UESC Marathon — Tau Ceti IV — 2893
A century after the UESC Marathon and its colony vanished without a trace on Tau Ceti IV, bio-cybernetic Runners now scavenge the deadly ruins for artifacts, data, and survival. You are one of those runners.

View Intel →Update 1.1.0 added Streamer Mode, daily Duos queues, matchmaking countdowns, network preference options, improved new-player matchmaking, a single merged Ranked mode, larger overflow inventory, higher contract faction reputation, earlier Sponsored Kit unlocks, Cradle-era balance changes, and many fixes across movement, Runner abilities, economy, UI, zones, and stability.
Season 2 is live with Night Marsh, the Sentinel defensive Runner shell, the Cradle progression system, KKV-9SD, D54 Battle Pistol, new enemies, new rewards, combat sandbox changes, faster progression, and the Sponsored Survival experimental queue. Cryo Archive returns June 11, Ranked returns June 14, and more experimental queues are planned later in the season.
Marathon's full game is free to try from June 2 through June 9 across Steam, PS5, and Xbox Series X/S. Progress and earned items carry over for players who purchase after the event. The week also introduces Sponsored Survival, a PVP-lite Night Marsh experiment with one crew, backfilled Rooks, Sponsored Kit loadouts, an 18-minute timer, and a final exfil truce-or-betrayal decision.
Bungie closed Season 1 with community recap stats and Runner Level reward tiers. Players receive CyberAcme Sponsored Kits in Season 2 based on levels 10, 25, 50, and 75, with higher tiers earning all lower rewards too. Bungie also reiterated that Season 2 starts June 2 with Night Marsh, Sentinel, the Cradle, updated contracts, and Open Play Week.
Bungie previewed Season 2 sandbox changes across weapons, mods, chips, progression, and Runner builds. The goal is to make the new Cradle system and Night Marsh gear matter without letting Season 1's strongest breakpoints dominate the next reset.
