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.

Season 2 was intended to release earlier in the year - likely coinciding with the release of Halo: Combat Evolved Anniversary for PC in February 2020 - though ended up delayed due to unforseen development issues (likely including the COVID-19 pandemic).

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.

Season unlocks
The seasonal unlocks for Season 2: Spark take the form of the skins for weapons, vehicles and visors in the multiplayer of Halo: Combat Evolved and nameplates for use in the menus. 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.


 * 41 Halo: CE Weapon Skins.
 * 5 for the Sniper Rifle (One unlockable via "The Exchange"; previously via Challenge)
 * 5 for the Shotgun (One unlockable via "The Exchange"; previously via Challenge)
 * 3 for the Rocket Launcher
 * 7 for the Assault Rifle (One unlockable via "The Exchange"; previously via Challenge)
 * 7 for the Magnum (One unlockable via "The Exchange"; previously via Challenge)
 * 3 for the Flamethrower
 * 4 for the Fuel Rod Gun
 * 4 for the Needler
 * 4 for the Plasma Pistol
 * 4 for the Plasma Rifle
 * 18 Halo: CE Vehicle Skins.

 * 3 for the Rocket Warthog
 * 4 for the Ghost
 * 4 for the Banshee
 * 4 for the Scorpion
 * 30 Halo: CE Visor Skins.
 * 30 Nameplates.

Each unlock slot can be unlocked for, rewarded through the collection's updated rank scheme or the Challenges implemented in the Spark update.

Challenge unlocks
Alongside the standard skins available to unlock for, four additional Gold skins were made exclusive to Season 2's timed challenges. Later on in Season 6: Raven, they were made purchasable in The Exchange on a weekly rotation for each.
