Enter the dark science-fiction world of Tau Ceti IV, an abandoned colony where rival Runners, hostile UESC security forces and an unpredictable environment turn every deployment into a high-risk extraction. Marathon is built around tense runs where preparation, positioning and the decision to extract can matter as much as raw firepower.

  • Search dangerous zones for valuable gear alone or with a crew.
  • Face intense PvP encounters while managing limited resources.
  • Extract successfully to strengthen future loadouts, build seasonal power and earn cosmetic rewards.
