Praetor Suit

The Praetor Suit is the armored suit worn by the Doom Marine in Doom 2016. The suit is given to the player at the very beginning and is worn for the entirety of the game.

The player can customize the Praetor Suit in-game in order to advance in-game and adjust to new threats.

Appearence
The suit is mostly dark green, silver, black and bronze in color, with slightly lighter legs and helmet. Both the coloration and the overall design of the suit seems to be made to resemble the original Doomguy appearance, though the Praetor Suit covers the Doom Marine's whole body, including his arms. In addition to this the Praetor Suit also appears much more technologically advanced, with a complex visor and internal systems which allows the Doom Marine to travel to Hell and return again unharmed. The suit is described as being made from nearly impenetrable material, and may be responsible for what appears to be the Doom Marine's superhuman abilities.

In-Game Description
UAC REPORT FILE: HGFLTGTV

''Additional relics were found in the tomb alongside the Doom Marine. Some incantation tablets, and an ancient combat suit which was given a name: the 'Praetor Suit'. When found, it was encased in an inscribed stone tomb. The suit was extracted from the rock, cleaned, and subjected to numerous tolerance tests, and found to be almost impervious to any damage. It appeared to have some mechanical function as well- small receptors on the gloves and chest plate that attracted Argent plasma and dissipated it through capillary tubes in the substructure. Markings on the armor were also consistent with images of a man (or humanoid) seen in several of the tablets and stones found on other expeditions. The same markings were also noted on the Helix Stone, ''

''Despite it being clear that the suit can be activated in some way, no method has been found to do it. It appears to be missing a component, likely the Doom Marine himself.''

In-Game Attributes
The Praetor suit in-game is more than just cosmetic. The suit can be upgraded via Praetor Tokens, found on dead guards, and Argent Caches. There are also so-called Rune Trial Stones, which allow the player to do certain minigame challenges to obtain Runes. All these different collectible items allows the player to obtain certain new abilities, and increase health, suit armor and ammo capacity.

The suit may also be upgraded with Delta V Jump-Boots, which allows the player to double-jump when obtained.

History
The suit was allegedly found alongside the resting Doom Marine in an ancient tomb in Hell, encased in stone. The UAC managed to extract both the Doom Marine and the Praetor Suit and bring them over to Mars. In scriptures found in Hell, the Doom Marine described as having been a very powerful man, known as the "Doom Slayer" and "Scourge of Hell" by the demons, which tried for "eons of time" to defeat the one man who they could never destroy. In the end, after having been the nightmare of even the bravest of demon lords, and having defeated the gigantic Titan, the Doom Marine was eventually captured and deprived of his suit, after which he and the suit were sealed away in a tomb so that Hell would not be destroyed.

Origin
The suit is told to have been given to the Doom Marine by an entity only referred to as "the wretch". While the demons' scriptures claim that the armor was made in hell, closer examination reveals English text and even logos for human manufactures, suggesting the armor was actually made on Earth.

The Armor/Suit also appears to have rusted in certain areas, suggesting the suit is in-fact old, along with wear being shown as well, further supplying evidence of aging, the suit also has the number 8623, suggesting the suit was in-fact mass manufactured (which would make sense if the suit was manufactured by the Manufacturing plant for Marines) interesting enough all depictions of the Doom Marine show him in the Armor, further suggesting he arrived in the armor, it is also possible the reason why the Doom Marine had the "crown" of the sentinels was simply due to his armor, and how different it was from the Night Sentinels armor.

When the Doom Slayer also grabs the helmet in the introduction scene, he attempts to rub the Argent rune off it, suggesting the rune wasn't there before his capture by hell.

Anomalies
As mentioned there are various anomalies located on the armor, suggesting a possible Earth origin of Doom Marine's armor, despite it's purported hellish origin. Below are the anamolies:.
 * A Tag called D22, Possibly either referring either to the Doom Marine's soldier code or tag if he was a Marine, or a Model code for the Praetor Suit.
 * The Word CAUTION under the helmet's main exhaust, An English word, which would make no sense for the Doom Marine's suggested Argent background.
 * A Production stamp (lower left of helmet)
 * A Circular Icon with two circles (right arm shoulder pauldron) which could be an early UAC logo, Army squad/force logo, or manufacturer logo.
 * 1/0 Logistics Manufacture is mentioned on the armor several times.
 * 8623 could refer to either the amount manufactured until this specific set of armor, or the date of it's manufacture (i.e 8th of June 2123)

Trivia

 * The suit has appeared on numerous promotional artwork, including the Doom 2016 cover
 * The suit (or parts of it) may have been manufactured by 1/0 Logistics Manufacture, as this name is found on some places on the suit
 * The suit model is marked as "D22"
 * Apart from English text, the suit also dons a symbol which is also seen on the knight holograms, most likely being associated with the Doom Marine and those who fought beside him.
 * Praetor comes from the Latin Praetoriani meaning "Praetorian Guard" who were an elite squadron of soldiers in Ancient Rome who were used as protection of the Emperor.
 * Interestingly enough the Night Sentinels of which the Doom Marine was likely allied with in some way, were also elite soldiers, and bodyguards.
 * Praetor itself was a term referring to each of two ancient Roman magistrates ranking below consul.
 * The suit's helmet bears a resemblance to Quake 3 Arena's tutorial character Crash.
 * Originally, the Praetor Suit was not available to players in Multiplayer, however in the fifth free update this was changed, so that maximum ranked players could equip it. It is unknown whether or not this proves that the armor was mass produced (due to how MP's "lore" states it to be a simulation).
