Arachne: Faction Guide

Arachne is a bio-technology and surveillance corporation operating on Tau Ceti IV with a focus on distributed sensor networks, synthetic biology, and micro-drone systems. Named for their signature web-like surveillance infrastructure, Arachne's reach extends to virtually every corner of the Promised Land, they see everything, hear everything, and sell the data to the highest bidder.

Overview

  • Specialty: Surveillance drones, synthetic biology, sensor network infrastructure
  • Playstyle alignment: Recon specialists, Locus Shell users, scout-and-extract runners
  • Primary rivals: CyberAcme (cybernetics market), MIDA (military contracts)
  • Zone presence: Strong in Perimeter (outskirts) and throughout tunnel networks in Terminus

Lore & Background

Arachne established the first comprehensive sensor grid on Tau Ceti IV before any other corporation had boots on the ground. This surveillance advantage gave them an outsized role in the colony's early development and made them indispensable to every faction, even rivals buy Arachne intelligence feeds when they can't afford to be blind.

When UESC AI began going rogue across the Promised Land, Arachne's drones became the primary early-warning system for Runner deployments. Their synthetic biology division has also been quietly working on bio-augmentation that merges organic tissue with drone-like sensor arrays, a technology that could blur the line between Runner and machine.

Contracts & Missions

  • Node Repair: restore damaged Arachne sensor nodes that UESC constructs have disabled
  • Blacksite Recon: mark and photograph enemy installations without being detected
  • Drone Recovery: retrieve downed Arachne micro-drones from hostile-controlled areas
  • Bio-sample Collection: gather biological specimens from UESC constructs for Arachne's research labs

Reputation Tiers & Rewards

  • Tier 1: Observer: Motion sensor tools, basic recon drone deployable
  • Tier 2: Scout: Advanced recon drones with combat feeds, enhanced Locus Shell passive bonuses
  • Tier 3: Operative: Arachne web-trap deployables, enemy-tagging micro-drones, stealth detection tools
  • Tier 4: Handler: Full-map passive surveillance feed during deployment, Locus Shell exclusive augments

Strategy Tips

  • Arachne contracts are among the safest to run, many can be completed without engaging enemies directly
  • Tier 4 map surveillance feed is arguably the strongest quality-of-life reward in the game, a top-priority investment
  • Pair Arachne recon contracts with the Void Shell for near-undetectable survey runs
  • Arachne's sensor nodes often mark nearby loot caches, fix a node and check surroundings before moving on
