Moonlighter 2: The Endless Vault Moonlighter 2 Achievement Guide

Moonlighter 2: The Endless Vault has 56 Steam achievements on app 2350790. This page is the fastest route to 100% — not a spoiler dump of every hidden description, but a map of the conditions, the order to unlock them, and which ones can slip through a careless run. Version 1.0 (2 September 2026) is the build this guide assumes.

The game is single-player. There are no redeem codes that pop a trophy. Consoles (PlayStation 5, Xbox Series, Nintendo Switch 2) use the same job list under their own trophy chrome; counts may differ slightly by platform.

Achievement structure

Steam groups achievements into clusters by system:

• Shop cluster — open the shop, stamp Perfect, fill the Perkmeter, upgrade the floor, seat a Bloblet, and equip furniture.
• Vault cluster — lifetime gold gates I through V, then the 300,000 single-day challenge at Vault VII, then Infinite Vault repeats.
• Combat cluster — Rupture smashes, gun kills, biome clears, Colosseum waves, Boss Rush aspects.
• Collection cluster — Codex pages, Deluxe relics from Tomo, Julien patches, Endless cosmetics.
• Story cluster — first sale, town progress, named cutscene flags, and the 1.0 ending.

100% Moonlighter 2

First weekend: the easy cluster

These pop on a normal first playthrough if you follow the getting started and walkthrough:

1. Back to Business — complete your first shop sale in Tresna.
2. Back on Track — early story progress after the Ms Scratch tutorial.
3. Wishing Well — the cube speaks for the first time at 10,000 lifetime gold.
4. Just Like Old Times — callback to the 2018 loop; earned in Kalina.
5. An Unwelcome Guest, Forced Shutdown, Dismissal Letter, Overture — combat and story flags as you clear biomes. Names match dungeon energy.

Do not hunt these. Play the biomes in story order and they land.

Vault cluster in order

The Vault gates are the slowest achievements if you do not plan them:

• Vault I (10,000 lifetime gold) — opens The Gallery. The cube erupts on your first honest shop week.
• Vault II (50,000) — opens Aeolia, the first shop upgrade, and Hex as a dungeon path.
• Vault III (120,000) — Luminous Pendant, tier 2 patches, Weapon Mastery task.
• Vault IV (200,000) — Burning Hammer and Ultimate melee recipes.
• Vault V (500,000) — Greed Colosseum access and the fifth narrative key.
• Vault VII (300,000 in one day) — dedicated morning, full bag, Perfect Stamps only until the Perkmeter is full.

Lifetime means earned across the save, not held. The cube stops counting a challenge the moment you hit the number. Do not slam a 2,000-stamp Legendary into Vault I when you are 2,000 short — bank it for II.

Combat achievements that are easy to miss

• Rupture smashes — several shields only drop when you backpack-smash a ruptured object into the boss, not when you empty an HP bar. Read bosses before you assume a fight is a pure DPS check.
• Gun kills — flyers (Thalaam, air phases) need the gun. Keep Blo-Beam on the second slot.
• Colosseum waves — Greed Colosseum unlocks at Vault V (500,000). Fail it and relic quality halves. Run it when Ultimates are on, not as your first combat exam.
• Boss Rush aspects — Blob-Life added Boss Rush with weapon aspects as rewards. Use it to practice without a full relic bag.

Hidden achievements

Steam hides two names:

• Out of Tune — tied to Kalina Night and a music reference. Play the night biome; do not open this page looking for a trigger.
• The Fallen King — tied to the Aeolia king fights (Senda and Monte). Finish both mask paths; this wiki will not print the unlock text.

Both are story-adjacent. They pop when you clear the relevant content.

Shop achievements and how they stack

• Stamp Perfect — the red stamp face. This is the most common unlock condition across the shop cluster. Shop prices: Silence Shell 21, Sand Fruit 31, Firewood 42.
• Fill the Perkmeter — sell cheap and Perfect tags until the bar is full. Expensive tags do not fill it.
• Seat a Bloblet — Blob-Life (May 2026) added companion pets. Rescue them from dungeons, then seat one on the shop floor. Shop rank 4 and 5 added extra Bloblet slots in 1.0.
• Equip furniture — The Countess sells furniture. Any piece counts. Deluxe Zen Patio DLC counts the same as Countess inventory.

Missable conditions

• Boss trophies — Herald (Sound of Hubris), Thalaam (Alabaster Candle), Curator (Quantum Core), Tyke (Broken Rocket), Senda (King’s Left Mask), Monte (King’s Right Mask). Dropping a material does not prevent the achievement, but it requires a replay of that boss.
• Hardcore — the 1.0 death rule restarts the save on dungeon death. Do not flip it on a file you are using to mop trophies.
• Mode-locked achievements — Hardcore Adventurer and Endless are fixed at save creation. If you started in Adventurer, you cannot earn a Hardcore Adventurer trophy on that file.
• Weapon mastery — stick to one melee class instead of swapping every run. The builds and weapons lists exist so you can finish one identity.

Platform notes

Steam Cloud is on for app 2350790. PlayStation 5, Xbox Series, and Nintendo Switch 2 launched with 1.0 the same day; Game Pass is the same build. None of them add multiplayer achievements, because there is no multiplayer.

If you bought Deluxe, you still earn the same 56. Zen Patio furniture is cosmetic. The $20.99 launch sale (30% off $29.99 through 16 September 2026) is the same full game.

Soundtrack is Christopher Larkin. Demo progress does not transfer to the main save.

When you are done mopping, return to the Tools Hub. The rest of the wiki assumes you would rather stamp a Brood Charm than stare at a locked icon.
