Supplies

In Doom (2016) and in Doom Eternal, the player receives supplies from two sources, namely through supplies placed on the ground, and from glory kill rewards.

Armor and medikits

 * Armor/health regained from bars, shields, chestplates, and medikits VARY across difficulties.
 * Armor/health Glory kill rewards DO NOT VARY across difficulties but VARY amongst enemy types.

Ammunition

 * Ammo regained from map supplies DO NOT VARY across difficulties.
 * Ammo glory kill rewards VARY across difficulties.
 * Ammo values found under difficulty columns are the amounts dropped from enemies after a Glory kill (GK).
