• 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)

• Russell (Via Radio Comms): While not physically present, Russell is Alyx's constant companion via radio communication. He provides mission objectives, guidance, technical support, lore exposition, and humorous commentary throughout the game. He is crucial for narrative progression and player guidance.
  Human
• None (Physical AI Combat Companions): Alyx undertakes her physical journey through City 17 alone. She does not have any AI-controlled combat companions that follow her or fight alongside her in the traditional sense, emphasizing her vulnerability and resourcefulness in the VR environment.

• 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.

• Resin: Small, orange, cylindrical pieces of Combine material found scattered throughout all levels, often in crates, shelves, or hidden nooks. Collected and used at Combine Fabricator stations to upgrade Alyx's three main weapons (Pistol, Shotgun, SMG).
• Ammo (Pistol Clips, Shotgun Shells, SMG Power Cells): Found in Combine supply crates, on defeated enemies, or in the environment. Essential for combat. Alyx can store a limited amount on her person and in her backpack.
• Health Syringes: Medical items that restore Alyx's health. Found in medical kits, bathrooms, or sometimes dropped by Combine medics. Stored in wrist slots for quick access.
• Combine Grenades: Standard fragmentation grenades used by the Combine. Can be found in the environment or taken from defeated enemies. Stored in wrist slots.
• Grub Nests / Antlion Grubs (Healing Items - Minor): In Xen-infested areas, Alyx can find Antlion grubs in nests. Crushing them provides a small amount of healing. A nod to Half-Life 2: Episode Two.
• Vodka Bottles (For Jeff sequence): Specific to Chapter 7: Jeff. Vodka bottles are used as throwable distractions to lure the sound-sensitive creature Jeff away from Alyx's path.
• Battery Cells (For Multi-Tool Puzzles): Small cylindrical batteries that must be found and inserted into specific slots to power up doors, lifts, or other machinery as part of environmental puzzles solved with the Multi-Tool.
• Hidden Gnome Chompski (Easter Egg): A single, well-hidden garden gnome. Finding it and carrying it to a specific later point in the game unlocks an achievement, referencing a long-running Valve gag.

• Xen Grenades / Snarks (Implied/Contextual): Organic Throwable (From Xen Creatures)
  Players can often find and throw explosive Xen flora (like 'Boom Blobs') or potentially use Snark-like creatures found in specific containers, though these are environmental interactions rather than equippable weapons.

• Mjolnir Powered Assault Armor (Mark VI [GEN3] - Master Chief's Suit): Master Chief's advanced powered armor. Provides energy shielding (recharges), health (underneath shields), and integrates his equipment (Grappleshot, Shield Core, Threat Sensor, Drop Wall, Thruster). 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. These are primarily cosmetic and do not affect gameplay stats, promoting a balanced playing field.

• No Equipable Armor System: Alyx Vance does not have an equipable armor system where players can find or upgrade different pieces of armor for stat boosts. Her survivability is based on her base health, which can be restored using Health Syringes found in the environment or from Health Stations. Player skill in combat, using cover effectively, and managing resources are key to survival.
• Health Syringes & Health Stations: Health Syringes are consumable items stored in Alyx's wrist slots that provide instant healing. Wall-mounted Health Stations can also be found, allowing Alyx to restore her health by interacting with them (often requiring a puzzle or power to activate).

• Master Chief's Mjolnir Armor (Mark VI GEN3): In the single-player campaign, Master Chief's Mjolnir armor has a fixed appearance reflecting its latest generation. 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. Players customize their personal Spartan using: - **Armor Cores:** Base armor models (e.g., Mark VII, Mark V [B] from Reach, Yoroi samurai-themed, Rakshasa, Eaglestrike). - **Helmets:** Various helmet designs for each core. - **Visors:** Different colors and patterns for the helmet's visor. - **Chest Attachments:** Additional armor plating or gear for the chest. - **Shoulder Pads:** Left and right shoulder armor pieces. - **Knee Pads:** Protective gear for the knees. - **Gloves:** Different glove designs. - **Wrist Attachments:** Utility items or cosmetic pieces for the wrist. - **Utility/Hip Attachments:** Pouches or gear attached to the hip/thigh. - **Armor Coatings:** Overall color schemes and material finishes for the armor. - **Armor Emblems:** Decals that can be applied to armor pieces. - **Armor Effects:** Special visual effects like flames or energy auras (often from events or store). - **Mythic Effect Sets:** Themed sets that can change helmet, armor, and death effects. These are unlocked through the Battle Pass, in-game events, challenges, or purchased from the store. They are purely cosmetic.
• Weapon Coatings & Charms (Multiplayer): In multiplayer, players can apply cosmetic coatings (skins) to their weapons and attach small weapon charms for personalization.
• Vehicle Coatings & Emblems (Multiplayer): Multiplayer vehicles can also be customized with different paint jobs (coatings) and emblems.

• Alyx Vance's Standard Attire: Alyx wears a consistent outfit throughout the game, consisting of a practical jacket (often with a Black Mesa logo reference), shirt, pants, and her iconic fingerless gloves which house her health/ammo display and are part of the Gravity Glove system. There are no player-controlled clothing customization options for Alyx; her appearance is fixed for the narrative.

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.

Designed for VR immersion. Health and ammo are displayed on Alyx's left glove. Weapon selection is often done by reaching over the shoulder or via a wrist-mounted menu. The Gravity Gloves provide intuitive object interaction. Inventory (syringes, grenades, Resin) is managed via wrist slots or a backpack accessible by reaching behind the shoulder. Minimal on-screen HUD elements to maximize immersion.

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.
