Marathon Factions: Which to Level and in What Order

Six Corporations and One Big Question: Where to Spend Your Time

Marathon has six factions: CyberAcme, NuCaloric, Traxus, MIDA, Arachne and Sekiguchi Genetics. Each one offers its own upgrades, vendors and rank rewards. All six are required for Cryo Archive access, so you will end up working on every one eventually, but the order you pick decides how smooth your first weeks feel.

This breakdown reflects the game after the Season 2 update and the October 6 Nightfall Refresh, which changed the system a lot. Core Runner stats moved out of faction trees into the Cradle, reputation comes faster, and rank requirements were lowered. Factions now handle gear, implants, kits and utility rather than raw health or damage boosts.

The trees reset every season, while access to factions you have already unlocked stays. That rewards players who grab what suits their playstyle first instead of trying to buy everything at once.

How Reputation Works and What Speeds It Up

Reputation comes from contracts and from extracting with items that belong to the faction. Since Season 2, standard contracts give much more rep, and the first five contracts each week add a flat bonus. The October refresh lowered rank thresholds for every faction on top of that.

Priority Contracts are no longer gated behind reputation. They focus on loot and optional objectives, so they are not the main way to climb ranks. The best weekly routine is simple: accept contracts for the factions you are leveling before a run, then extract with their valuables. Our Contracts service covers that grind, and Coaching helps if you want to learn efficient routes yourself.

Each faction has its own extra rep sources, and they usually match what you already do in a raid: opening crates, cracking caches, joining events. Details for each corporation follow.

CyberAcme and NuCaloric: Convenience and Survival

CyberAcme is the easiest faction to start with. Rep comes from runs, extractions, activating TADs, the Intercept event and extracting with CyberAcme valuables. Its tree is the most expensive: roughly 200,000 credits in full, a figure that may shift from season to season.

The tree includes vault space (Expansion), Carrier and Carrier+ backpacks, Informant.exe, Scavenger.exe, Heat Sink.exe for the Heat gauge, and Locksmith for keys. For a newcomer it is the clearest first step: more room, less heat, better looting.

NuCaloric covers consumables and protection. Expect free daily shields and healing, shielded implants, Recovery.exe and Self-Revive. The full tree costs about 85,000 credits. Rep comes from med cabinets, Tick nests, plants, supply drops and NuCaloric valuables. If you struggle to stay alive after firefights, start here.

Traxus and MIDA: Weapons and Gear

Traxus sells weapons and chip mods. Its tree has an enhanced Heavy SMG, the MIPS Longshot sniper rifle, attachments and late Deluxe weapons with Superior mods. The full tree runs about 62,750 credits. Rep comes from arms lockers, munitions crates, and the Convoy and Lockdown events.

It suits players who want a reliable arsenal. For a look at the guns themselves, check the separate weapons ranking; here it is enough to say that Traxus gets you to them sooner.

MIDA leans on explosives and tactical equipment. Its tree holds Flex Matrix.exe, Sprinter, Graceful and Survivor implants, claymores, trap packs, proximity sensors, ammo crates, grenades, anti-virus tools and Bubble Shields. It is the cheapest faction at around 59,250 credits. Rep comes from lockboxes, munitions crates, caches and Secured Resource events.

MIDA's final Capstone changed in Season 2: it now grants Anti-Virus protection for the first two minutes of a run and replaces the old Cardio Kick.

Arachne and Sekiguchi Genetics: Combat and Cores

Arachne is built for players who do not mind meeting other Runners. Rep comes from looting Runners, precision downs and finishers. The tree includes Hard Strike.exe, Cutthroat.exe, Reboot.exe, the MIPS Shotgun (WSTR Combat Shotgun) and mods for LMGs, railguns and shotguns. The full tree costs about 69,000 credits. In Season 2 some VIP nodes use Synapse Cubes instead of Prestige Salvage.

Sekiguchi Genetics is known for Cores. They are shell-specific, and each shell has two Core slots. The tree has shell-specific Core tracks, TAC_AMP.EXE, PRIME_AMP.EXE, HEAD_START.EXE, PRIMED.EXE, Harvester, Capacitors, SCAB_FACTORY.EXE and LETHAL_AMP.EXE, for about 71,500 credits. Rep comes from bioprinters, core storage, Anomalous Extraction and Targeted Treasure events.

Which shell pairs with which faction is a matter of taste. Players often suggest matching by style: NuCaloric healing to defensive shells, Traxus and Arachne to aggressive ones. Treat that as a hint, not a rule. The roster keeps growing too: besides Rook there is already Sentinel, and another shell is expected with the Symbiosis update.

Faction Comparison at a Glance

The prices below are approximate and may change with seasonal tuning.

Because of the price gap, the costly CyberAcme tree is better bought in pieces while credits are scarce. The cheaper MIDA and Traxus trees are easier to finish in full.

Where to Start: An Order for Each Playstyle

A solid default: a few high-value CyberAcme nodes for space and Heat, then NuCaloric for consumables, then the faction that matches your style. Careful players pair NuCaloric with MIDA, gun fans go Traxus, Runner hunters pick Arachne, and build crafters pick Sekiguchi Genetics.

Newcomers should remember the vault limit: while it is small, every extra item pushes out something you need. That is why the first CyberAcme nodes pay off faster than the rest, and later purchases are best aimed at a specific problem you notice in your runs: not enough healing, a weak weapon, no Cores.

Practical tips:

• Accept contracts for the factions you are leveling before the run, and extract with their valuables.

• Do not spend credits on everything: buy nodes that change your very next run.

• Save credits for the expensive CyberAcme nodes instead of spending them on small purchases that do little.

• If you would rather skip the routine, there is Power Leveling and Rent a Booster for squad runs, and season rewards are easy to collect through the Battle Pass.

Resets and Upcoming Dates

On October 6 the Nightfall Refresh (update 1.033) reset Runner, Cradle, faction levels, Priority Contracts, vault and credits. Access to factions you had already unlocked was kept. Rank requirements dropped for every faction, and VIP requirements now match the final standard rank.

Season 3 was pushed from September 22 to December 8 and will ship as the Symbiosis update. A new shell is expected with it.

For planning, that means one thing: do not count on fixed three-month seasons, so do not hold back purchases hoping for a long window. Buy what pays off right now.
