Sandustry Map guide

Unlock the Map and verify its current control

Research the Map during the early progression route, then open the current key-binding screen before leaving the factory. The Map unlock is documented, but a reliable current default key is not confirmed. Recording the binding used by your installation avoids a failed return trip after an update or custom control change.

Open the Map once at the surface factory and again at the bottom of the first main shaft. Compare the two positions to learn its scale and orientation before using it for a long expedition. The world visible in the guide is much larger than the starting work area, so the Map becomes useful well before every factory feature is unlocked.

• Research the Map.
• Check the active key binding.
• Open it at two known locations.
• Identify the surface factory and main shaft before exploring farther.

Plan relative routes in a procedural world

Treat the Map as a picture of your save, not as a coordinate chart shared by every player. Sandustry generates the world procedurally, so a cave, Artifact room, ice pocket, or objective shown to the left in a video may appear elsewhere in your world.

Plan routes from landmarks that already exist in your save: the surface factory, a vertical transport shaft, a large fluid basin, or a distinctive indestructible room boundary. When a direct tunnel meets hard terrain, return to the Map and plan a route around it instead of spending energy against material your current tool cannot remove.

Use Activity Heat to diagnose a large factory

Unlock Activity Heat when the production line has spread far enough that you cannot watch every section on one screen. The view highlights areas where factory activity is occurring. In the supplied full route, a quiet area helped direct attention to a filter that was preventing Copper from continuing through the line.

Start at the last output that is still moving, then inspect the first quiet segment immediately downstream. Check material type, filter direction, free receiving space, power, heat, and fluid supply at that boundary. Activity Heat tells you where to inspect; it does not identify the broken machine for you.

• Confirm the input lane is active.
• Find the first quiet downstream section.
• Inspect the machine or filter at that transition.
• Restart one small batch and watch the activity return.

Follow yellow arrows for active objectives

Use the yellow arrow on the Map or Minimap when the current objective points to a world event. The observed progression route uses this arrow to locate the Strataform and secure the Fluxbound Stratacore. Fixed depth or direction instructions from another save are less reliable than the objective marker generated for yours.

Reopen the Map after a major detour, especially when an indestructible wall forces you around a room. The arrow gives a direction, not a guaranteed clear tunnel. Keep enough energy to dig an approach and return, and leave the factory in a stable or safely stopped state before following a distant target.

Use the Map during Artifact and puzzle searches

Environmental arrows and unusual enclosed spaces can reveal puzzle areas while you explore. Use the Map to understand the unexplored space around a room and to find an accessible side, but solve the room from its local tool, material, button, and Foundation hints.

The basic Artifact Locator later provides a general direction when filled with Void Juice, while the Triangulation Lens upgrade enables exact guidance. Compare the indication with accessible space on your Map and approach indestructible terrain from another side.

Know what the current evidence does not confirm

Do not rely on universal Artifact coordinates, puzzle numbers, or an unconfirmed default Map key. Current references also do not verify a complete marker creation and deletion workflow, so this guide does not promise custom pins.

A useful Map check ends with a concrete decision: the next shaft to dig, the first quiet machine to inspect, or the direction of an active objective. If the view does not change that decision, return to the local factory or room and read its visible signals.

• Use save-specific landmarks instead of global coordinates.
• Use Activity Heat as a diagnostic clue, not an error report.
• Use objective arrows for events and local hints for puzzle mechanisms.
