In Doom (2016), the Praetor suit's capabilities can be upgraded with Praetor tokens which can be salvaged from the suits of fallen UAC elite guards. In Doom Eternal, Praetor suit points can be acquired from Night Sentinel spirits or by completing combat challenges found in most levels; they perform an identical function to Praetor tokens.

Doom Slayer" is the main official title for this character in Doom (2016), Doom Eternal, and Quake Champions and is the title used for the Slayer's Testaments. Enemies killed by equipment or under the influence of equipment will reduce the equipment cooldown time. Demons swarmed into the labyrinth-esque corridors of Phobos, a Martian moon. And gamers met and destroyed Imps, Pinkies, and Barons for the first time. How the Doom Slayer travels through Worlds and Time might be the least important aspect of his history. Just that roughly all the games appear to take place in a single 'earth' timeline in some fashion or other. Parallel earth has not yet been confirmed in Doom series itself, though possibly hinted at in the Art of Doom Eternal (although it's part of Quake Champions', and MachineGames universe's stories, see Young Blood (B.J. mentions having traveled to or seen several Earth dimensions)). At some point the wide-eyed Doom Marine, found himself again newly transferred to Mars, the soldier got more than he asked for when Dr. Betruger betrayed the UAC. [23]The suit is retrofit with collectors for Argent energy in the chest plate and right fist, and the latter of these can be taken advantage of to allow use of Argent cells, which upgrade the marine's basic intrinsic statistics, including health, armor level, and ammunition carrying capacity. In the time of King Novik, as the Argenta secured peace and safety through dimensions across time and space, Doomguy is found by the Night Sentinels in a valley outside the castle walls on Sentinel Prime. How he arrived is unknown, though he was likely sent by demons to get rid of him. Sentinel scouts had found the Outlander bloodied, clawed and near death, mumbling of impending Doom and the forces of Darkness. The scent of blood followed him, and the gore that stained his armor seemed not entirely of his own. By Argenta law, he would be judged in the Coliseum, where he would be given the chance of all who stray from the Path to fight for his freedom. When an extra life activates, killing the demon that caused it to activate within a short time will cause the extra life to be regained. This rune cannot be used in Extra Life Mode or on Ultra-Nightmare skill level.

Ammo bars reworked (now weapons without reload have a single bar and ammo counter, grenades and C4 have now an ammo bar...)A life-sized figure of the Slayer made by Studio Oxmox for DOOM (2016) stands 205 centimeters tall, suggesting the Slayer was also the same height or slightly taller (about 6 feet 9 inches) in the previous installment (though he may be shorter without the base) [28]. An action figure of the Slayer made by ThreeA for Doom (2016) placed at one-sixth scale depicts the Slayer him slightly over one foot tall, placing him at 6 feet 7 inches or 2 meters [29]. In Doom (2016), the Slayer fist bumps his Doomguy counterpart when it is collected, a special animation not shown with any other collectible figure.
