In-game information
The "Preserve" chest piece will be unlockable in Season 4 of Halo: The Master Chief Collection.

Production notes
During the production of the Defiant Map Pack, two additional armour sets were also produced, codenamed  and. These were intended to be released alongside the Anniversary Map Pack later that year, but were cut due to time and resource constraints, as confirmed by 343 Industries employee David Ellis. "Preserve" consisted of this unidentified chest piece with the helmet now called AKIS, meanwhile "Condemned" consisted of an unidentified helmet and the chest piece now known as EXO/TSCS. Ultimately, none of the new armor was released for Halo: Reach on Xbox 360, though the AKIS helmet and EXO/TSCS chest piece were both seen in promotional material for the Defiant Map Pack, leading to much fan speculation.

The existence of the "Preserve" chest piece was not discovered until modder Gamecheat13 uncovered customisation renders of these two cut armor sets in the game files of the second Halo Insider flight (dubbed the "FireFlight") of Halo: The Master Chief Collection's PC port of Halo: Reach, in 2019. The "Preserve" chest piece was not featured in the port at launch, however.

Eventually, in September 2020, 343 Industries confirmed that the chest piece had been finalised and polished for inclusion in the game, would be available as part of Season 4 of MCC, alongside all of the other armor pieces from the two sets: AKIS, EXO/TSCS and "Condemned".
