The following legend of Belly of the Beast 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.
Starting Points are specific locations where players begin each of the game's 22 chapters. These points serve as the initial spawn or entry point for the Doom Slayer.
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.
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.
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.
Hurl the Shield Saw at green flash nodes to lodge the shield into them. While the shield is embedded in the green flesh, press the shield throw button again to pull yourself toward it. Using the Shield Recall jump enables you to traverse wide gaps and reach higher elevations with ease.
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.
