Splatoon Raiders Post-Game Guide

When post-game begins

Splatoon Raiders post-game opens after the Good Ending credits roll on Nintendo Switch 2. The Good Ending requires defeating Salmonarch in the Great Salmon Mess Hall Throne Room while collecting enough Power Eggs during the fight—see How to Beat Salmonarch for phase tips and How to Unlock Endings for the full Good vs Bad fork.

Only the Good Ending triggers the post-credits scene. That sequence is your bridge into true endgame: hints toward Hidden Ruins and the relic hunt that eventually unlocks Bottomless Buffet. Do not skip post-credits if you care about narrative payoffs.

The Bad Ending fires when Power Egg collection fails during the same Salmonarch encounter. It does not permanently block post-game geography—Atke, Suma, and Kinp still appear once the campaign flag completes—but you miss the immediate post-credits beat until you Good-clear or replay the Throne Room with a successful egg run.

You keep your Mechanic, Hideout Ship upgrades, Bot Buddy Bond progress, and inventory throughout. Early islands Lehlo and Erpp remain on the Spirhalite chart; post-game adds three more rotation targets alongside fresh dungeon tiers and the long-form Bottomless Buffet gauntlet.

New islands: Atke, Suma, and Kinp

Each post-game island reuses the raid grammar you learned on Lehlo and Erpp—Past Adventures markers, Treasure Hunt greed, Shard Mining, gem search, Sampler compass reveals—but pushes Salmonid density and objective timers harder. Treat the trio as a rotation, not a linear checklist:

• Atke — Home to Fischflak (~Lv42); strong shard and material density for mid-post-game Builds.
• Suma — Hosts Myunyere (~Lv46); mixed relic and scroll routes; pair with Briny Scrolls hunting when orange crates appear in Treasure Hunt nodes.
• Kinp — Contains Smoksam (~Lv44); higher Seasoned Salmonid presence; confirm tank Skill Tomes before Spicy attempts.

Use the Walkthrough Hub and dungeons guide to match each island icon to the resource you actually need tonight.

Hidden Ruins: Fischflak, Smoksam, and Myunyere

Post-game exposes Hidden Ruins—secretive Buried Ruins-style stages tied to specific islands:

Island	Hidden Ruin	Approx. level
Atke	Fischflak	~Lv42
Kinp	Smoksam	~Lv44
Suma	Myunyere	~Lv46

These are not casual sightseeing runs. They test shield breaks, vertical Bot Buddy hops, and relic-aware loadouts under tighter timers than early Erpp content. Each clear awards a Salmonid Relic tied to the tank archetype you brought—Power, Speed, or Tactical identity matters.

Approach them with intent:

1. Pick the tank whose relic identity you want reinforced.
2. Pre-slot gadgets that solve that ruin’s telegraph (shields, swarms, or kiting lanes).
3. Bank Mega Power Eggs for Boss Salmonid rooms instead of opening with Showstoppers.
4. Review Big Man’s Hoard after each clear so new relic powers get equipped.

Bottomless Buffet stays locked until you finish every Hidden Ruin once per tank archetype—that is three ruins × three tanks = nine relics total. Track completions on the Raid Checklist so no tank slot is forgotten.

If a Hidden Ruin feels impossible, drop to Tourist or Raider difficulty. Tourist, Raider, and Survivalist change enemy strength only—loot does not change with difficulty. Farm Bond via How to Increase Bot Buddy Bond until Showstoppers carry the boss phase.

All three tanks in endgame

Post-game is where Power, Speed, and Tactical tanks stop being “the one you liked in chapter two” and become specialized tools—and mandatory keys for Buffet unlock:

• Power Tank — Center mass breaks, shield-heavy Boss Salmonids, and rooms that reward staying planted.
• Speed Tank — Mobile Lesser packs, timed gem search lanes, and fights that punish slow repositioning.
• Tactical Tank — Chokepoints, deployable coverage, and co-op lanes where gadgets create safe objective windows.

Skill Tomes from Sampler Dungeons remain the honest gate for tank depth. Cross-check finished kits on the Builds hub and Tier List when you swap tanks between islands. Relic details live on Relics.

Bottomless Buffet unlock and purpose

The Bottomless Buffet is the headline post-game activity—a Survivalist-locked gauntlet that stress-tests your best loadout, Bot Buddy timing, and resource discipline. It unlocks only after clearing Fischflak, Smoksam, and Myunyere with all three tank archetypes for nine relics total.

Once unlocked, rules differ sharply from normal raids:

• Survivalist only — Tourist and Raider cannot enter.
• No Call for Help — You must sustain pushes solo or with co-op partners who also meet Survivalist requirements (How to Play Co-op).
• Three floors at a time — Each sortie advances a chunk of the tower starting near Level 50 Salmonids.
• Floor 100 — Lord Saltimatum spawns the secret ending cutscene, distinct from Salmonarch’s Good/Bad fork.
• Continues after 100 — The mode keeps going if you choose; the narrative secret ending fires at Floor 100.

Cosmetic hunters should note Golden Flash, Golden Fever, and Golden Forever outfit unlocks at floors 30, 60, and 100 respectively. For step-by-step unlock conditions, route tips, and Endless Search relic rewards, read How to Complete Bottomless Buffet.

Salmonarch recap and boss gates

Post-game islands still rotate Boss Salmonids, and Salmonarch remains the campaign’s major ending gate. If you Bad-cleared first, replay the Throne Room when ready—both endings live on one save file. Pivot to How to Beat Salmonarch before spreading shards across three islands at once if you still need the Good Ending post-credits.

Collectibles and Hoard completion

Post-game is the natural window for Briny Scroll completion (~56 scrolls for the Spirhalite Gem milestone), Old Compass Sampler reveals, and amiibo outfit flex. Track scroll registration in Big Man’s Hoard via the Hideout; details live on Briny Scrolls and the broader Collectibles page.

Orange crates in Treasure Hunt dungeons on Suma and Kinp are high-yield scroll nights. Finish the win condition first, then crate-scout—same rule as early Erpp, just with meaner Seasoned adds.

Suggested post-game session loop

1. Good-clear Salmonarch if you have not seen post-credits yet.
2. Pick one island (Atke, Suma, or Kinp) and one goal: shards, scrolls, relics, or Skill Tomes.
3. Queue the matching dungeon type from the Walkthrough matrix—not whatever icon is closest.
4. Attempt one Hidden Ruin with a deliberate tank swap; tick off the nine-relic checklist.
5. Unlock Bottomless Buffet, then push three-floor bands toward floors 30, 60, and 100.

Co-op still works online and via local wireless on Ver 1.1.0 (July 22, 2026) or later—that patch adjusted music, fixed bugs, and is required for online play with matched versions for local or LAN sessions. It is not a content drop. Patch details sit on the Patch Notes Hub.

What post-game is not

It is not a separate save file, not a New Game Plus reset, and not a place where amiibo scans suddenly become mandatory. It is where Splatoon Raiders expects you to rotate tanks, finish Deep Cut Bond, clear nine Hidden Ruins relics, and chase the Buffet climax. Start on Atke for economy, graduate to Hidden Ruins for mastery, and use Bottomless Buffet as the scoreboard.
