Marathon Factions Guide: All 6 Factions, Contracts & Progression
Marathon Factions: Complete Guide
Factions are the backbone of Marathon's progression system. Each of the six factions offers unique contracts, seasonal upgrades, and specialized gear that shapes how you play across an entire season. Understanding factions is essential — they determine your power floor, your gear access, and how quickly you recover from bad runs.
Seasonal Resets
All faction progress resets every season (~3 months). Gear, contracts, and faction rank all reset — only cosmetics, titles, achievements, and Codex progress carry over. Plan your faction investment around seasonal timelines.
How Factions Work
Unlocking Factions
When you start Marathon, only CyberAcme is unlocked. To access the other five:
- Complete the tutorial
- Finish the "Welcome to Tau Ceti" introductory contract
- Complete each faction's Liaison Contract to permanently unlock them for the season
Contracts
You can carry one active contract per deployment. Pick your objective before you queue, then complete it during your run. Extracting with an active contract also contributes reputation.
Three contract types operate within each faction:
| Type | Description | Rewards |
|---|---|---|
| Standard | Repeatable baseline tasks | Steady reputation, basic gear |
| Boosted | Harder, more specific objectives | Superior reputation, better gear |
| Priority | Non-repeatable missions that gate faction rank | Highest reputation, narrative progression |
Squad Strategy
If you're in a squad, commit to the same faction together. Most objectives are shared across the team, letting everyone progress simultaneously.
Multi-Faction Progression
Marathon does not lock you into a single faction. You can progress all six simultaneously without penalties. The system rewards mercenary-style flexibility rather than permanent loyalty.
Faction Breakdown & Priority Order
#1 — CyberAcme (Start Here)
Focus: Tech utility, economy, baseline optimization Agent: ONI Contract Theme: Balanced objectives — prime abilities, defeating hostiles, system interaction
CyberAcme is the recommended starting faction because its upgrades apply broadly across every playstyle. No build gets left behind by its progression tree.
Key Upgrades:
- Faster ability cooldowns
- Larger inventory and vault capacity
- Reduced heat (stamina) buildup
- Improved looting speed
- Better backpack options
Why First: Vault size and looting speed affect every single run, regardless of what shell you play. These are foundational upgrades that make everything else easier.
#2 — NuCaloric
Focus: Survivability, healing, movement, traversal Agent: Gaius Contract Theme: Biological collection, hacking repositories, biomass delivery, exploration
NuCaloric's reward track is built around keeping you alive longer. Consumables, salvage items, and implants define its progression.
Key Upgrades:
- More shield charges and patch kits
- Self-revive capability
- Status effect mitigation
- Improved self-repair speed
- Sprint duration and climbing improvements
- Free daily consumables from the armory
Why Second: Healing and survivability directly reduce how much gear you lose. Once CyberAcme gives you the economy foundation, NuCaloric keeps you alive to use it.
Free Daily Items
Once you unlock free daily items from NuCaloric (shield charges, patch kits), remember to claim them from the armory each reset. They don't auto-deposit.
#3 — Traxus
Focus: Salvage, weapon mods, high-value loot recovery Agent: Vulcan Contract Theme: Loot recovery, weapon/mod collection, container looting
Traxus is the gearhead's faction. Their progression offers the best weapon mods, chips, and access to high-tier weapons and defensive gear.
Key Upgrades:
- High-tier weapon access
- Advanced weapon mods and chips
- Defensive shields and armor
- Salvage efficiency bonuses
Why Third: Once your economy (CyberAcme) and survival (NuCaloric) are handled, Traxus lets you build stronger loadouts with better weapons and mods.
#4 — MIDA
Focus: Sabotage, explosives, area denial Agent: Gantry Contract Theme: Hacking, malware deployment, disruption of UESC infrastructure
MIDA's contracts put you in direct conflict with corporate systems. Their upgrades center on grenades, throwables, and area-denial tools.
Key Upgrades:
- Grenade and explosive access
- Area denial tools for chokepoints
- Movement speed bonuses
- Improved effectiveness against objectives
Why Fourth: Gadgets and grenades round out your toolkit nicely after your core upgrades are established from the first three factions.
#5 — Arachne
Focus: PvP combat, aggression, elimination contracts Agent: Charter Contract Theme: Direct confrontation — player eliminations, kill streaks, high-traffic zones
Arachne rewards the confident gunfighter. Their contracts emphasize PvP combat and their upgrades sharpen your killing power.
Key Upgrades:
- Combat-oriented stat boosts
- PvP weapon tuning
- Faster time-to-kill improvements
- Powerful weapon access (shotgun, railgun, LMG)
- Melee improvements
Why Fifth: PvP-focused upgrades are most valuable once you're already comfortable with Marathon's combat and have a strong gear foundation.
High Risk, High Reward
Arachne contracts put you in high-traffic PvP zones. Make sure you have solid gear and map knowledge before committing to this faction's contracts.
#6 — Sekiguchi Genetics
Focus: Shell enhancement, biomata technology, runner-specific cores Agent: Nona Contract Theme: Precision damage, implant extraction, Shell scanning, necrotic samples
Sekiguchi is the end-game faction. Their runner-specific cores fundamentally enhance shell abilities, but they require a solid foundation from other factions first.
Key Upgrades:
- Runner-specific cores for each shell
- Shell ability enhancements
- Biological stat boosts
- Recovery speed improvements
- Reduced early-death penalties
Why Last: Cores are the most powerful upgrades in Marathon, but they're meaningless if you can't afford to bring gear into raids or survive long enough to use them. Build your foundation first.
Progression Tips
- Grab Priority Contracts — They give 90 XP per objective (vs 60 for standard) and gate rank progression
- Re-roll bad contracts — If a standard contract has annoying objectives, re-roll and pick something else
- Hover for location hints — Contract objectives show exact location hints when you hover over them
- Extract to gain rep — Even failed contracts earn partial reputation if you manage to extract
- Track materials — Use the tracking system (hover + track keybind) to mark upgrade materials with a green eye icon in-game
- Always pick up universal materials — Diodes, biomass, gunmetals, gel, and lead are needed across all factions
All faction progress resets each season. Plan your investment wisely and focus on building a strong foundation with CyberAcme and NuCaloric before branching out.
