Quick Answer
Unlock the sandustry map and minimap through Research, then use the minimap’s objective direction marker to stay oriented while digging and expanding. Reserve visible space around Water, factory modules, and future transport corridors before excavation makes those routes awkward. Mark or remember blocked locations and return with the right tool instead of forcing every obstacle immediately. This article covers the official vanilla Map and Minimap only; custom map loaders, downloadable maps, seed behavior, and exact reveal rules are Pending confirmation and are not linked here.
Distinguish Map and Minimap Jobs
The official beginner guide says the minimap shows the world around the player beyond the main screen. It also says current objectives receive a yellow arrow on the minimap pointing toward their direction. The Research page lists a single unlock for Map and Minimap, with an Activity Heatmap as a later separate feature. Exact zoom, marker, and reveal controls are not described in those pages, so use the current control screen for bindings.
| View | Confirmed use | Practical planning job |
|---|---|---|
| Minimap | Nearby awareness and objective direction | Prevent short-range navigation mistakes |
| Map | Broader unlocked view | Compare exploration routes and factory footprint |
| Activity Heatmap | Later map upgrade | Inspect activity after verifying its live legend |
| Custom maps | Not covered by these official sources | Pending confirmation; no downloads are provided |
Open the larger view before committing to a long tunnel or new processing wing. A path that appears convenient on the play screen may intersect a reservoir, cave, or existing route when viewed in context. The map is a planning layer, not just a completion checklist. Revisit it after major terrain changes because Sandustry’s world is fully destructible.
Plan Exploration Around Objectives
Use the yellow objective direction as a heading, not proof that a straight line is safe or possible. The terrain between you and the target may include Crackstone, liquids, or puzzle geometry that requires later tools. Survey nearby open spaces and approach from a direction that does not drain Water into the factory. The official beginner guide advises returning to ancient puzzles later when the necessary tool or resource is missing.
- Check the current objective text and minimap arrow.
- Open the Map to compare direct and indirect routes.
- Protect reservoirs and factory foundations before digging.
- Stop at a barrier that starter tools cannot affect.
- Preserve a route back and record the location for later research.
- Recheck the Map after opening a new cavern or vertical shaft.
Avoid treating a map edge or dark region as a promise of a particular reward. Official sources describe diverse biomes, exploration, and ancient secrets but do not publish a fixed reward at every coordinate. Procedural generation is also expected to evolve during Early Access. Plan for access and recovery rather than a spoiler-specific route.
Reserve Space for the Factory
The map can prevent the factory from expanding into its own transport corridors. Separate the wet-sand front end, dry logistics, thermal processing, and exploration access so one change does not cut off another. Leave vertical space for Launchers and horizontal space for conveyors. Keep Water paths distinct from areas where Sand or Seeds must remain dry.
Use landmarks that remain readable after excavation, such as deliberate block outlines or consistent module spacing. Exact in-game marker features are Pending confirmation, so do not depend on a pin system not described by official sources. A simple spatial convention can work even when the map interface changes. The goal is to recognize where materials enter, transform, and leave at the larger scale.
Use the Activity Heatmap Carefully
The Research page says an Activity Heatmap can be unlocked on the map, but it does not explain the legend or calculation. Treat it as a diagnostic overlay whose current in-game labels define what each color means. Do not claim it measures throughput, danger, power, or drone traffic unless the live tooltip says so. Its exact data and refresh behavior remain Pending confirmation.
When available, compare the overlay with visible factory behavior. A busy area may deserve an inspection route, but activity alone does not prove efficiency. Check the physical buffers and outputs before redesigning a module. Record any map insight as a hypothesis, then validate it at the machines.
Safe Boundaries for Community Maps
Steam currently lists Workshop support and says Sandustry was built with modding and hand-crafted maps in mind. That confirms a supported direction, but it does not make every external file safe or compatible. This page provides no third-party loader, executable, archive, or direct custom-map download. Use official Steam Workshop surfaces and current developer instructions if you choose to explore community content.
Keep vanilla and modified saves separate when the current game interface permits it, and read the Workshop item’s version and dependency information. Compatibility, save migration, achievement behavior, and map file locations are Pending confirmation here. Do not follow old demo-era folder paths merely because they appear in an archived guide. The vanilla Map and Minimap guidance above remains independent of any mod.
Maintain Return Routes as the World Changes
The Steam description emphasizes a fully destructible world, so the route visible on the Map is not a permanent corridor unless you preserve it. Excavation can open a shortcut, release a material, or remove a landmark that previously made the path readable. Recheck the larger view after digging through a major boundary and confirm that the player can still return to the factory without crossing an active material stream. Exact map-update timing is Pending confirmation, so verify the displayed terrain rather than assuming an instant refresh.
Keep one main exploration route wider and clearer than temporary resource cuts. Branches can lead toward objectives, Crackstone walls, or ancient puzzle spaces, while the main route continues to provide a stable reference back to production. The official beginner guide supports returning to puzzles later and using the minimap for orientation, but it does not specify a built-in breadcrumb system. Consistent block shapes, lighting, or module boundaries are therefore planning conventions, not claimed map features.
When a new cavern exposes Water, Ice, Lava, or loose material, stop before connecting it to an established shaft. Compare its position with the wetting area, thermal wing, and player route on the Map, then create containment before the final opening. This caution follows the game’s documented material reactions and destructible terrain without predicting what a particular seed contains. The location, volume, and reward behind any unexplored boundary remain Pending confirmation.
