Praetor Suit

The Praetor Suit is the armored suit worn by the Doom Slayer in Doom 2016. The suit is given to the player at the very beginning of the game, and never after that taken off.

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

Description
The suit is mostly dark green, silver and brown 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 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 Catches. 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 and Origin
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.

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 Doom Marine is described as having traveled through worlds and time, suggesting that the Armor may very well be human in origin, and that the Doom Marine himself may have originated from another dimension, possibly the story of another game.

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.
 * Interesting enough the Night Sentinels of which the Doom Marine was likely allied with in some way, were also elite soldiers, and bodyguards.
