Sandustry Research Tree

Shaker — separates Wet Sand into Gold + Residue.

First unlock, always. This is the engine of your economy.

Conveyor Belt + Launcher.

Without logistics you move everything by hand. Unlock right after Shaker.

Hover mode (Space bar) — fly over buildings.

Quality of life; grab it after your first conveyor.

Map + Minimap.

Helps planning but not urgent early.

Flare Gun — temporary illumination underground.

Skip until you actually need to go underground regularly.

Filter — conveyor that only passes specific elements.

Critical for separating mixed streams (e.g. Copper Ore from Sand).

Sprint Boost (Shift) — temporary speed.

Wall Light — permanent mounted light.

Cost not yet published on wiki.

Flamethrower — burn Residue, melt Ice, boil Water to Steam.

Unlocks the burn-Residue-for-bonus-Gold loop and the renewable Water cycle.

Kinetic Press — processes Burnt Residue into more Gold + Seed.

Closes the Residue → Gold loop. Pair with Flamethrower.

Flashlight — illuminates where you aim.

Sweeper Drones — auto-collect loose materials.

Big labor saver once your factory is producing.

Conveyor Portal — cross streams without mixing.

Burner Belt — ignites flammables in transit.

Requires Thermal Buffer for heat.

Thermal Buffer — stores and distributes heat.

Backbone for Pyro Dispenser, Burner Belt, Smelter.

CryoBlaster — infinite Snow for renewable Water.

Unlock once you start running low on natural Water.

Pipe + Pump + Liquid Vent.

Essential for moving Water, Lava, Liquid Copper/Gold.

Planter Box — Wet Seed → Flower (Gold + Amethelis).

Gun — ranged mining.

Pyro Dispenser — automated fire puff every 3s.

Clearing Frame — slow belt for pushing floating items.

Vacuum — suck materials into a tank.

Activity Heatmap overlay on map.

Aerokinetic Fan — blows powders (great for Amethelis).

Digger Drone — autonomous mining.

Advanced Filter — filters multiple elements incl. liquids & gases.

Steam Dryer + Condenser.

Rocket Launcher — explosive mining.

Prereq for Drill. Get this before late Tier 4.

Conveyor Belt Mk.2 + Launcher Mk.2.

Corraller — captures Critters.

Hauler Drone — autonomous material transport.

Recon Drone — scouting.

Snowmaker — Water → Snow using Energy.

Florinol Battery — stores Florinol as Energy.

Prereq for Drill and Copper Mold. Foundation of the Energy economy.

Drill — powered mining through hard materials (uses Energy).

Required to mine Stone, Copper Ore, Solidite and beyond.

Smelter — Gold → Liquid Gold, Copper → Liquid Copper.

Major storage-density upgrade for your Gold bank.

Energy Siphon — moves Energy between storages.

Flux Emanator — Voidbloom → Fluxite (renewable upgrades).

Late-game Fluxite source. Essential once natural deposits run out.

Copper Mold — Liquid Copper → Power Brick (Energy storage).

Void Rift — produces Void Seeds for the Void chain.

Energy Connector — pipes Energy between structures.

Steam Turbine — automated power generation.

Laser — continuous mining of hard materials.

Best mining tool in the game. Save up.

Recall Shard — teleport back to a Voidbloom portal.

Locator — scans for hidden artifacts (uses Void Juice).

Synthesizer — transmutes materials using Energy.

Late-game material generation. Tier 6 capstone.
