A Bit of Context
Halo: Reach is a first-person shooter set just before the original Halo: Combat Evolved, telling the story of the fall of the planet Reach and Noble Team. It was Bungie’s last main Halo game and the sixth overall title in the series, originally released exclusively for Xbox 360.
In later years, Halo: Reach became playable on newer hardware through Xbox One backward compatibility (2015) and as part of Halo: The Master Chief Collection on modern platforms, which helped it gain a new wave of players long after that 2010 launch.
TL;DR: If you’re wondering “when did Halo Reach come out” , the answer is September 14, 2010 (September 15 in Japan).
