Final Halo game made by Bungie, the creators of Halo.
The announcement trailer for the game was 77 seconds, or 1:17 minutes long. 117 is a reference to Master Chief's ID number, John-117.
On December 17th, 2015 Halo: Reach gained backwards compatibility support for Xbox One. Initially the game was wrecked with performance issues when played on Xbox One, with frame rates consistently in the mid 10's and low 20's, rendering the game unplayable. Fortunately in October, 2016 Halo: Reach received a patch that fixed the performance issues on Xbox One. Now the game runs better on Xbox One than it does on its native Xbox 360 hardware, with a steady 30fps refresh rate on Xbox One that rarely deviates.
This is the last Halo game to have Scarabs, Drones, Engineers and Brutes in it. Engineers, Brutes and Scarabs would later return in the spinoff game Halo Wars 2 (2017), but are yet to return in a main series game.
Like the Master Chief, Noble 6's face is unknown.
