• The Weapon (UNSC AI - CTN 0452-9): Master Chief's primary companion throughout the campaign. She interfaces with Forerunner and UNSC systems, provides tactical information, mission objectives, backstory, and emotional support. She can hack terminals, open doors, analyze data, and her developing relationship with Chief is a core narrative element. Not a direct combatant but crucial for progression and understanding the world.
  Artificial Intelligence
• Echo-216 ('The Pilot' - Fernando Esparza): Rescues Master Chief and pilots the Pelican dropship, serving as his primary means of transport between major landmasses on Zeta Halo (though not directly controllable by the player for free flight). He provides emotional commentary, narrative exposition, and represents the perspective of an ordinary human caught in the conflict. He does not participate directly in combat with Chief.
  Human (UNSC Contractor)
• UNSC Marines (Rescued Squads / FOB Support): Master Chief can rescue squads of captured UNSC Marines across Zeta Halo. Once rescued, they may assist in local skirmishes or can be called in as AI fireteam support (with varying weapon loadouts based on Valor progression) when Chief assaults Banished outposts or requests aid at a Forward Operating Base (FOB). Their effectiveness varies, but they can provide covering fire and draw enemy attention.
  Human (UNSC Soldiers)

• 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

• Spartan Cores: Found in distinct silver UNSC or Banished crates scattered across Zeta Halo, often in hidden areas or as rewards for minor encounters. Used by Master Chief to upgrade his five core pieces of equipment: Grappleshot, Shield Core, Threat Sensor, Drop Wall, and Thruster.
• Mjolnir Armor Lockers: Green UNSC lockers found throughout Zeta Halo. Each locker contains a unique cosmetic item (e.g., armor coating, emblem, weapon charm, AI color, stance) for use in Halo Infinite's multiplayer customization.
• UNSC Audio Logs: Data pads left behind by UNSC personnel before or during the Banished attack. These provide personal stories, tactical information, and lore about the UNSC's final stand on Zeta Halo and the events leading up to Master Chief's arrival.
• Banished Audio Logs: Data pads from Banished forces (Grunts, Brutes, Elites, Escharum himself). These offer insight into Banished culture, their motivations for being on Zeta Halo, internal conflicts, and their perspective on the war and Master Chief.
• Forerunner Artifacts (Rings / Archives): Mysterious Forerunner structures or data archives found across Zeta Halo. Interacting with them provides glimpses into Forerunner history, their conflict with the Flood and The Endless, and the purpose of the Halo rings. Unlocks entries in the Database.
• Skulls: Well-hidden collectibles, a staple of the Halo series. Each Skull, when activated for a new playthrough or mission replay, enables a gameplay modifier that typically increases difficulty or adds a humorous effect (e.g., Grunts explode into confetti, enemies have more health, no HUD).
• Propaganda Towers (Banished): Banished communication towers broadcasting propaganda across Zeta Halo. Destroying these towers (by disabling their power source) silences the broadcasts, earns Valor, and reveals nearby points of interest. Not a traditional 'collectible' but a clearable map icon.

• 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.

Shield strength can be upgraded using Spartan Cores. Does not have swappable armor pieces for stat changes in campaign; visual customization is for multiplayer.
• Shield Core Upgrades: Using Spartan Cores, Master Chief can upgrade his Mjolnir armor's shield generator, increasing the total number of shield segments (effectively more shield health) and potentially shield recharge rate or resilience.
• Multiplayer Armor Customization (Cores, Helmets, Chests, Shoulders, Knees, Visors, Coatings, Emblems, etc.): In Halo Infinite's free-to-play multiplayer, players can extensively customize their Spartan's appearance. Armor is based on 'Cores' (e.g., Mark VII, Mark V [B], Yoroi, Rakshasa, Eaglestrike) which act as a base. Players then equip various helmets, chest pieces, shoulder pads, knee pads, visors, apply armor coatings (color schemes), and emblems.

There are no options to change its visual design or color scheme within the campaign itself. Upgrades are functional (Shield Core, Equipment) rather than cosmetic.
• Multiplayer Spartan Armor Customization: Halo Infinite's free-to-play multiplayer features an extensive armor customization system.

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.

A Collector's Edition was available with physical items like a SteelBook case, art prints, plasma pistol bottle opener, and in-game bonuses.

Campaign co-op (up to 4 players online) and Forge mode (map editor) were added in major post-launch updates. No major paid story expansions for the campaign have been released as of mid-2024, but 343i has mentioned future 'story drops'.

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: Is Halo Infinite's campaign open world?
  A: Halo Infinite's campaign features a 'semi-open world' or 'wide-linear' design for a large portion of Zeta Halo. Players can freely explore large, interconnected regions, tackle main missions, and engage in numerous side activities like liberating FOBs, destroying Banished strongholds, and hunting High-Value Targets. However, it's not a fully seamless single open world; progression to new major landmasses is often tied to story advancement.

  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 the new Slipspace Engine, Halo Infinite showcases detailed environments on Zeta Halo, from lush forests and Forerunner structures to Banished fortifications. It features dynamic lighting, weather effects, and detailed character/weapon models. While the initial campaign visuals received mixed reactions, subsequent updates and the multiplayer's art style have been generally well-received. Ray tracing for sun shadows was added to PC and Xbox Series X post-launch.

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 Gareth Coker, Curtis Schweitzer, and Joel Corelitz, featuring a blend of classic Halo orchestral themes with new, more atmospheric and emotional pieces that reflect the open-world setting and narrative tone. Sound design includes iconic Halo weapon sounds, distinct alien vocalizations (Banished taunts, Grunt screams), vehicle effects, and immersive environmental audio. The classic Halo 'monk chant' theme is prominently featured.

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.

Classic Halo first-person HUD displaying shields, health (when shields are down), ammo count, grenade count, equipped weapon, and radar (motion tracker). Objective markers and threat indicators are present. Menus for multiplayer customization, campaign map (Tac-Map), upgrades, and database (lore) are accessible. The Tac-Map in campaign is crucial for navigating Zeta Halo.

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 full controller and keyboard/mouse remapping, extensive subtitle and caption customization (size, background, speaker names), colorblind modes, options for aim assist strength, options to change hold actions to toggles, UI narration, text-to-speech and speech-to-text for chat, and various visual/audio adjustments.

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.
