Season 4: Reclaimer is the fourth season released for Halo: The Master Chief Collection, and began alongside the launch of Halo 4 on PC platforms on November 16, 2020.[Note 1] It featured new customization items for Halo 3 and Halo 4.[2][3] The season's logo is a stylised representation of the Ur-Didact's Cryptum.

Halo 3's items took cues from the customization added to Halo: Combat Evolved in Season 2: Spark.[4]

Originally, the season was to feature customization items for Halo: Reach, such as new helmets and armor pieces, and a wider array of armor sets with the prosthetic arm, but difficulties during development forced the Legacy team to push this content back to a later season.[5] Nevertheless, armor effects for Elite player models in Reach were still implemented alongside Season 4, as intended.

Season unlocks

 
Keyart from Xbox.com showcasing some of the season's content.

The content of Season 4: Reclaimer involves that of the long-absent Champions Bundle weapon skins for Halo 4, along with additional skins for Halo 3, including newly implemented vehicle skins, with weapon skins now encompassing new weapons. New nameplates have also been added, being mostly Halo 4 themed in nature. The unlocks have been divided into 5 tiers of ten unlocks each. To progress a tier, all ten unlocks within must be unlocked, following in the footsteps of Season 3: Recon. Including Challenge unlocks, Season 4 introduces the following content to The Master Chief Collection;

All new Halo 4 skins are those which were previously useable in the game's original Xbox 360 release by way of the Champions Bundle, with two additional skins cut from the original launch of Halo 4 obtainable via seasonal Challenges. All skins previously in The Master Chief Collection remain unlocked by default. The new system of unlocks has also expanded the way Halo 4 weapon skins work. As well as being customisable on a per-loadout basis like in the original game, skins can also now applied universally, which will affect gametypes without custom loadouts, in addition to custom loadouts that do not explicitly override the universal setting. Unlike Halo: Combat Evolved and Halo 3 skins, Halo 4's skins still operate the way they did in the original game; only weapons that you spawn with will have your skin applied, and picking up a weapon will not change the skin it uses.

The Halo 3 Sniper Rifle Avalanche skin was unlockable by hitting Competitive Rank   in the timed Recon Slayer playlist. This challenge was started prior to the update's launch with progress carrying over to the final release. The challenge was timed, and ended on November 25, 2020.

Unlike Season 3, each unlock slot can be unlocked for   1 - rewarded through the collection's updated rank scheme or the Challenges implemented in the prior Spark update. In total,   50 are needed to unlock all content in Season 4.
