Marathon Weapon Mods: Which Are Actually Worth It (Season 2)

Marathon's mod system looks like every other looter's: 6 rarities, 8 mod families, hundreds of entries. It isn't, and the difference decides how you spend every credit you take out of a run.

Every Prestige mod in the game is locked to exactly 1 weapon. There are 30 base weapons and 30 Prestige mods, and the mapping is 1-to-1. No gun has 2. None has zero. The Prestige description always opens the same way: "A custom-made mod for the …", and then it names your gun. Nothing else in the mod pool works like that; a Superior chip goes on whatever you like.

So the question people actually type, which Prestige mod is the best pick, has no answer, because you never choose between them. The real question is whether the gun you already run has a Prestige mod worth 24,000 credits. That is what the table further down answers, gun by gun.

2 consequences worth internalising before you save up:

• Buying the mod means committing to the gun. Drop the weapon and the mod is dead weight. It fits nothing else.
• Chips are the exception that proves the rule. The chip family has no Prestige tier at all. If you want a universal upgrade you can move between weapons, Superior chips are the whole game. See below, and they are the bulk of what Marathon weapon mod farming actually pulls.

Rarity in Marathon runs Standard → Enhanced → Deluxe → Superior → Prestige → Contraband. Most guides stop at Prestige. Contraband sits above it and is described as "very exclusive, high valued" gear rather than a mod tier you shop for.

The interesting part is the money, and it needs 1 honest caveat before the table. Only the Prestige row below is a fixed, universal figure. All 30 Prestige mods list the identical 24,000 credit cost and the identical 1,620 credit exfil value: 30 out of 30, no spread by family or weapon. Beneath Prestige, most database entries list no vendor cost at all, and exfil value varies mod by mod, so those cells are the typical entry rather than a rule.

2 things fall out of that, and both hold even on the cautious reading.

The step to Prestige is far bigger than the steps below it. 115 → 345 → ~1,035 → 3,105 is roughly a tripling each time. Carry that forward and Prestige should land near 9,300 credits. It costs 24,000, about 7.7× Superior. A 3× step would have put it near 9,300. Whatever the exact figures at the bottom of the ladder, the top of it is priced on a different curve.

And Prestige is by far the worst thing to hold. Every tier from Standard to Superior resells for roughly a 5th of what it cost. A consistent 5× loss. Prestige resells for 1,620 against 24,000, a 14.8× loss, 3 times worse than anything beneath it. That figure is exact. Both numbers are universal across all 30 mods.

The practical rule: never buy a Prestige mod as an investment, and never carry a spare Prestige into a run hoping to bank it. 1,620 credits does not justify the risk, and it is a rounding error next to what you paid. Buy Prestige only to bolt onto a gun you will still be using next week. For everything else, Superior is where the credits actually work, which is also why the mod runs we sell are priced per mod and per rarity rather than as a single package.

Here is every Prestige mod against the weapon it belongs to. Use the filter above the table to jump to your weapon class.

The tier column is a capability ranking. Nobody can measure 30 weapon-locked perks honestly in a single pass, and any site claiming a DPS order for these is guessing. It ranks something you can check yourself in the mod description: how much the perk changes what the weapon does.

• S. The perk gives the gun a capability it did not have: a new firing mode, a new projectile, silence, an extra charge level. These change your loadout. The numbers come after that change.
• A. A strong conditional swing in a fight: ramping fire rate, self-healing, ammo economy. Excellent, but the gun still plays the same.
• B. Utility and information: radar, sonar pings, hipfire accuracy, zoom. Real value, rarely the thing that wins the fight.
• C. Stat lines only, no unique perk. Nothing is in this tier. Every Prestige of the 30 carries a real perk. The entry that appears empty on community tables is a documentation gap. Bungie's Update 1.0.6 notes fill it: the V00 Zeus RG Overclocked Generator doubles magazine size.

Tier	Weapon	Class	Prestige mod	Slot	What the perk does
S	M77 Assault Rifle	Assault Rifle	Interval Mag	Magazine	Precision hits with iron sights build stacks; unlocks an alternative firing mode.
S	Overrun AR	Assault Rifle	Adaptive Mag	Magazine	Toggles a burst-fire mode. Body shots raise precision and aim assist briefly.
S	CE Tactical Sidearm	Pistol	Ghost Barrel	Barrel	Silences the weapon.
S	D54 Battle Pistol	Pistol	Daredevil Stock	Stock	Folded stock stacks hipfire power; unfolding converts stacks to a burst.

S	Copperhead RF	SMG	Triple Barrel	Barrel	Fires 3 shots at once in a fan pattern.
S	V85 Circuit Breaker	Shotgun	Overclocked Delimiter	Magazine	Adds a 3rd charge level with greatly increased output.
S	WSTR Combat Shotgun	Shotgun	MIPS Slug Converter	Barrel	Press to convert shells into a high-powered slug.
S	Outland	Sniper	Outland Suppressor	Barrel	Silences a sniper rifle.
A	Impact HAR	Assault Rifle	Stopping Mag	Magazine	Fires charged rounds that generate heat on targets.

A	Conquest LMG	Machine Gun	Infinity Belt	Magazine	Eliminations feed ammo straight into the magazine and raise fire rate.
A	Hardline PR	Precision Rifle	Adrenal Feedback Rounds	Magazine	Precision hits cut your shell’s heat and stack Micro-Adrenaline.
A	Repeater HPR	Precision Rifle	Lever Overhaul Interface	Optic	Hits raise fire rate; the bonus decays when you miss.

A	V11 Punch	Pistol	Thermal Surge Battery	Magazine	Charged shots track toward hostiles and overheat them.
A	Bully SMG	SMG	Rodeo Mag	Magazine	Fire rate climbs sharply the longer you hold the trigger.
A	KKV-9SD	SMG	Flechette Drum	Magazine	Breaking a shield triggers strong healing, stronger when you are alone.
A	V22 Volt Thrower	SMG	Overcharge Lens	Barrel	Consecutive hits detonate an explosive burst on the target.
A	Longshot	Sniper	Kingmaker Mag	Magazine	Headshots raise fire rate, stacking 3 times.

B	V66 Lookout	Precision Rifle	Sonar Shot	Barrel	Precision downs fire a sonar pulse that reveals nearby hostiles.
B	Magnum MC	Pistol	Pistol Scope	Optic	Adds a high-zoom optic; precision hits restore shields.
B	Misriah 2442	Shotgun	Full-Auto Selector	Grip	Fires full auto from the hip, with wider pellet spread.
B	V99 Channel Rifle	Sniper	Charge-Coupled Optic	Optic	Charge rate rises while you hold the target in the scope.
A	V00 Zeus RG	Railgun	Overclocked Generator	Generator	Doubles magazine size, so the double-shot costs no extra trigger pulls.

The V00 Zeus RG Overclocked Generator is worth singling out. Community lists still print it as stats-only. Bungie's Update 1.0.6 notes say it doubles the magazine, specifically so the railgun's double-shot stops costing a trigger pull and split shots on odd magazine sizes go away. On a gun whose base magazine is 5 and whose ceiling is 15, that is among the largest single-mod swings on this board. If a mod list tells you this perk is filler, it is reading a table that never got updated.

Do not own the gun yet? The base weapon has to come before the gold mod. A Prestige mod with nothing to sit on is 24,000 credits of decoration. PROs farm the base weapons themselves by class and rarity if the drop will not come.

Chips are the odd family, and the odd thing about them is what they are missing. Counting the current pool by rarity:

Chips are the only mod family with no Prestige tier, and simultaneously the deepest Superior pool in the game: 46 entries, more than double any other family's best tier. Both facts point the same way: for chips, Superior is the ceiling, so there is nothing to save for. The instinct that serves you everywhere else, hold your credits, wait for gold, is simply wrong here.

Chips are also the only mods that move freely between weapons, which makes them the best credit-per-hour purchase in the game for anyone still settling on a main.

Superior chips worth naming, with what they actually do:

• Bounty Hunter: 100 credits per UESC kill at Superior. Update 1.1.0 raised this tier from 25 to 100, a 4× buff that quietly turned a throwaway chip into the best credit farm in the pool. If you are grinding toward a 24,000-credit Prestige mod, this is how you pay for it.
• Rorschach Test. Reloading while surrounded overflows the magazine. 1.1.0 raised the ballistic overflow by roughly 20%.
• Circuit Tracers. Eliminations reload a massive portion of the magazine. The closest thing to never reloading in a horde fight.
• See Ya. Reloading on an empty magazine turns you briefly invisible. 1.1.0 took the duration from 3 seconds to 4, which is the difference between a panic button and an escape.
• Alternating Current. Restores a massive amount of health or shields when you damage an EMP'd target. Needs a build around it. Pays enormously when you have that chip equipped.
• Exterminator and Punishment. Flat large damage bonuses against Anomalous and Sph't combatants respectively. Swap by zone rather than carrying a single chip all season.
• Slip Protocol. Stability and accuracy while moving, by a massive amount. The honest pick for anyone who cannot hold still in a firefight.

Treat Mini Jammer with more caution than its reputation suggests. 1.1.0 added passive aim-assist and ADS-speed penalties across all tiers and slowed its activation, with the Superior tier going from 0.5 seconds to 1.0 seconds. It still works. It is no longer free.

Chips drop across every zone rather than from a single farm, which makes them a time problem more than a skill problem. The usual reason people ask us to run the chip farm instead of grinding it.

There is a way to get Prestige mods without paying 24,000 credits for them, and it happens to be the mode most Marathon players are already trying to run.

The Cryo Archive, aboard the abandoned UESC Marathon, contains 6 Vaults. Each Vault holds a Prestige-tier Unique weapon, and several of those weapons ship with a Prestige mod already installed:

Vault	Unique weapon	Base weapon	Prestige mod pre-installed
Vault 1	DRRVISH	BRRT SMG	Flechette Split Action
Vault 2	V99 WATCHTOWER	V99 Channel Rifle	Charge-Coupled Optic
Vault 3	SALT WAGES	Conquest LMG	Infinity Belt
Vault 4	V85 FREE-TAIL	V85 Circuit Breaker	none
Vault 5	M77 OMNIPOSITOR	M77 Assault Rifle	none
Vault 6	FIST OF PHOBOS	Stryder M1T	none

The catch is real and most people find it the hard way: Unique weapons have locked mod slots. The Unique rarity description is blunt about it. "This weapon uses unique upgrades; its mod slots are locked." So DRRVISH is a BRRT SMG that permanently has Flechette Split Action and a Superior Shortwave Scout Optic, and that is the gun forever. You cannot harvest the gold mod off it and you cannot tune the rest of the build.

That makes it a genuine trade rather than a free win:

• Take the Vault weapon if the pre-installed package is close to what you would have built anyway. You skip 24,000 credits and a Superior optic on top.
• Buy the Prestige mod separately if you care about the other slots. A base BRRT SMG with Flechette Split Action plus chips of your choosing beats a locked DRRVISH for anyone with a specific build in mind.

Timing matters more than most loot in this game. The Cryo Archive is not always open, and published schedules go stale fast. Many pages still print a fixed window, Thursday 10:00 AM PT to Sunday 10:00 AM PT, every week. Bungie has since changed the rotation specifically so that Cryo Archive and Ranked no longer run at the same time, after players complained about having to choose between them on a single weekend's worth of good gear. The current pattern is that Cryo drifts a day earlier each week while Ranked drifts later, overlapping only occasionally near a wipe. The fixed Thursday-to-Sunday answer is therefore stale. Check the in-game timer before you plan a session. It is the only source that is current by definition.

If the window keeps closing before you have a crew, PRO teams run Cryo Archive Vault clears while it is live, and the UESC Marathon raid around it, on your account.

Season 2 is live on 20 September 2026, and the mod sandbox it shipped with is not the one Season 1 players learned.

There is no thermal sniper optic in Season 2. Bungie rotated the Superior (Purple) SP Scope out of the loot pool, and since it was the last thermal sniper optic left, the category is simply gone for the season. If you are building a sniper around thermals, stop. You cannot finish the build.

Optics were rebalanced from spikes into spreads. The pattern across the whole optic family in Update 1.1.0 was to take a single huge stat and split it into 3 moderate ones. The Superior (Purple) Accu-Sight Optic went from +30 ADS Speed and +70 ADS Accuracy to +40 ADS Accuracy, +40 Range and +40 Moving Accuracy. The Superior Neuro-Optic Lens went from a flat +100 ADS Speed to +60 ADS Speed and +60 ADS Accuracy. Old optic recommendations built on the single-stat spikes no longer describe the items.

7 new chip perks arrived at once: Ghillie Suit, Buffer Overflow, Alarmist, Refocuser, Scrapyard and Exterminator across all rarities, plus Brain Freeze at Superior only. That is a meaningful share of the 46-chip Superior pool being less than a season old, which is the main reason chip advice written for Season 1 reads oddly now.

11 new Unique weapons landed in Update 1.1.0, including MACRO LS (a nimbler precision-rifle cut of the Longshot) and SIEGE ENGINE LMG (a Conquest LMG rebuilt as a mobile turret). Remember the locked-slot rule before you get attached to a Unique.

Where the game is right now: the live build is Update 1.1.5.2 from 28 July 2026, following 1.1.5 on 16 July and 1.1.5.1 on 21 July. The Vault Breaker experimental PvE mode that ran inside the Cryo Archive from 21 July has finished its window and ended on 4 August. Season 3 begins on 22 September 2026. That date is also the sensible deadline on any Prestige purchase: a seasonal loot-pool rotation is exactly what removed the thermal sniper optics, and a mod you buy in September has a shorter runway than a mod you buy today. The same deadline applies to this season's Ranked rewards, which do not carry over.

If you are staring at a credit balance and want the short version, spend in this order.

1. Superior chips, always, before anything else. They cost 3,105, they move between weapons, they are the deepest pool in the game, and for chips there is no higher tier to save for. Start with Bounty Hunter. At 100 credits per UESC kill it partly funds everything after it.
2. Superior optics and mags for the gun you actually main. Same 3,105, and after the 1.1.0 rebalance the Superior tier of an optic is a genuine 3-stat upgrade rather than a single spike.
3. 1 Prestige mod, only for a weapon you have kept for a full season, and only if it sits in the S band above. Paying 24,000 credits for a perk that adds stats you already have is the most common way people waste a week of extraction.
4. Cryo Archive Vault weapons whenever the window is open, treating a locked build you like as better than a perfect build you have not funded.

And the thing not to do: do not carry Prestige mods around as portable wealth. At 1,620 credits of exfil value against a 24,000 credit price, a gold mod in your bag is the worst risk-to-reward item you can be holding when a squad pushes your exfil.

Short on the credits to start any of this? Credits, faction rep and levels all come off the same extraction loop. The Marathon hub covers the grind under every item on this page.

A 24,000-credit Prestige is 8 Superior chips at 3,105 each, with a little left over. If you have not yet settled on a main, those 8 chips move with you when you swap guns. The gold mod stays on the gun you bought it for. That is why the buy order above starts at Superior chips and only climbs to Prestige after you have kept the same weapon for a full season. Cryo Archive is the exception: a Vault Unique arrives with the gold perk already bolted on, so you spend the window instead of the credits. Check the in-game timer the night you plan to run it.
