Series 2: Spark

Season 2: Spark was the second Season implemented into Halo: The Master Chief Collection. The Season debuted on July 13, 2020, with the launch of Halo 3 as part of the collection on Steam and Windows. Although launching alongside Halo 3, the cosmetic unlocks available focus on adding new Skins for Halo: Combat Evolved multiplayer alongside new nameplates. This season was preceded by Season 1: Noble and is followed by Season 3: Recon with the launch of Halo 3: ODST for PC on September 21, 2020. The season's logo is a stylised representation of 343 Guilty Spark.

Seasonal events and challenges
Season 2 saw the launch of the Challenges feature in The Master Chief Collection. To celebrate the launch of Halo 3, two limited-time challenges were introduced to unlock the Acrophobia Skull and Alliance Nameplate. Additionally, a number of season-long challenges were introduced to earn the gold skins for the Assault Rifle, Shotgun, Pistol and Sniper Rifle alongside XP and rewards.
