NEON ABYSS
Neon Abyss Seed Machine & Replay Notebook
Veewo locates the seed machine beside character select. A seed replays a run from a fresh start; it is not a saved inventory or a promise of an overpowered route.
The official update archive names one historical code below. We have not replayed it on current PC or console builds, so it is not a current Xbox, OP or broken-seed recommendation.
Official Historical Seed
Veewo published this code under 1.3.1.30 Exp-Branch. The archive does not establish compatibility with a current release, a console port or Neon Abyss 2. No current replay test is claimed.
| Seed | Published context | Source | Current verification |
|---|---|---|---|
| 20201031 | Halloween surprise; 1.3.1.30 experimental branch | Veewo official update archive | Not replay-tested on current builds; historical example only |
Where to Enter a Seed
The official FAQ says the seed machine is near character select. Replaying always starts fresh rather than resuming the original run.
- Record the code shown by the original run and note its build and platform.
- Return to character select and use the nearby seed machine.
- Enter the recorded code exactly and begin the replay.
- Compare the opening layout and rewards with the original record. If they differ, retain the mismatch instead of calling the seed verified.
Replay Context and Achievements
Record the game, code, build, platform, character, difficulty and observed route before sharing. The notebook below does not validate the code inside the game.
The wiki Seed page is a prerelease source and warns that seeded runs disable achievements. Keep achievement attempts separate; this is not a newly tested rule for every current port.
Generation Is Done by the Game
The game supplies the run-generation code. This page records and compares codes; it does not reconstruct the dungeon algorithm, produce tested codes from random letters or predict rewards.
Records are held only in this page session. Import and export use local JSON files, with no upload or persistent browser storage.
Why This Is a Replay Worksheet
No public format, algorithm, character set or validated candidate library was found in the checked sources. This worksheet records real in-game seeds and compares replays. It does not generate seeds.
| Tool question | Verified answer |
|---|---|
| Input | A seed copied from the game or a source with its build and platform |
| Output | A replay record and comparison checklist, not a guessed seed |
| Validation | Replay in the same game/build/platform context |
| Guarantee | None; “OP”, broken or universally valid is not claimed |
