Series 1: Noble

Season 1: Noble was the first Season implemented into Halo: The Master Chief Collection. The Season debuted on December 3, 2019, with the launch of Halo: Reach as part of the collection. Due to the launch of Halo: Reach, this season had an overarching focus towards Halo: Reach-related unlocks and customisation. The season's logo is a stylised representation of Mount Törött, the "broken mountain" commonly seen in Halo: Reach artwork.

Noble was followed by Season 2: Spark with the launch of Halo 3 for PC on July 14, 2020.

Season unlocks
The seasonal unlocks for Season 1: Noble take the form of the armor permutations that could be unlocked in the Xbox 360 release of Halo: Reach. For The Master Chief Collection, the unlocks have been divided into 10 tiers of ten unlocks each. To progress a tier, all ten unlocks within must be unlocked - at the season's launch, these unlocks were achieved sequentially with no user choice as to which unlocks could be achieved, but has since been updated with Season 2 to allow for the ten unlocks of any given tier to be achieved in any order.

Each unlock slot can be unlocked for, rewarded through the season's updated rank scheme or the Challenges implemented in subsequent updates.
