How Songs Unlock in In Falsus, Frame by Frame

• ▸Songs arrive through the story: encounters introduce them, and the "Timeline Unlocked" dialog marks where replayable story entries begin.
• ▸Every song carries a difficulty ladder — Latent Duality shows 4 / 7 / 11, With Truth shows 1 / 4 / 8 / 10 — and a cleared chart can extend it.
• ▸Clearing the song and winning the encounter are separate: a DIVE CLEARED rank A can still end in ENCOUNTER FAILED when the card loadout is too weak.
• ▸FORBIDDEN opens the same way: after a clear, a "New Difficulty Unlocked" banner announces that songs can now be challenged on FORBIDDEN LV 11.

Every frame in this guide comes from one video: Flaw D.’s launch-day walkthrough “In Falsus Is out today! Unlocking all songs”, recorded on the full game the day after release. Each figure deep-links to the exact second it was taken from. The streamer’s facecam has been cropped out of every export.

Fact discipline: where the footage does not show a rule, we say so instead of guessing. A widely shared first-impressions video of the demo’s five-song library circulates alongside full-game clips — it predates the September 9 release, so nothing on this page is sourced from it.

You do not pick songs from a list at the start — you meet them. Story chapters funnel you into encounters: a CONNECT screen compares your five-card loadout against the opponent’s power, and PLAY starts the dive. The song plays; the story continues around it.

1. 1

   Meet songs where the story meets you

   The video opens exactly where a new player lands: a CONNECT loadout screen for a story encounter, five card slots facing a 5,000 vs 4,000 power check. This fight — not a song list — is how In Falsus hands you your first tracks.

   

SELECT DIFFICULTY on any story song and you get its ladder — the chart levels currently open on that track, running 1–11 across the four tiers. A fresh story song shows only the rungs you have earned so far, and the ladder grows as you clear.

1. 2

   Read the ladder before you pick

   Latent Duality’s panel lists chart levels 4, 7 and 11 — three rungs, one song. The highlighted rung is where your selection sits; nothing says you must take the top. Early in the story, ladders are short by design.

   

2. 3

   Confirm the chart on the song card

   Committing flashes the song card: level 7, EVOLVED, on Latent Duality by Palme. That card is the last screen before the dive starts — the level shown there is the chart you will play.

   

In Falsus grades a dive twice. The rhythm run has its own result — rank, judgements, DIVE CLEARED — while the encounter has a separate outcome decided by card damage. The footage is blunt about the difference: a rank-A clear can still lose the fight.

1. 4

   Know what a cleared dive looks like

   FO CHA0S ends at rank A: 893 EXACT, 88 shiny EXACT, 57 NEAR, 47 BREAK and DIVE CLEARED across the line. This is the rhythm half of the verdict — it is about your hands, and it is what drives chart progress forward.

   

2. 5

   Read the failure that isn’t a fail

   Later, With Truth posts 094’808’272 and DIVE CLEARED — while the encounter reads FAILED. The toast explains it: your current Card Loadout is not strong enough to defeat this Reflection Encounter; craft stronger cards. The song was cleared; the deck lost. Nothing about the song locks back up.

   

3. 6

   Replay the fight from the Dive Overview

   The Dive Overview plots your HP line against the opponent’s across the whole song, phase by phase — the video opens it straight from a FAILED result to find where the damage stalled. The graph points at which phase to strengthen, not at whether to replay the song.

   

When a wall appears, the game points at your cards, never at a song lock. Midway through the footage, crafting itself levels up: Mastery Challenges arrive, completed challenges reshape recipes, and the Iota budget behind your cards grows.

1. 7

   Catch the unlock toast in the hub

   A hub toast announces it: Mastery Challenges have been unlocked in Crafting — navigate to Crafting to try this now. It appears on its own as the story advances: another system settling into place around the songs you already have.

   

2. 8

   Turn challenges into crafting headroom

   Completing one flashes Mastery Challenge Complete over the recipe, and the reward line lands as a crafting skill that raises how much Iota Nia can use when crafting. More Iota budget means stronger cards — exactly what the FAILED encounter above was asking for.

   

Clearing a chapter does not shelve its songs. The Timeline collects every story beat as day-by-day nodes across the arcs — the community wiki names them Arc 1: The First Lie, Arc 2: A Past Best Untold and Arc 2.5: Every Moment — and any memory entry can be replayed as a song.

1. 9

   Watch the Timeline itself unlock

   After an early chapter, a dialog confirms it: Timeline Unlocked — Story’s Timeline is now available. From this point, every song the story has introduced has a fixed address you can return to.

   

2. 10

   Read a timeline like a save file

   Arc 1: The First Lie lays out as four character lanes — Nia, Mei, Ayame, Iris — with numbered day nodes sliding toward the chapter’s final days. Each node is a memory; memories hide the story’s song encounters.

   

3. 11

   Remembrance adds dives beyond the story

   Progress also drops new modes into the same flow: a Remembrance Unlocked card introduces Old Friends as a NEW dive, with its Iota drop pool and trait slots listed on the card itself. Remembrance dives are where crafting material comes from — songs again, in a different coat.

   

4. 12

   Challenge any memory you have cleared

   Arc 2: A Past Best Untold opens its own timeline, and selecting a memory entry brings up its card with a START button — the replay door. Early on, this is the closest thing In Falsus has to a free-play list: the story is the menu.

   

The hub’s MUSIC PLAY panel is where unlock progress becomes visible: a SELECT SONG shortcut with your ULTIMATE clear counters on it. And when a ladder grows, the game says so out loud.

1. 13

   Find your counters in Music Play

   The hub menu points at MUSIC PLAY — SELECT SONG — with an ULTIMATE card showing EX COUNT 1/18 and CLEAR COUNT 10/18 at this point in the run. Eighteen ULT charts existed for this player mid-story; those counters are the cleanest readout of cleared songs.

   

2. 14

   FORBIDDEN announces itself

   Right after the With Truth clear, a red banner: New Difficulty Unlocked — songs can now be challenged on FORBIDDEN LV 11. That is the FBD tier arriving: level 11 charts, the top of the 1–11 range, unlocked by playing rather than by menus.

   

3. 15

   See the ladder grow

   With Truth’s SELECT DIFFICULTY now lists 1 / 4 / 8 / 10 — four rungs where most story songs show three, with the newly opened top levels highlighted. Ladders differ per song; the level you cleared is the one that stretched it.

   

4. 16

   Take the new rung straight into a dive

   One screen later the card confirms the pick: level 8, ULTIMATE, on With Truth by ARForest feat. nayuta. New unlock, next dive, no detour — this loop of clear, banner, taller ladder, dive again is how a song collection levels up in In Falsus.
