Complete Guide to Marathon Factions

Introduction

Welcome to our Marathon Complete Factions Guide, where we break down each faction’s objectives, reputation progression, and reward tiers to help you advance efficiently across Tau Ceti IV. Learn how to optimize your loadout, choose the right contracts, and plan smart extraction routes to complete faction tasks quickly while maximizing reputation and rewards.

What are Factions?

In Marathon, factions form the core of long-term progression, acting as a voluntary, reputation-driven system that allows Runners to align with powerful organizations operating across Tau Ceti IV.

Instead of mandatory wipes or forced resets common in other extraction shooters, Marathon’s faction system lets you choose who to work for, which contracts to pursue, and how to shape your progression through deliberate decisions and successful extractions.

There are a total of 6 factions in the game, and they are as follows:

• Arachne
• CyberAcme
• MIDA
• Nucaloric
• Sekiguchi
• Traxus

Each faction represents a distinct ideology, playstyle focus, and reward path, offering unique gear, upgrades, and long-term benefits. Your relationship with these factions evolves entirely through your actions in the field, making faction progression a strategic choice rather than an obligation.

Now that we named each of them, we will talk more in detail about each one so you know what faction you should rank up.

Arachne

Arachne is a death cult, and as you might expect from people who are obsessed with death, they want you to kill other Runners. It's unclear what rewards Arachne offers for completing contracts. If we had to guess, the rewards will most likely aid you in taking down enemy Runners.

CyberAcme

CyberAcme is responsible for the systems that allow people to upload their consciousness into shells. By extracting valuable materials from Tau Ceti, CyberAcme will upgrade your Shell, making you more durable than ever before.

MIDA

MIDA is one of the factions featured in the original Marathon trilogy, so we know considerably more about its motives. In the previous games, MIDA was a political party that transformed into a terrorist organization after years of feuding with the UESC. As explosive experts, MIDA is obsessed with blowing things up, and its contracts revolve around destroying things.

Nucaloric

Nucaloric is represented by Gaius: a plain, pink, expressionless head with a well-spoken voice. Gaius explains in-game that the company exists to "feed, clothe, and supply humanity with its most basic needs." As major stakeholders in the colony, the contracts offered by Nucaloric require you to learn why the original Marathon expedition failed over a century ago.

Sekiguchi

Sekiguchi is similar to CybeAcme; it's responsible for the Weaveform technology used to create the shell bodies worn by Runners. We don't know Sekiguchi's intentions as the faction is brand new to the Marathon universe. In the Visions of Marathon video, the Sekiguchi representative is Nona, a white, winged insect with red eyes and several arms.

Traxus

As the richest and most powerful faction in Marathon, Traxus uses its money to influence Tau Ceti from the shadows. Traxus makes its money by focusing on resource extraction, with various contracts in the alpha tests asking players to disrupt the UESC's supply chain. Traxus' contracts will primarily ask you to find specific weapons and weapon mods.

That's everything we know about the factions in Marathon, but stay tuned as we'll be updating this guide when new information drops.

Conclusion

Faction progression represents one of the most meaningful long-term systems in Marathon, rewarding deliberate planning, consistent execution, and smart decision-making across multiple runs. Your relationship with each faction is built over time through completed contracts, successful extractions, and efficient risk management, directly shaping the gear, upgrades, and advantages available to you as a Runner.

Success with factions comes down to intent and preparation. Choosing which faction to prioritize, understanding their reward paths, and aligning your loadouts and routes with specific objectives will define how impactful your progression becomes. When approached correctly, faction progression turns every run into a strategic investment, transforming short-term risk into long-term power for Runners who think ahead and play with purpose.
