Series 4: Reclaimer

Season 4 will be the fourth season released for Halo: The Master Chief Collection, scheduled to begin alongside the launch of Halo 4 on PC platforms on November 17, 2020. It will feature new customisation items for Halo 3 and Halo 4.

Halo 3's items will take cues from the customization added to Halo: Combat Evolved in Season 2: Spark.

Originally, the season was to feature customization items for Halo: Reach, such as new helmets and armor pieces, a wider array of armor sets with the prosthetic arm, and the ability to equip armor effects to Elites, but difficulties during development forced the Legacy team to push this content back to a later season.

Season unlocks
Currently, the full extent of Season 4's unlocks has yet to be revealed, however the following items are confirmed:


 * Several Halo 3 skins for vehicles and weapons
 * Additional Halo 4 weapon skins from the Champions Bundle
 * Two never-released Halo 4 weapon skins, including the never before seen Blood (BLD) skin for the M395 DMR, and Blast (BLS) for the BR85HB battle rifle.

Part of the original content that was pulled out of the season was:
 * 2 new Halo: Reach helmets: AKIS, Unknown
 * 3 Halo: Reach helmet attachments for AKIS: GRD, CBRN, GRD/CBRN
 * 2 new Halo: Reach chest pieces: EXO/TSCS, Unknown
 * New combinations of chest pieces combined with the prosthetic arm for Halo: Reach
