All The First Descendant Seasons & Dates: Complete History

The First Descendant launched globally on July 2, 2024, and Nexon’s free-to-play looter shooter has shipped 6 seasonal updates since — beginning with Season 1: Invasion in August 2024 and running through the current Season 3, Episode 4: Dimensional Clash. The cadence has evolved sharply: Season 2 stretched across an unusually long 245-day window, then Season 3 broke into four shorter ~90–106 day “episode” drops. This is every The First Descendant season with verified dates, durations, and the stats most other lists miss.

How The First Descendant Seasons Work

The First Descendant runs on a two-tier seasonal model. A Season is the overarching narrative arc (Invasion, Void Chaser, the multi-part Season 3) that brings a new villain, a major systems update, and the season’s flagship Descendants. An Episode is a sub-drop inside a Season — Season 3 alone has shipped four episodes (Breakthrough, Assemble, Unveiled Truth, Dimensional Clash), each with its own Battle Pass cycle, new Ultimate Descendant, and themed activities.

Each episode includes a Premium Season Pass costing 500 Caliber (~$9.99 USD). The pass unlocks a tiered reward track of Legendary Descendant skins, weapon blueprints, cosmetics, and up to 300 Caliber refunded on completion. A free track runs alongside it. Unclaimed pass tiers expire the moment the next episode launches — Nexon does not offer a buy-back window.

What carries over between seasons: every Descendant unlocked, all owned weapons and modules, your Mastery Rank, claimed cosmetics, and any Caliber purchased. What resets: the Battle Pass track itself, seasonal challenge progress, and limited-time event currencies.

All The First Descendant Seasons: Complete Dates Table

Every The First Descendant season and episode in launch order, newest first. Dates are taken from Nexon’s official patch notes and the in-game season panel; durations are end-to-end day counts.

Season 1: Invasion (August – December 2024)

Season 1 launched on August 29, 2024, roughly two months after The First Descendant’s July 2 worldwide debut. Invasion ran for 98 days and introduced the first major post-launch villain arc, the Ultimate Descendant Ultimate Valby, the Hagios region expansion, and the Void Erosion Purge endgame activity. Nexon used this cycle to stabilise core systems and respond to early launch feedback — most notably the grind reductions that landed in the mid-season patch.

Season 2: Void Chaser (December 2024 – August 2025)

Season 2: Void Chaser is the longest cycle in The First Descendant’s history at 245 days — nearly two and a half times any other season. Launched December 5, 2024, it ran straight through to August 7, 2025 and bundled together what would become a sweeping rewrite of the game’s combat and progression. Highlights: the Karel storyline kickoff, Ultimate Descendant Hailey and Ultimate Keelan, the Inversion Reinforcement system, and the heavily reworked Void Intercept Battles. The extended runtime was Nexon’s deliberate response to player feedback about content burn-rate — but it also meant Season 2’s Battle Pass had the longest grind window in the game’s history.

Season 3 (August 2025 – ongoing) — the four-episode era

With Season 3, Nexon split the format entirely. Instead of one long arc, Season 3 is being delivered as four episodes, each roughly a quarter of a year long, each with its own Battle Pass and new Ultimate Descendant:

• Episode 1: Breakthrough (Aug 7 – Nov 6, 2025, 91 days) — kicked off the four-episode model with Ultimate Bunny and the first taste of the Karel-arc endgame.
• Episode 2: Assemble (Nov 6, 2025 – Feb 5, 2026, 91 days) — introduced Ultimate Sharen and expanded the Mastery Lab.
• Episode 3: Unveiled Truth (Feb 5 – May 21, 2026, 106 days) — slightly extended; shipped the Onslaught Mode beta in April 2026 and Ultimate Lepic.
• Episode 4: Dimensional Clash (May 21, 2026 – open) — the full Onslaught Mode launch, Ultimate Esiemo (Black Detonator), two new Ultimate Weapons, and a complete Farming Loop overhaul. It’s the final episode before Season 4’s climactic showdown with Karel; the current The First Descendant season timer tracks its close.

Season Duration Analysis

Longest and shortest seasons

Season 2’s 245-day run wasn’t a mistake — Nexon publicly acknowledged that early post-launch content was being burned through faster than they could ship the next major arc. The Void Chaser window was extended to give the studio room to retool the Karel storyline, rebuild progression systems, and stand up the episodic format that Season 3 now uses. Strip Void Chaser out and the average season duration across the remaining five entries is 95.4 days — almost exactly a quarter.

Average season length

Across all five completed seasons, the mean is ~126 days. Strip out the Season 2 outlier and the figure drops to roughly 95 days — confirming the modern target of a roughly three-month episodic cadence.

Are The First Descendant seasons getting shorter?

Yes, by design. The shift from monolithic seasons (S1, S2) to the four-episode Season 3 model deliberately tightened cadence from “one major drop every 6–8 months” to “one new Ultimate Descendant + Battle Pass every quarter.” More frequent meta refreshes, smaller per-drop content packages, and a Battle Pass cycle that aligns with seasonal grind tolerance.

What remains uncertain: whether Season 4 continues the episodic model or returns to a longer single-arc structure. Nexon has announced Season 4 with a Mega Dungeon, a complete weapon system overhaul, and Transcendent-tier weapons; exact timing is tracked on the current The First Descendant season timer.
