Marathon Season 2: Nightfall is estimated to end around December 8, 2026 (verified September 15, 2026). Season 2: Nightfall is Marathon's second season and its first full reset: Runner shell stats and faction reputation were wiped with the launch of The Cradle stat-customisation system. The season added the Night Marsh zone, the Sentinel Runner shell, faster faction levelling and a Duos rotating zone queue. On September 14, 2026 Bungie moved Marathon off a strict seasonal schedule, so there is no longer a fixed Season 2 end date: the next major chapter, Symbiosis, was pushed to December 8, 2026, with an interim Nightfall Refresh — a progression and economy reset plus a new Rewards Pass — on October 6. The $10 Battle Pass never expires, so unfinished cosmetics can still be unlocked later.
When Does Marathon Season 2: Nightfall End?
Marathon Season 2: Nightfall began on June 2, 2026 and no longer has a fixed end date. On September 14, 2026 Bungie moved Marathon off its strict seasonal schedule and delayed the next major chapter, so Nightfall now runs until Symbiosis arrives — currently estimated for December 8, 2026, the date this page counts down to until Bungie locks an exact timestamp.
Before then, an interim Nightfall Refresh lands October 6, 2026 with a full progression and economy reset and a new Rewards Pass. Symbiosis itself brings a Perimeter zone overhaul, a new Runner shell, and a permanent PvE experience.
How to Track the Season 2 End Date
Because Marathon dropped its fixed seasonal cadence, there is no confirmed wipe timestamp yet. This page's countdown tracks the estimated December 8, 2026 Symbiosis chapter and updates the moment Bungie confirms a date. Use the live timer to plan your Nightfall runs and Battle Pass tiers around the October 6 Rewards Pass reset.
Marathon Season History
Marathon is Bungie's sci-fi PvPvE extraction shooter, released March 5, 2026 on PC (Steam), PlayStation 5, and Xbox Series X|S with full cross-play and cross-save.
Season 1: Death Is the First Step ran from launch on March 5, 2026 to June 2, 2026 — 89 days — before Season 2: Nightfall began. Each season reset brings a full progression wipe alongside new content.
Marathon Battle Pass Cost and Value
The Marathon Battle Pass costs $10 per season. Bungie has confirmed Battle Passes never expire — players can purchase and unlock any previous season's pass at any time, removing the usual fear-of-missing-out pressure.
All Battle Pass content is cosmetic only. Marathon has no pay-to-win elements: every Runner, map, and weapon is free for all players regardless of Battle Pass purchase.
