The following legend of The Holy City of Aratum interactive game map defines the points of interest / markers displayed on the map. Each marker corresponds to a specific element to facilitate efficient navigation and interaction with the map.
The Starting Points in this chapter are the locations where players begin the game after landing on the hell carriers or secret platforms.
Secret Areas are hidden level sections containing collectibles like Codex Entries, Toys, Life Sigils, Gold, or Weapon Skins. To reach them, you will have to find hidden paths, obtain the necessary key, and so on.
Codex Entries are collectible items that provide lore and background information about the game's world, characters, enemies, weapons, and story. They are typically found in the Secret Areas or hidden locations within levels, rewarding exploration.
Collectible Toys, also referred as "Dolls," are hidden items scattered throughout the game's levels, typically found in the Secret Areas or in hard-to-reach spots. These toys are small, detailed models of characters or enemies from the game, serving as collectibles that reward exploration.
Skins are cosmetic items that alter the appearance of the Doom Slayer's weapons, offering no gameplay advantages. They are collectibles often found in the Secret Areas, hidden paths, or as rewards for completing specific challenges or levels.
The Doom Slayer's arsenal includes ranged firearms, melee weapons, a runic shield, and temporary Atlan mech weapons. All are acquired automatically through campaign progression, typically via pod drops or story events, ensuring no weapon is missable.
Arsenal can be upgraded at Sentinel Shrines with Gold, Rubies, and Wraithstones, enhancing damage, fire rate, ammo, or adding alternate modes.
Life Sigils are collectible power-ups that function as extra lives, allowing the Doom Slayer to instantly recover upon death without losing progress or restarting at a checkpoint. They are typically found in the Secret Areas or hidden locations.
Soul Spheres function as health and armor boosters. Picking up a Soul Sphere refills the player's health and armor to their maximum values.
Sentinel Shrines are special locations in levels where players upgrade weapons, shield, and melee abilities. Players use Gold, Rubies, and Wraithstones to unlock enhancements that boost combat effectiveness.
Demonic Essences are collectible resources obtained by defeating specific enemies called Leaders. These powerful enemies drop Demonic Essences when executed, which permanently upgrade the Doom Slayer's Health, Armor, or Ammo capacity.
Rubies are rarer, often hidden in tough-to-reach spots or gained from difficult encounters resources used to unlock higher-tier upgrades at Sentinel Shrines.
Gold chests, stacks, and bars provide gold, a base currency you gather to purchase most upgrades at Sentinel Shrines.
Keys are collectible items used to unlock specific doors, areas, or secrets within the game's levels. Keys are typically color-coded (e.g., blue) or labeled as "Secret Key".
Various types of switches, levers, valves, and similar mechanisms that need to be activated to open a passage, remove a barrier blocking a path, etc.
Closed passages, such as gates that require a key or specific actions to open.
Metal Locks that can be shattered by hurling a Shield Saw at them, which usually allows you to clear a blocked path. They can only be targeted when approached from the proper side.
Cultist Circles are hidden groups of cultists found in secret areas, often engaged in rituals, as part of mission challenges like "Countercult" or "Extreme Prejudice." Players must locate and eliminate all cultists in these circles to earn rewards such as Rubies or weapon skins.
Demonic Leaders are formidable demons in Doom: The Dark Ages. Defeating them rewards players with a Demonic Essence, granting a permanent boost to health, armor, or ammo capacity.
Encounters refer to combat scenarios where the Doom Slayer faces large groups of demons or specific enemies in the game's levels. These are intense, action-packed battles that test players' combat skills, often requiring strategic use of weapons, shields, and movement.
Points of No Return are specific locations in chapters where, once crossed, the Doom Slayer cannot backtrack to previous areas without restarting the chapter or reloading a checkpoint.
