This article is about the Halo: Reach helmet. For the ship classification that Ace of Spades belongs to, see Mariner-class transport ship.
Similar to EVA, the Mariner base helmet features a bowl-shaped visor, which surrounds the user's face, meeting with metal armor plates along the jaw and back of the head. Either side of the helmet, there is an additional layer of armor that follows the wearer's jawbone up to their ear and the side of their head, and appears to connect up at the back of the head. Just behind the user's ears on either side, there is what appears to be a circular hardpoint for securing attachments like optics to the helmet.
The helmet can be equipped with an additional layer of metal plating, which covers the top of the visor, directly above the user's head. This piece of armor bisected by an extra piece of plating that curves over the top of the wearer's head and stops just shy of the user's eyeline. It can also be equipped with some form of optics, in the form of an eyepiece which is secured to the front of the visor using the two aforementioned hardpoints either side of the helmet. The attachment itself is a rounded, goggle-like apparatus that sits where the visor would be on a traditional helmet. In front of the left eye, the eyepiece module features a large lens jutting out from its front. Meanwhile, in front of the right eye, it features two smaller circular protrusions above and below the user's eyeline. These two attachments can both be equipped at once.
During the production of the Defiant Map Pack, two additional armour sets were also produced, codenamed
The existence of the helmet that would become Mariner 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 helmet was not featured in the port at launch, however.
Eventually, in September 2020, 343 Industries confirmed that the helmet had been finalised and polished for inclusion in the game, would be available as part of Season 4: Reclaimer of MCC, alongside all of the other armor pieces from the two sets: AKIS, EXO/TSCS and "Preserve". However, it was later delayed, due to difficulties encountered during development.
The helmet's name, "Mariner", was officially revealed on the MCC Development Update on November 2020, along with the confirmation of both AKIS and Mariner helmet being present in Season 5.
