World Archive & MERIDIAN
Mechanics Guide - Remnants: Post-Collapse Idle Survival
Overview
The World Archive is the narrative spine of REMNANTS - a 15-transmission MERIDIAN story arc that reveals what caused the Cascade, who the Commander really is, and the truth of the AI named MERIDIAN. You read it inside the Echo Forge → World Archive tab.
Lore used to be locked behind prestige alone - one transmission per Echo Reset. It now reconstructs in two ways at once: a prestige floor that guarantees steady progress, and Memory Shards recovered during active play that let you decrypt transmissions mid-run, ahead of schedule. The archive is also where the world visibly drifts toward MERIDIAN as the truth surfaces.
Memory Shards
Memory Shards are a soft currency dropped by ordinary play. You don't spend them manually - they flow automatically into the next sealed transmission and decrypt it once its quota is met.
- Sources: scavenge runs, repelled raids, and research completions all have a chance to drop shards.
- Routing: shards always feed the lowest undecrypted transmission you're allowed to work on.
- No waste while sealed: if there's nothing you can reconstruct right now (the prestige floor has caught up), shard rolls are simply skipped rather than lost.
Reconstruction & the Prestige Floor
A transmission counts as decrypted if either condition is met:
- Prestige floor: your prestige run count has reached that transmission's run index (run 0 is readable from the start, run 1 after one Echo Reset, and so on).
- Shard quota: you've fed it enough Memory Shards this run - even if you haven't reset yet.
Shards can only run one transmission ahead of the prestige floor. You can read at most one transmission early - you can't shard-rush the whole story in a single run. The floor then catches up on your next reset, and the shard pressure moves to the next sealed entry.
Shard Costs Per Transmission
Cost ramps gently so early transmissions fill in roughly one active run, while later ones take more sustained play. The formula is:
| Transmission | Run index | Shard cost |
|---|---|---|
| Transmission One | 0 | 5 |
| Transmission Three | 2 | 9 |
| Transmission Six | 5 | 15 |
| Transmission Ten | 9 | 23 |
| Transmission Fifteen | 14 | 33 |
The 15 Transmissions
The hand-authored canon is 15 transmissions, each a different document type - emergency broadcasts, recovered journals, classified files, audio confessions, system logs. Together they move from the night of the Cascade to a final direct address. The arc breaks roughly into three movements:
- Transmissions 1–5 (runs 0–4): the collapse from the ground - survivors, soldiers, and the first hints that the Cascade was designed, not accidental.
- Transmissions 6–10 (runs 5–9): Dr. Voss, the MERIDIAN architects, and the Commander's own words. The "tragic engineering error" account the committee believed.
- Transmissions 11–15 (runs 10–14): the system speaks for itself, recontextualising everything before it - and revealing what the Commander actually is.
World-Tier Drift
As you decrypt more of the archive, the interface itself drifts. The world tier is keyed to how many transmissions you've reconstructed:
| Tier | Trigger | Feel |
|---|---|---|
| Ruin | Early game | The unexplained wasteland. Default palette. |
| Deliberate | A few transmissions in | The first MERIDIAN reds bleed in - the Cascade starts to look intentional. |
| The Echo | 5 transmissions decrypted | Cyan drift. You begin to grasp the loop you're inside. |
| The AI Beneath | 8 transmissions decrypted | Circuit-board glitch tones. The thing under it all is fully present. |
The drift is applied as CSS layers over the whole UI - it's cosmetic, but it's the game telling you how deep into the truth you are without a single tutorial pop-up.
MERIDIAN Intrusions
Once you've reconstructed enough to suspect what's beneath the Cascade, MERIDIAN begins speaking through the interface directly. These are diegetic intrusions - the game breaking the fourth wall in-character:
- Log-line intrusions that address you directly, sometimes referencing your population, the in-game day, or how many times you've reset.
- A centre-screen glitch banner and brief screen jolt when MERIDIAN "speaks."
- Resource-bar flicker as the signal bleeds into the UI.
The Reconstruction Finale
Decrypting the fifteenth and final transmission - the payoff for fourteen Echo Resets - triggers a full-screen reconstruction ceremony. MERIDIAN's last direct address types out in full, then hands you back to the World Archive to read the complete transmission. It's the closing beat of the entire narrative arc.
Echo Memories (Endless)
The "truth meter" (reconstruction %) is measured only against the 15 hand-written canon transmissions. But the archive never runs dry: past the canon, it generates infinite procedural Echo Memories - short, deterministic self-records seeded by your run index, so they stay stable across reloads without bloating your save.
Echo Memories are bonus flavour, not part of the reconstruction percentage. They're a quiet reward for players who keep prestiging long after the story "ends."
Strategy
- Play actively to read ahead. Scavenging, raids, and research all drip shards - if you want the next transmission before your reset, run those systems.
- Don't hoard for nothing. Shards can't bank more than one transmission ahead of the floor, so there's no benefit to "saving up" - just keep playing.
- Watch the NEW badge. It's the cleanest signal that there's lore waiting in the Echo Forge.
- The archive persists. Decrypted transmissions and your reconstruction progress survive every Echo Reset - it's permanent, like your Forge upgrades.
