// Box Index
This page focuses on the highest-confidence Safe Box information in Pragmata: how many boxes exist across the full game, which sectors are densest, which boxes are ability-locked, and when it is smarter to clean them up later instead of forcing a bad route. Where location-level details vary between outlets, this page stays with the broad route-safe version.
Total Boxes
70
Cross-sector counts add up to 70 Safe Boxes in the full campaign.
Most Boxes

// Sector Totals
| Sector | Safe Boxes | What To Expect |
|---|---|---|
| Solar Power Plant | 3 | Short opener, but one box route is cleaner after `Lim Eraser` backtracking. |
| Mass Production Array | 17 | Large sector with multiple neighborhoods and several late-sweep-friendly paths. |
| Terra Dome | 20 | Biggest Safe Box sector, with multiple branches and a few `Cleansing` holdouts. |
| Lunum Mines | 17 | Vertical routes, `Holo-Walls`, and several late cleanup boxes tied to `Cleansing`. |
| Central Port | 13 | Less total than midgame sectors, but denser in final-lab style rooms and cleanup routes. |
// What They Do
Broad guide coverage treats Safe Boxes as one of the most reliable ways to collect upgrade-driving loot, especially Lunafilament and other high-value optional rewards.
Some boxes are trivial; others are effectively route puzzles hidden behind `Holo-Walls`, branch choices, or story-locked crystals. That is why Safe Boxes are often the collectible type most likely to create return trips.
If you care about clean sector completion, Safe Boxes are too numerous to ignore. They are one of the main reasons players miss full completion on a first sweep.
// Backtracking
The first major Safe Box backtracking wave happens after you learn how to break blue crystal barriers with Lim Eraser. Reliable sector coverage and blue-crystal guides point back to missed paths in Solar Power Plant and Mass Production Array.
The later cleanup wave centers on Cleansing. High-confidence coverage specifically calls out late-access Safe Boxes in Terra Dome and Lunum Mines, with Central Port progression acting as the trigger point for that return route.
The safest final pass is still Unknown Signal Mode. Multiple collectible guides agree that nothing is permanently missable, and that post-story cleanup keeps your collected items while exposing the remaining gaps sector by sector.
// Best Route
If your goal is zero wasted movement, the cleaner route is often: main story first, then `Unknown Signal Mode`, then a sector-by-sector Safe Box pass starting from the earliest backtrack-heavy areas and ending in Central Port.

Pure Lunum
Safe Box routing overlaps heavily with Pure Lunum cleanup and spend planning.
Red Zones
Red Zone rewards often explain why some Safe Box cleanup passes feel more valuable than others.
Mass Production Array
Sector 2 is where blue-filament backtracking starts becoming part of the route.
Terra Dome
The single biggest Safe Box sector, and one of the easiest places to desync your route.
