NIKKE 4th Anniversary: Two New Bosses and the End of the Ark Saga

Goddess of Victory: NIKKE is ending its biggest story arc yet with the 4th Anniversary update, and the Main Battle is the heart of it. This GameMarket.gg breakdown covers everything in the NIKKE 4th Anniversary main story, from the two climactic new chapters and their fearsome bosses to the TRAIL MARKER rewards you earn for clearing them. Launching on October 29, 2026, the update caps off the Underground Ark saga with a desperate "Final Battle" for the surface, and it hands out a mountain of free rewards for seeing it through. Here is the full rundown of the Main Battle, its bosses, and what you get for beating it.

The anniversary Main Battle at a glance

Here are the key points before the full breakdown:

• Release: October 29, 2026, on PC, iOS, and Android.
• New chapters: Main Chapters 49 and 50, closing out the Underground Ark storyline.
• Theme: the 3rd Surface Reclamation War, as the Ark rises and the Queen advances.
• New bosses: Nostalgia in Chapter 49 and the Goddess of Victory in Chapter 50.
• Clear event: TRAIL MARKER rewards you for finishing the main story during the anniversary.
• Tie-in: the Goddess of Victory boss also headlines Solo Raid Season 43.

Chapters 49 and 50, the Final Battle

The core of the update is two new main chapters that bring the long-running Ark arc to its climax. They unlock on October 29 once you have cleared Chapter 48, and they are built around the 3rd Surface Reclamation War, with the Ark finally rising to the surface as the Queen pushes to destroy it. After years of buildup, this is the payoff the story has been driving toward.

The chapter titles set the tone perfectly. Chapter 49 is called "Staking Everything," flagged in-game as the Final Battle, while Chapter 50 closes things out as "We Rise Above." That framing makes it clear this is not a routine story drop but the resolution of the Ark saga, so players invested in NIKKE's surprisingly deep narrative will want to play through both as the main event of the anniversary.

Because this is the finale of a major arc, it also raises the stakes for your roster. The new chapters come with tough encounters that test how well you have built your Nikkes, which is part of what makes the Main Battle feel like a genuine climax rather than a victory lap. It is the kind of story beat that rewards players who have kept up with the game, capping a busy stretch of updates that ran right up to the recent October Belorta Halloween update.

For anyone new to it, NIKKE is a free-to-play story-driven shooter RPG where you command a squad of characters called Nikkes against the robotic Raptures to reclaim the surface. What sets it apart from most gacha games is how seriously it takes its story, with fully voiced cutscenes and a plot that fans rate highly, so a main-story finale like this carries real weight for the community rather than being an afterthought between banners. That focus is exactly why the Main Battle, not the new units, is the headline of the anniversary.

The new bosses: Nostalgia and the Goddess of Victory

What makes the Main Battle memorable is its two new bosses, each tied directly to the story's emotional core. The first is Nostalgia, which debuts in Chapter 49 as a massive entity born from a twisted desire for paradise, connected to Dorothy's corruption. It is a fittingly tragic obstacle for a story about clinging to a lost world, and it sets the stage for the finale.

The true climax comes with the second boss. Chapter 50 pits you against the Goddess of Victory, the Queen who has stolen Liliweiss's body and fused with the Orbital Elevator, aiming to wipe out the Ark entirely. Facing a foe literally named the Goddess of Victory as the game's own title is a pointed, dramatic touch, and it makes the final chapter land as the showdown the whole arc has promised.

For players who want more of that fight, the Goddess of Victory does not stay confined to the campaign. The boss also headlines Solo Raid Season 43, giving the community a fresh endgame challenge to test their best teams against well after the story is done. That overlap between the Main Battle and the raid season means the anniversary's toughest content revolves around the same climactic villain, which keeps the whole update feeling connected.

Solo Raid is where NIKKE's hardcore players prove their roster, since it ranks you against the rest of your server based on how much damage you can pour into a single boss. Building a team specifically to melt the Goddess of Victory becomes its own long-term goal, and pairing that raid with the story finale gives the anniversary a satisfying one-two punch: beat the boss once in the campaign for the story, then grind it for leaderboard glory. For competitive players, that is reason enough to make sure their best Fire and anti-boss teams are ready before the season opens.

TRAIL MARKER rewards and the new anniversary units

Clearing the Main Battle is not just about the story, because the anniversary ties generous rewards to finishing it. The TRAIL MARKER event rewards you for clearing all the main chapters during the anniversary period, handing out Recruit Vouchers, Custom Modules, and more, while a separate 3rd Surface Reclamation War web event adds even more on top. Between the two, playing through the finale is one of the most rewarding things you can do this patch.

The anniversary also loads up on new units to take into that fight, led by two Fire-element attackers:

• Marian: Queen is a Burst III Fire Code Attacker with a Machine Gun, built for multi-target damage, with her Pick-Up running from October 29 to November 19.
• Scarlet: Godslayer is a Burst III Fire Code Attacker with an Assault Rifle who specializes in penetration and can shift between an armored form and a lighter, more agile form, with her Pick-Up from November 5 to 26.
• Rapunzel: Sanctuary is a free Burst II Fire Code Supporter with a Rocket Launcher who heals and buffs allies, and you can claim up to four copies through login and the MARIA-n event.

On top of those, the anniversary is extremely generous with free pulls. Players can earn more than 200 free recruitment attempts across the various events, plus 4th Anniversary Selection Boxes that let you pick a past SSR, so even free-to-play players have a real shot at the new units. It all adds up to a milestone patch that rewards both your time and your roster, continuing the steady stream of new SSRs seen in updates like the September 17 drop.

Should you jump in?

For existing NIKKE players, the 4th Anniversary Main Battle is essential, since it resolves the Underground Ark story, introduces two memorable bosses, and ties hundreds of rewards to clearing it. Even if you only care about the loot, the TRAIL MARKER and web events make playing the finale the most efficient way to stock up on Recruit Vouchers and materials this patch.

If you have drifted away or never played, a story-defining anniversary is one of the best moments to jump in. The game is free to play across PC and mobile, and the flood of free pulls plus a selectable SSR means a fresh or returning account can make huge progress fast while experiencing a major story climax as it happens. The Main Battle is designed to be the centerpiece everyone logs in for.

Either way, the 4th Anniversary Main Battle is a landmark moment for NIKKE, ending its biggest arc with a genuine final showdown. The smart move is to log in from October 29, push through Chapters 49 and 50 to face Nostalgia and the Goddess of Victory, and claim every TRAIL MARKER reward while the anniversary is live.
