• Julianna Blake (Via Radio Comms & Invasions): While primarily an antagonist, Julianna is a constant presence via radio, engaging in witty, taunting, and sometimes informative banter with Colt. When she invades (as AI or another player), she acts as a direct, intelligent adversary, but not a companion.
  Human (Visionary)
• Themselves (Multiple Wenjies): Dr. Wenjie Evans has multiple versions of herself existing simultaneously in her lab due to time loop experiments. While these are all 'Wenjie' and act as enemies, they can sometimes interact with each other or be manipulated by Colt, creating a unique dynamic unlike traditional companions.
  Human (Visionary Clones)

• None (Gameplay): The Doom Slayer fights entirely alone during the single-player campaign. There are no AI companions that directly assist in combat.
• VEGA (Guidance/Narrative): While not a combat companion, VEGA provides crucial mission information, manages the Fortress of Doom, and contributes significantly to the narrative and lore exposition.
  AI

• Slabs & Slab Upgrades: Slabs (supernatural powers) are initially acquired by assassinating the Visionary who possesses them. Slab Upgrades are earned by defeating that Visionary again in subsequent loops, or by defeating an invading Julianna who is using that Slab. These upgrades enhance the functionality of each Slab (e.g., Shift can be upgraded to allow hovering or reaching further).
• Trinkets (Character & Weapon): Found throughout Blackreef in containers, on Eternalists, or as rewards for completing small objectives or puzzles. Character Trinkets provide passive buffs to Colt (e.g., increased health, double jump, faster movement). Weapon Trinkets enhance firearms (e.g., faster reload, increased accuracy, silenced shots, elemental bullets).
• Residuum: A shimmering energy resource collected from glowing objects, downed Visionaries, or by sacrificing unwanted Infused gear. Used at the end of each time period (Morning, Noon, Afternoon, Evening) to 'Infuse' weapons, Slabs, and Trinkets, allowing them to be carried over to the next loop. Essential for permanent progression.
• Documents (Notes, Letters, Schematics, Audiologs): Readable or listenable lore items found throughout all districts. They provide crucial backstory on the AEON Program, the Visionaries, Colt's past, Julianna's motivations, the nature of the time loop, and clues for assassinating targets or solving puzzles. Key to unraveling Blackreef's mystery.
• Weapon & Gear Tiers (Common, Rare, Epic - Indicated by color): Weapons and some Trinkets can be found in different rarity tiers, with higher tiers often having more perk slots or better base stats. Colt will typically seek out higher-tier versions of his preferred gear.
• Leads & Discoveries (Visionary Leads, Arsenal Leads): Information gathered by Colt that is tracked in his menu. Visionary Leads provide clues about targets' schedules, weaknesses, and how to manipulate events to line them up for assassination. Arsenal Leads point towards unique weapons or powerful Slabs/Trinkets.

• Toys (Vinyl Figurines): Small, hidden collectible figures representing various demons, characters, and items from the Doom universe. Each level typically has 2-3 toys hidden in secret areas.
• Codex Pages: Lore entries found throughout levels that expand on the game's universe, characters, demons, locations, weapons, and the history of the Sentinels, Maykrs, and Hell. Essential for understanding the deeper narrative.
• Albums (Music Discs): Hidden collectible records featuring music tracks from previous id Software games (like classic Doom, Quake, Wolfenstein) and some original tracks. These can be listened to in the Doom Slayer's room in the Fortress of Doom.
• Cheat Codes: Floppy disk-like items hidden in levels that unlock various cheat codes (e.g., infinite ammo, all runes, specific suit modes). Once found, cheats can be enabled when replaying missions but disable Slayer Gate access.
• Praetor Suit Points: Tokens carried by ghostly Sentinel guards or found in caches. Used to upgrade the Praetor Suit's abilities and systems.
• Sentinel Crystals: Crystals that allow the Slayer to choose between upgrading maximum Health, Armor, or Ammunition capacity. Unlocking both linked upgrades on a crystal grants an additional passive perk.
• Empyrean Keys: Earned by completing challenging Slayer Gates (optional combat encounters with high difficulty). Used in the Fortress of Doom to unlock the Unmaykr weapon.
• Sentinel Batteries: Power sources found in levels or earned from completing mission challenges. Used in the Fortress of Doom to unlock rooms containing collectibles like Praetor Suit Points, Runes, or cosmetic skins.

• No Traditional Armor System: Colt Vahn does not equip different pieces of armor with varying defensive stats. His survivability is primarily determined by his base health, which can be increased by specific Character Trinkets, and his skill in using Slabs (like Havoc for damage reduction or Aether for invisibility), stealth, and combat.
• Character Trinkets (Defensive Perks): Colt can equip a limited number of Character Trinkets that provide passive buffs. Some of these offer defensive benefits, such as increased maximum health, faster health regeneration, damage resistance, or reduced damage from specific sources (e.g., falls, explosions). These function as his primary 'armor' system.
• Slab Abilities (Defensive Uses): Certain Slabs, like Havoc (which absorbs damage and unleashes it), Aether (invisibility for evasion), or Shift (for quick escapes), provide significant defensive capabilities when used effectively.
• Reprise Ability: Colt has a built-in 'Reprise' ability that allows him to die twice within a single district/time period before the loop fully resets for that district attempt. This acts as a form of extra lives or resilience.

• Praetor Suit: The Doom Slayer's advanced combat armor. Provides base protection (Armor points) and can be upgraded with Praetor Suit Points to enhance various systems: Fundamentals (health, armor, ammo capacity), Environment (resistance to hazards), Frag Grenade, Ice Bomb, and Flame Belch (capacity, cooldowns, effects). Armor is a resource that absorbs damage before health and can be replenished by Flame Belching enemies or finding armor pickups.
• Runes: Up to three Runes can be equipped at a time, providing powerful passive abilities and buffs. Examples include 'Savagery' (faster Glory Kills), 'Seek and Destroy' (longer Glory Kill range), 'Air Control' (better mid-air maneuverability), 'Dazed and Confused' (longer enemy stagger time), 'Saving Throw' (survive one fatal blow).
• Sentinel Crystals: Collectible items that allow the Slayer to choose between upgrading maximum Health, Armor, or Ammunition capacity. Unlocking both upgrades on a crystal grants an additional passive perk.

• Colt Vahn's Attire (Default & Unlockable Skins): Colt has a signature default outfit (leather jacket, turtleneck). Players can unlock additional cosmetic skins for Colt through game progression, special editions (e.g., 'Party Crasher' skin), or updates. These change his appearance but offer no gameplay advantages.
• Julianna Blake's Attire (Default & Unlockable Skins): Julianna also has a default outfit and can unlock additional cosmetic skins for when she is player-controlled in the 'Protect the Loop' mode (e.g., 'Sharp Shooter' skin).
• Weapon Skins (Limited): Some unique or Deluxe Edition weapons come with specific skins. A broader weapon skin customization system is not a primary feature, though Trinkets can sometimes alter weapon appearance slightly or add visual effects.

• Doom Slayer Armor Skins: Players can unlock a wide variety of cosmetic skins for the Doom Slayer's Praetor Suit. These are earned through game progression, completing challenges, finding secrets, linking accounts (e.g., Slayers Club), participating in in-game events, or via DLC/Deluxe Edition. Skins range from classic Doomguy looks to unique demonic or Sentinel-themed designs but offer no gameplay advantages.
• Weapon Skins: Similarly, many weapons have unlockable cosmetic skins that change their appearance without altering their stats or functionality. Earned through similar methods as armor skins.
• Player Profile Customization (Podiums, Animations, Icons, Titles - BATTLEMODE): In BATTLEMODE, players can customize their Slayer and Demon podiums, intro/victory animations, profile icons, and titles to personalize their online presence.

• No Player-Controlled Vehicles (General Traversal)
  Colt Vahn primarily traverses the districts of Blackreef on foot, utilizing his parkour-like agility and supernatural Slab abilities (like Shift for teleportation). There are no player-drivable cars, bikes, or other traditional vehicles for general exploration within the districts.
• Tunnels / Access Points (Between Districts & Time Periods): Map Transition Mechanic
  Colt travels between the four main districts (Updaam, Karl's Bay, Fristad Rock, The Complex) and advances the time of day (Morning, Noon, Afternoon, Evening) by returning to his underground tunnels/bunker and selecting his next destination and time slot from a map interface. This transition involves a loading screen and is how the 'loop' progresses from one segment to the next.
• Contextual Traversal Aids (e.g., Ramps for Sliding, Cranes, Rooftops): Environmental Elements
  Levels are designed with verticality and interconnectedness, featuring environmental elements like ramps for sliding, rooftops for parkour, cranes, or other structures that Colt can interact with or use to his advantage for traversal and stealthy approaches.

• None (Player Controlled for Traversal)
  The Doom Slayer primarily traverses environments on foot, utilizing his advanced mobility (double jump, dash, climbing, meathook). There are no player-controlled vehicles like cars or bikes for general traversal.
• Fortress of Doom (Hub): Celestial Space Station / Hub World
  The Doom Slayer's mobile headquarters. While not a 'vehicle' in the traditional sense, it travels between dimensions and serves as a central hub where the player can access collectibles, upgrade weapons and suit, practice in a training room (Ripatorium), and select missions. It is not directly piloted by the player during gameplay missions.
• Contextual/Environmental Vehicles (e.g., Demonic Machinery, Lifts): Interactive Environment Elements

  A UAC employee hologram encountered in The Ancient Gods - Part One, providing humorous commentary and minor assistance.

• Visionary Leads (Assassination Storylines)
  The core progression involves pursuing 'Visionary Leads' for each of the eight targets. These are multi-step investigations across different districts and times of day, where Colt uncovers clues about a Visionary's schedule, habits, weaknesses, relationships, and potential ways to manipulate events to make them vulnerable or gather them with other targets. Completing these leads allows Colt to set up the 'perfect loop' to eliminate all targets in one day.
• Arsenal Leads (Weapon & Slab Acquisition)

Part Two sees the Slayer leading Sentinel armies against the Dark Lord in the heart of Hell to end the eternal conflict.
• Horde Mode
  A wave-based survival mode where the Doom Slayer fights increasingly difficult waves of demons across various arenas to achieve a high score and unlock cosmetic rewards. Features rounds with different objectives and random buffs/debuffs.

1. Protect the Loop (Online PvP): Players can choose to invade another player's game (who is playing as Colt) as Julianna Blake. Julianna's objective is to hunt down and kill Colt, protecting the time loop. She has her own progression, loadouts, and abilities. This mode can also be set to 'Friends Only' or 'Offline' (where Julianna is AI-controlled). 2. Single-Player Campaign (as Colt): The primary mode where players control Colt Vahn, attempting to assassinate the eight Visionaries and break the time loop, while also being hunted by an AI or player-controlled Julianna.

1. BATTLEMODE (2v1 PvP): An asymmetrical mode where two player-controlled demons team up against one fully-loaded Doom Slayer. Each demon has unique abilities and summons. 2. Invasion Mode (Canceled): A planned mode where players could invade another's campaign as a demon, which was ultimately canceled. Horde Mode was added as a single-player wave-based survival mode.

Available in Standard Edition and Deluxe Edition. Deluxe Edition included unique weapons (Transtar Trencher, Eat The Rich Tribunal, .44 Karat Fourpounder), character skins ('Party Crasher' Colt, 'Sharp Shooter' Julianna), and original soundtrack selections.

No major paid story expansions have been released.

The main post-launch content was the two-part story expansion 'The Ancient Gods - Part One' and 'The Ancient Gods - Part Two,' which continue the Doom Slayer's story after the main campaign. Numerous free updates added Master Levels (remixed, harder campaign levels), new BATTLEMODE arenas and demons, cosmetic skins, and quality-of-life improvements like Horde Mode.

• Q: What is the main objective in DEATHLOOP?
  A: The main objective is to break the time loop by assassinating all eight Visionaries on Blackreef island within a single day. This requires investigating their routines, finding ways to get them in the same place or eliminate them efficiently across four time periods (Morning, Noon, Afternoon, Evening) in four different districts.
• Q: How does the time loop mechanic work?
  A: The day on Blackreef resets at the end of the Evening, or if Colt dies three times within a single district visit (his 'Reprise' ability allows two revivals). When the loop resets, non-Infused weapons, Slabs, and Trinkets are lost, and Visionaries/Eternalists respawn. However, Colt retains all learned information (Leads) and any gear he has 'Infused' with Residuum.
• Q: What is Infusion and Residuum?
  A: Residuum is a resource Colt collects from glowing objects or by sacrificing gear. Between time periods (e.g., when returning to his bunker), Colt can spend Residuum to 'Infuse' weapons, Slabs, and Trinkets he wants to keep. Infused items will carry over to subsequent loops, allowing for permanent progression of his loadout.
• Q: Can another player really hunt you as Julianna?
  A: Yes, DEATHLOOP features an optional online multiplayer mode called 'Protect the Loop.' If enabled, another player can invade your game as Julianna Blake, with the objective of killing Colt. You can also set this to 'Friends Only' or 'Offline' (where an AI Julianna will invade).
• Q: Are Slabs like Dishonored's powers?
  A: Yes, Slabs are very similar to the supernatural powers found in Arkane's Dishonored series. They grant unique abilities like teleportation (Shift), invisibility (Aether), telekinesis (Karnesis), linking enemies (Nexus), and a combat buff (Havoc). They are acquired from Visionaries and can be upgraded.
• Q: Is DEATHLOOP connected to the Dishonored universe?
  A: While not officially confirmed as a direct sequel or prequel, there are numerous fan theories and subtle hints within DEATHLOOP (and Dishonored: Death of the Outsider) that suggest a possible connection or shared multiverse between the two Arkane franchises. However, DEATHLOOP can be fully enjoyed as a standalone story.

• Q: Is DOOM Eternal a direct sequel to DOOM (2016)?
  A: Yes, DOOM Eternal directly continues the story of the Doom Slayer from where DOOM (2016) left off, expanding significantly on the lore and universe.
• Q: What is the 'Doom Dance' or 'Funky Fetus' combat loop?
  A: This refers to the core gameplay loop of DOOM Eternal: aggressively engaging demons, using Glory Kills on staggered enemies to regain health, using the Chainsaw on weaker demons for ammunition, and using the Flame Belch to set enemies on fire and make them drop armor shards when damaged. This constant resource management through offensive actions is key to survival.
• Q: What are Master Levels?
  A: Master Levels are remixed versions of campaign levels with significantly increased difficulty, different enemy placements, and new challenges. They are designed for experienced players seeking a greater test of skill.
• Q: How does the Meathook on the Super Shotgun work?
  A: The Meathook is a grappling hook attached to the Super Shotgun. It can latch onto demons, rapidly pulling the Slayer towards them. This is used for aggressive closing of distances, setting up close-range shotgun blasts, aerial maneuvering, and can be upgraded to set hooked enemies on fire (generating armor with Flame Belch).
• Q: What is BATTLEMODE?
  A: BATTLEMODE is DOOM Eternal's 2v1 asymmetrical multiplayer mode where two player-controlled demons (choosing from types like Mancubus, Marauder, Revenant, etc., each with unique abilities) fight against one fully kitted Doom Slayer. It's a best-of-five rounds mode focused on tactical team play for demons and aggressive skill for the Slayer.
• Q: Does DOOM Eternal have ray tracing?
  A: Yes, ray-traced reflections were added to DOOM Eternal in a post-launch update for PC (NVIDIA RTX and AMD RX 6000 series and newer) and current-gen consoles (PS5, Xbox Series X). This feature enhances visual quality but is demanding on hardware.

Developed on Arkane's Void Engine, DEATHLOOP features a striking art style inspired by 1960s aesthetics, with bold colors, psychedelic patterns, and retro-futuristic designs. Blackreef's districts are visually distinct and detailed. The game uses stylized character models and environments, focusing on artistic direction over photorealism, though with high technical fidelity.

Powered by id Tech 7, DOOM Eternal boasts incredible visual fidelity and performance. It features highly detailed environments, gruesome demon designs, spectacular particle effects, and smooth, fast-paced animations. The engine is known for its ability to handle intense action at high framerates. Ray-traced reflections were added post-launch, enhancing visual quality on supported hardware.

Original score composed by Tom Salta, with contributions from other artists like Sencit Music and Erich Talaba. Features a distinctive soundtrack blending 1960s spy thriller themes, psychedelic rock, jazz, and electronic elements, creating a unique and memorable audio identity. In-game licensed tracks also feature. Sound design is crucial for detecting enemies, environmental cues, and the distinct sounds of Slabs and special weapons.

Iconic heavy metal soundtrack composed by Mick Gordon (main game) and Andrew Hulshult & David Levy (DLCs). The music is dynamic, intensifying with combat and perfectly complementing the aggressive gameplay. Sound design is visceral, with powerful weapon effects, distinct demonic roars, and satisfying feedback for Glory Kills and resource pickups.

Features a stylish, 1960s-inspired HUD displaying health, power (for Slabs), equipped weapons/Slabs, and objective markers. A leads system helps track clues and Visionary movements across districts and times of day. Menus for loadouts, Slabs, Trinkets, discoveries, and objectives are accessible. Colt's inner monologue and interactions with Julianna provide constant narrative and guidance.

Fast-paced and clear HUD displaying health, armor, ammo, Rad Suit/Oxygen levels, Equipment Launcher charges, Blood Punch/Flame Belch cooldowns, and available Chainsaw pips. Weapon wheel for selection. Codex entries provide extensive lore. Brightly colored pickups (health, ammo, armor) are easily identifiable in combat.

Offers a range of accessibility options, including customizable controls (PC), extensive subtitle and caption customization, options for aim assist strength, adjustable UI element size, colorblind modes, options to reduce head bob/motion blur, and various gameplay toggles for difficulty and HUD elements.

Includes a range of accessibility options: customizable controls (full remapping on PC), subtitle customization (size, background, speaker names), colorblind modes (Protanopia, Deuteranopia, Tritanopia), options to reduce camera shake and motion blur, adjustable UI opacity, and options for hit marker visuals and sound cues.

• Official PC system requirements from Arkane Lyon/Bethesda. Performance can vary depending on specific hardware, settings, areas in-game (especially those with many NPCs or complex geometry), and background applications. An SSD is strongly recommended for optimal loading times within the loop structure.
• Laptop Performance Note: Laptop models of listed desktop GPUs will require comparable performance, high TGP (Total Graphics Power), and good cooling. **DEATHLOOP can be demanding, particularly at higher settings or resolutions, due to its detailed environments and dynamic AI.**
• Laptop Consideration: G P U T G P: Good TGP is important for consistent framerates.
• Laptop Consideration: Cooling Thermals: Robust cooling is essential for sustained performance.
