Marathon: Items Explained – Mods, Consumables, Currency and More!

Learn how Marathon items work, including rarity levels, weapon mods, cores, implants, consumables, key cards, and more! Video guides are also available.

The Important Details

  • Items are part of your build, not just your backpack. Marathon’s customization loop is built around moddable weapons, implants, and core system upgrades tied to your Runner shell.
  • Focus on swapping weapon mods, cores, and implants outside a run rather than in the heat of the moment…you never know who or what is lurking nearby.
  • Consumables are your survival layer. Current guides consistently frame healing, shields, debuff-cleansing, and utility consumables as high-value inventory decisions during extraction runs.

ITEMS OVERVIEW & RARITIES

Season 2: NIGHTFALL Item Watch: Season 2 brings new weapons, The Cradle stat customization system, faster faction progression, and a full item/Vault reset. Use your best gear before the reset, redeem unclaimed gear packages, and expect item priorities to shift once Night Marsh and the new gear pool arrive.
  • Items are the gear and support tools you bring into, find during, and extract from a run.
  • They generally fall into a few main buckets:
    • Weapons
    • Weapon mods / attachments
    • Cores
    • Implants
    • Consumables
    • Ammo, loot, and other carried resources
  • Marathon has a buildcrafting system built around moddable weapons, body implants, and core upgrades.

WEAPONS AND WEAPON MODS

  • Your Runner shell is your foundation.
  • Your cores and implants shape how that shell performs.
  • Your weapons can be tuned through mods and attachments.
  • Your consumables help you survive fights, recover, or counter threats mid-run.
  • A few notes:
    • You can swap cores, implants, and weapon mods outside a run.
    • Inspecting a weapon outside a run opens the mod workbench.
    • Not all cores are universal; only Standard (gray) cores work on every shell, while others are shell-specific.
Tip! Equip an Enhanced Backpack to add additional spaces to your backpack, allowing you to loot more in your run! Note that if you fail to exfil, you also lose that enhanced backpack!

WEAPON RARITIES

  • Item rarity follows a tiered color-coded system that indicates the value, complexity, and scarcity of gear.
  • Notably, weapon rarity is dynamic and primarily determined by the quality and/or number of attachments or mods currently equipped on the gun.

HOW RARITY WORKS

  • Weapon Scaling: Unlike other shooters where a “Rare” gun is a fixed drop, a gray magnum can become a blue magnum if you install higher-tier attachments, like a blue barrel.
  • Gameplay Impact: Higher rarity doesn’t just buff stats; it can introduce unique mechanics like invisibility backpacks or burst-fire shotguns.
  • Acquisition: Most loot in standard containers is gray or green.

RARITY LEVELS

  • The standard progression of rarity, from most common to most coveted, is as follows:
    • Standard (Gray/White): Common base items and resources with no or basic mods.
    • Enhanced (Green): Uncommon tier, often containing basic improvements or low-level key cards.
    • Deluxe (Blue): Rare items that typically offer better stats or more attachment slots.
    • Superior (Purple): High-tier gear with advanced effects, often found in locked rooms requiring purple key cards.
    • Prestige (Gold/Yellow): The most elite tier, providing significant gameplay shifts or “special effects” that change how a weapon functions. For Destiny players, this would be considered exotic-level.
    • Red: A highly exclusive rarity level found only in endgame activities, such as Cryo Archive. 

WHAT SHOULD YOU BRING INTO A RUN?

Run Type Bring This Why It Matters Runner Tip
Beginner Run Basic weapon, light ammo, Patch Kit, Shield Charge, and a low-risk backpack. Keeps your risk low while you learn routes, loot locations, enemy pressure, and extraction timing. Do not bring anything you are afraid to lose. The goal is survival and map knowledge.
Loot Run Larger backpack, healing item, Shield Charge, cleansing item, and flexible weapon ammo. More space means more value, but better supplies help you survive long enough to extract with it. Leave once the run is profitable. Greed gets loud fast.
PvP Run Reliable weapon, tuned weapon mods, strong shield, grenades or combat equipment, healing, and ammo reserves. Player fights usually come down to preparation, positioning, shield management, and whether you can recover after the first trade. Build for the fight, but always keep an extraction route in mind.
Solo Run Self-Revive, Patch Kit, Shield Charge, escape utility, and a weapon you can trust under pressure. Solo players have fewer safety nets, so recovery tools and escape options matter more than raw aggression. Pick fights carefully. Winning one fight can still leave you weak for the next squad.
High-Tier Room Run Key or keycard, full healing setup, Shield Charges, strong weapon, extra ammo, and a planned exit route. Locked rooms and high-value areas attract attention. The loot is better, but the pressure rises quickly. Open the room, loot with purpose, and leave before nearby teams collapse on your position.
Recovery Run Cheap weapon, minimal supplies, empty backpack space, and a simple plan. Useful after a losing streak when you need supplies, credits, or basic gear without risking your best items. Avoid unnecessary fights. Your win condition is leaving with more than you brought in.
Endgame Run Best available weapon, strong shield, multiple sustain items, utility equipment, key items, and squad-ready support tools. Endgame zones and high-value objectives punish weak preparation, slow decisions, and bad team coordination. Go in with a goal. Wandering with expensive gear is just donating to another crew.

SEASONAL RESET

  • When a new season begins, all items in your inventory and Vault reset.
  • Use your best gear, redeem unclaimed gear/equipment reward packages, and avoid hoarding items you will lose.
  • Cosmetics, LUX, SILK, Rewards Pass progress, faction unlocks, and Cryo Archive Subroutines progress carry forward.
  • To learn more about Seasons, refer to our Seasons page.

WEAPONS AND WEAPON MODS

  • Weapons are one of the main pillars of your loadout.
  • In short…
    • Mods let you tune how a weapon behaves
    • Some improve consistency or handling
    • Some lean into utility or survivability
    • Some can push a weapon into a more specialized role
  • Mods can influence a weapon’s overall rarity/profile, and some specialized mods appear to alter how the weapon functions rather than just nudging stats.

AMMO

Light Rounds
LIGHT ROUNDS
  • Typically used by standard, high-rate-of-fire assault rifles and SMGs (e.g., Overrun AR).
  • They offer high stability but lower damage per hit.
Heavy Rounds
HEAVY ROUNDS
  • Used by high-caliber weapons like the Bully SMG or Demolition rifle.
  • They offer high damage and significant stopping power but often come with higher recoil.
MIPS Round
MIPS ROUNDS
  • Specialized ammo for high-damage, single-shot, or high-impact weapons, such as sniper rifles and shotguns.
Volt Battery
VOLT BATTERY
  • Used by energy-based weapons.
  • Sprinting slowly regenerates ammo.
  • Reloading a Volt weapon discards any remaining energy in the magazine.
Volt Cell
VOLT CELL
  • High-capacity, energy-based ammunition used for advanced, electrified weaponry.
  • They function as magazines for energy weapons (like the V75 Scar or V00 Zeus).
  • Sprinting slowly regenerates ammo.
  • Reloading a Volt weapon discards any remaining energy in the magazine.

WEAPON MOD TYPES

  • Customizable attachments that modify weapon stats and performance, with most weapons supporting 3-4 slots for components like Chip, Magazine, Barrel, and Grip mods.
  • These attachments can be swapped in your loadout, increase weapon rarity (e.g., green/blue), and are essential for maximizing combat efficiency.
  • Refer to the top left icons on the images below to understand which mods are for what weapon component.
  • Mods can be swapped by pressing ‘V’ (or your keybind) while hovering over a weapon in your loadout.
  • Mods can be found in the field or through supply drops.
  • The rarity of a weapon is determined by the rarity of the attached mods.
Chip Mods
CHIP MODS
  • Universal slot providing direct, core performance stat boosts.
Magazine Mod
MAGAZINE MODS
  • Changes ammunition capacity and reload behavior.
Optic Mod
OPTIC/BARREL MODS
  • Influences range, accuracy, and handling.
Grip Mod
GRIP MODS
  • Improves stability and control.

CORES, IMPLANTS, EQUIPMENT AND SHIELDS

  • Cores are closer to shell upgrades.
  • Implants are closer to passive perks and stat tuning.
  • Together, they help determine how your shell plays before you even fire a shot.
  • Not every core is universal, so shell compatibility matters.
Cores
CORES
  • Class-specific, high-impact modifiers that change how your Runner Shell operates.
  • You can equip two Cores per run.
    • They often add new mechanics or drastically enhance existing abilities, such as allowing a Vandal to turn their arm cannon into a mobility tool for rocket jumping or letting a thief use a second grapple.
  • They are usually locked to a specific Shell archetype (e.g., Recon vs. Triage).
Implants
IMPLANTS
  • Universal, wearable tech that can be used by any Runner Shell.
  • You have three slots (Head, Torso, Legs).
    • They primarily boost base stats (e.g., higher heat capacity, faster agility) and provide a random perk.
  • They provide raw stat enhancements rather than changing the fundamental mechanics of a skill, allowing for fine-tuning a build’s performance.
Equipment
EQUIPMENT
  • In-match tools (tactical gear) for survival or navigation.
  • These are generally items that directly aid in looting, survival, and escaping the map rather than modifying your character’s abilities.
  • Typically limited per run; there are various grenades and claymores, some for damage or survival, like smoke.
Shield Implants
SHIELDS
  • The primary defensive layer for your Runner Shell, crucial for surviving high-stakes encounters.
  • These occupy a specific, often missed, slot in your loadout.
    • They protect your health bar and can be upgraded for higher capacity (e.g., Enhanced Shields).
  • While implants provide minor survival buffs, the Shield is your main protection against damage.

CONSUMABLES EXPLAINED

  • Consumables are your emergency tools during a run.
    • Some restore health or shields.
    • Some clear dangerous status effects or software disruption.
    • Some boost mobility, cooldowns, or stealth.
  • It is recommended to bring a mix of health, shield, and cleansing consumables per run.

MEDICAL, SHIELD AND SURVIVAL CONSUMABLES

  • Patch Kits restore health.
  • Shield Charges restore shields.
  • Higher-tier medical items are stronger, faster, or more complete recovery tools.
  • Self Revive is especially valuable for solo play.
  • ONI Tip: Bring healing if you want your loot to survive longer than your optimism.
Patch_Kit
MEDICAL CONSUMABLES
  • Restores your health.
  • Higher rarity medical consumables restore more health.
  • Recommended to have on every run, if available. 
Shield_Charge
SHIELD CONSUMABLES
  • Restores your shield.
  • Higher rarity shield consumables recharge your shield to full, and faster.
SelfRevive
SELF-REVIVE
  • Allows for self-revive when downed.
  • This can be found around the maps, or sometimes purchasable via the armory once completing the Introducing NuCaloric Priority Contract and unlocking the Self-Revive item in the NuCal’s skill tree,
  • Self-Revive timing ranges from roughly 12–16 seconds, depending on your Revive Speed stat. 
    • 16 seconds when Revive Speed is 0
    • 12 seconds when Revive Speed is 100
  • Extremely beneficial to have on hand if downed by a PvE combatant.
PangeaKit
PANGEA KIT
  • Fully restores health, fully recharges shields, and removes hazardous status effects.
    • This includes removing negative effects like toxins and frost!

UTILITY AND CLEANSING CONSUMABLES

  • Some consumables fix problems instead of restoring health.
  • Mechanical cleanse tools remove physical or environmental effects, like getting hit by spores.
  • Software cleanse tools counter hacking or EMP-style disruption.
  • These are more situational than healing, but can save a run in the right zone or fight.
OS_Reboot
OS CLEANSE CONSUMABLES
  • Helps remove OS debuffs such as the effects of being hacked or from an emp blast.
  • Maximizes your Firewall stat for a duration, with added benefits the greater the rarity.
Mechanic_Kit
MECHANIC'S CLEANSE CONSUMABLES
  • Helps remove hazardous effects such as frostimmobilizeoverheat and toxin.
  • Maximizes your Hardware stat for a duration, with added benefits the greater the rarity.
Anti-Virus_Kit
ANTI-VIRUS CONSUMABLES
  • This allows you to safely enter the “Big Red Lockdown” force field zones without taking instant damage.
  • It acts as a protective buffer that slowly depletes while active, allowing runners to navigate high-threat, restricted areas, clear corruption, and secure high-tier loot.
  • It mitigates, but does not completely eliminate, the damage over time, allowing for temporary survival in restricted areas.
SignalJammer
SIGNAL JAMMER UTILITY CONSUMABLES
  • Temporarily scrambles your visual profile, obscuring your appearance to hostile Runners, UESC, and various sensors.
  • It allows you to safely pass through enemy mines, such as Claymores, and is ideal for escaping or sneaking past squads while carrying high-value loot.

PERFORMANCE AND STEALTH TOOLS

  • Some consumables are about momentum, not recovery.
  • Use them to move faster, recharge abilities, or avoid detection.
  • These tools are often strongest when used before a push, escape, or extraction attempt.
Cardio_Kick
CARDIO KICK CONSUMABLES
  • Provides a massive burst of stamina, allowing you to quickly rotate around a flanking squad or outrun a closing threat.
  • Temporarily spikes your Agility (movement speed) and Heat Capacity (stamina/overheat management).
  • Helps in chasing down enemy players or to get the frak out of intense combat.
Energy Amp
ENERGY AMP CONSUMABLES
  • Increases the recharge rate of your Runner’s primary and tactical abilities, the greater amount the higher the rarity.
  • It is ideal for use just before or during a heavy fight to allow for spamming abilities.
  • When paired with specific upgrades, it can allow for sustained, high-uptime abilities (e.g., permanent invisibility with certain builds).
  • Is your build ability-focused? Stock up on these!

KEY CARDS AND HIGH-TIER MATERIALS

End of Season 1 Key Update: Locked room keys are guaranteed to drop from Wardens for the rest of Season 1. Key Templates are temporarily Compromised instead of Fragile, requiring Matter Fixatives to charge them, and Deluxe keys have a chance to drop from wall safes.
  • Runners (players) can find high-value items like Gold Key Cards (e.g., Cryo Archive keys) to unlock restricted loot, along with premium materials like Alien Alloys, Ballistic Turbines, and Hazard Capsules.
  • These rare, prestige-tier items are often secured in locked rooms or high-tier vaults found in locations such as the Outpost’s Pinwheel Base.

VALUABLE KEY CARDS AND LOOT

  • Gold Key Cards/Prestige Keys: These open high-tier vaults and prestige-locked rooms, often in the Cryo Archive.
  • Purple Key Cards: These are considered high-tier, frequently opening special locked rooms containing elite gear like deluxe guns, mods, and backpacks.
  • Green Cards: More common than gold or purple, these can be found frequently in areas like the Rook map, offering access to lower-level locked areas.

Where can you find keys?

  • Warden Bosses, UESC Commanders, and specific lockboxes found in buildings with red flares are primary sources.

Prestige and High-Tier Materials

  • Alien Alloy: A high-value item often found in Cryo Archive vaults or Locked Rooms [Prestige].
  • Ballistic Turbine & Hazard Capsule: Rare materials needed for faction upgrades, typically locked behind Prestige keys in the Outpost’s Pinwheel Base.
  • Biogenic Alloy: Found in locked rooms and used for advanced upgrades.

If you or your team is using a key to unlock a key room, using that key will create a very large audio jingle, which can be heard by nearby combatants or players, even at a distance. Be careful runner. They may come for you.

HOW TO THINK ABOUT ITEM VALUE

  • Not every item is worth keeping.
  • Prioritize gear that supports:
    • Survival
    • Your shell build
    • Your weapon setup
    • Your extraction goal
  • Treat some low-impact consumables as “use now” items instead of stash items.
  • Backpack space matters, so every slot should justify itself, especially in more difficult maps like Outpost.

WHY ITEMS MATTER ACROSS SEASONS

  • Item knowledge will matter more over time, not less.
  • Marathon’s seasonal model expands the available gear and build options.
  • Understanding item roles now makes it easier to adapt when new metas and loadout paths emerge, especially at  season resets.
