2025
The Halo franchise, developed by Bungie and later 343 Industries, spans centuries of interstellar conflict, artificial intelligence, and the legacy of ancient alien civilizations. While the games were released in a nonlinear order, the story unfolds across a tightly woven timeline that begins with humanity's first contact with the Covenant and stretches through the Forerunner saga, the Human-Covenant War, and the post-war rise of new threats.

This table presents all mainline Halo games and notable spin-offs in chronological order, aligning events based on in-universe year and narrative continuity  -  from the fall of Reach to the AI-driven revolution that follows the events of Halo 5.
