For ''The Master Chief Collection'', the unlocks have been divided into 5 tiers of ten unlocks each. To progress a tier, all ten unlocks within must be unlocked.

===Challenge unlocks===
Alongside the standard ''Halo 3: ODST'' [[Armor permutations (Halo 3: ODST)|characters]] available to unlock for {{SeasonPoint|}}, four additional Firefight skins were made exclusive to Season 3's timed [[Challenges/Halo: The Master Chief Collection|challenges]]. These skins are ones found in the game's [[campaign]] as a consequence of events during the game's story, but left unused in the Firefight mode in the game's original [[Xbox 360]] release. Later on in [[Series 6: Raven]], they were made purchasable in [[The Exchange]] on a weekly rotation for {{SeasonPoint|2}} each.

==Production notes==
In the Flighting build for Season 3, the unlock system was to have included an additional nameplate known as Sirens (shown below), depicting the [[Genet]] vehicles employed by the [[New Mombasa Police Department]]. The nameplate was removed for the final release due to ongoing real-world controversy relating to the police.{{Ref/Site|D=01|M=6|Y=2020|URL=https://twitter.com/ske7ch/status/1295530704663506944?s=19|Site=Twitter|Page=Brian Jarrard|Quote=@Moses_FPS Hm well that’s obviously a nod to the New Mombasa police in ODST but yeah, agree it’s a sensitive direction in the current climate so we are going to address it}} In the flight, the nameplate was unlocked for {{SeasonPoint|1}} at Tier 39.{{Ref/Site|D=01|M=6|Y=2020|URL=https://www.youtube.com/watch?v=1088TVrAjUM|Site=YouTube|Page=Halo MCC - Season 3 New Content (Flight)}}

In the December 2020 update, the original Dino Tracker nameplate was removed and replaced with an updated design - part of a wider initiative across the nameplates and skins to remove ''Jurassic Park'' references from the game for reasons unknown. The original design is shown below; the nameplate was replaced with an updated Dino Tracker design with the same name and unlock requirement (shown in the above tables).
