Sandustry Map Guide: Every Biome, Resource, and Secret Location

Why Understanding the Sandustry Map Matters

The Sandustry map is far more than a simple sandbox — it is a layered, procedurally-influenced world packed with biomes, hidden caverns, finite water pools, and rare resources that gate your progression. Whether you are setting up your first shaker line or hunting for artifacts in deep underground chambers, knowing the Sandustry map layout determines whether your factory thrives or collapses under its own slag pile. Every layer presents unique challenges, from water scarcity on the surface to bedrock walls and crack stone barriers below.

Player experience and community reports consistently highlight that map awareness is the single biggest factor in early-game success. The terrain dictates where you can build conveyors, how you route wet sand, and when you unlock critical tools like the flamethrower and rocket launcher. This guide breaks down every zone, resource node, and navigational tip you need.

Surface Layer: Your Starting Foundation

The surface is where every Sandustry playthrough begins. You spawn as a small green character with a shovel, a grabber, and zero cash. The starting area typically features a modest water pool, a patch of mineable soil, and rock formations that cannot be destroyed in the early game.

Key Surface Features

The most important strategic decision on the surface is water conservation. Sand consumes water to become wet sand, and the starting pool is finite. Community reports indicate that players frequently exhaust their initial water supply before discovering underground pools, which can stall production entirely.

Surface Automation Tips

• Build shakers close to the water pool to minimize transport distance
• Use launchers for vertical transport — they function as diagonal or vertical conveyor belts
• Create a dedicated slag containment pen early; slag accumulates rapidly
• Leave space between your gold collectors and shaker lines for future filter integration
• Queue conveyor blueprints even when terrain is blocked — they auto-build once the path clears

Underground Caverns: The Resource Highway

Beneath the surface lies an interconnected network of caverns that form the backbone of mid-game expansion. The Sandustry map features multiple underground layers, each containing distinct resources, hazards, and secrets. The game provides subtle visual indicators — such as directional arrows on cave walls — to guide players toward points of interest.

Underground Resource Breakdown

Navigating the Cavern System

The underground layout is roughly diagonal, which works to your advantage. Launchers excel at moving resources diagonally, making them ideal for transporting wet sand from deep mining operations back to surface-level shakers.

Key navigation notes from player experience:

• Caverns connect laterally — what appears to be a dead end often loops back into a larger chamber
• Arrows on walls indicate nearby points of interest, including artifacts and resource motherlodes
• Light is a major issue underground — research wall-mounted lights early to illuminate dark passages
• Water pools exist underground but cannot have conveyors or blocks built underneath them
• Steam rises and converts to rain when it reaches the ceiling, creating a renewable water source

Water Management: The Map's Most Critical Resource

Water is the lifeblood of every Sandustry factory, and the map's water distribution is intentionally scarce. The starting surface pool depletes as you convert sand to wet sand, forcing players to explore deeper for additional sources.

Water Sources by Map Layer

The steam-to-rain cycle is a game-changing discovery. By heating water with the flamethrower, steam rises to the ceiling and converts into rain, which can be collected in basins. This creates a renewable water loop that sustains production indefinitely. Players can even direct steam horizontally by controlling where heat is applied, channeling rain to specific collection points.

Setting Up a Renewable Water System

1. Locate a cavern with a ceiling above your factory basin
2. Research and unlock pipes, pumps, and liquid vents
3. Place a pump in an underground water source
4. Connect pipes from the pump to a liquid vent near your surface basin
5. Use the flamethrower to heat excess water — steam rises and returns as rain
6. Collect rain in your processing basin for continuous wet sand production

Tools and Map Progression Gates

The Sandustry map is designed with progressive gating — certain areas and resources remain inaccessible until you unlock specific tools. Understanding this progression helps you plan your research tree efficiently.

Tool-to-Terrain Unlock Matrix

Flux Site: The Upgrade Currency

Flux sites are scattered throughout the map, embedded in stone walls and cavern floors. Unlike sand and slag, flux sites are destroyed in place and instantly added to your inventory — no transport required. They fund critical upgrades:

• Material Scanner: Reveals terrain composition when hovering
• Thrust Amplifier: Increases flight and movement speed
• Rapid Fire: Boosts gun firing rate for faster mining
• Quick Dig: Reduces shovel cooldown
• Bullet Count: Increases bullets per shot by three

Player experience suggests that the largest flux site deposits are found in deep caverns surrounded by bedrock, accessible only through narrow shooting positions. One community-reported motherlode yielded over 1,000 flux in a single deposit.

Artifacts and Secret Locations

The Sandustry map contains at least two artifacts hidden behind crack stone barriers. These artifacts appear to be tied to the main mission objective and are not usable as functional items — they serve as progression milestones.

Known Artifact Locations

Reaching the second artifact requires the rocket launcher, which costs over 1,000 gold to unlock through the Guns 2 research node. The path involves extensive exploration through connected cavern systems, past lava formations, red soil deposits, and amethyst-like formations.

Factory Layout Strategies by Map Zone

Surface Processing Hub

Your surface should serve as the primary processing center. Dedicate zones for:

• Shaker array: Multiple shakers in a row for parallel wet sand processing
• Gold collection: Expandable storage area — gold fills quickly at scale
• Slag management: Multi-tier slag piles with launcher-based redistribution
• Filter integration: Conveyor filters separating slag, wet sand, and regular sand

Underground Mining Network

• Use launchers for diagonal resource transport from deep caverns
• Build conveyor lines along cavern floors for steady sand extraction
• Install lights at regular intervals to maintain visibility
• Position flux site mining operations near upgrade-relevant tools

Kinetic Slag Press Setup

The kinetic slag press requires burnt slag as input. The processing chain is:

1. Collect raw slag from shaker output
2. Burn slag with flamethrower (drastically reduces volume)
3. Transport burnt slag via filtered conveyor to the kinetic press
4. Press outputs gold and spores — filter gold to collectors, spores to storage
5. Drop burnt slag from height — the press requires a vertical drop distance

Research Priority Roadmap

FAQ

What is the most important resource on the Sandustry map?

Water is the most critical resource. The Sandustry map features finite water pools that deplete as you process wet sand. Without water, production stops entirely. Players should prioritize finding underground pools and setting up a steam-to-rain renewable cycle using the flamethrower and pipes system.

How do I access secret areas blocked by crack stone on the Sandustry map?

Crack stone barriers require the rocket launcher, unlocked through the Guns 2 research node for over 1,000 gold. The gun and shovel cannot damage crack stone. Behind these barriers, players have found artifacts and additional resource deposits, making the rocket launcher a key exploration tool.

Can I build structures underwater on the Sandustry map?

No. Player experience confirms that conveyors, blocks, and other structures cannot be built underwater or beneath water tiles. This limitation makes launchers essential for moving resources across water-filled caverns, as they can be placed on adjacent terrain and launch materials diagonally over water obstacles.

Where are the best flux site deposits located?

Community reports indicate that the largest flux site deposits are found in deep underground caverns, often surrounded by bedrock. These deposits can yield over 1,000 flux in a single location. Players should upgrade their gun's firing rate and bullet count before mining these deposits for maximum efficiency, and use the material scanner upgrade to locate them more easily.
