Sandustry Map, Underground Biomes & Resource Geography

1. World Generation & Scale

Early Access Map vs Demo: The full Early Access map of Sandustry is roughly 15 times larger than the introductory demo terrain. It features seamless vertical progression stretching from sunbaked desert peaks down to primordial subterranean lava mantles.

Procedural Seed Variation: While core ancient temples, key puzzle chambers, and primary biome layers appear on all seeds, specific ore vein clusters (Copper, Fluxite, Coal) and underground aquifer chambers generate with seed-dependent offsets.

2. Major Biome Layers & Depth Distribution

Layer 1: The Great Dune Surface (Depth: 0m to -50m):

Dominant Materials: Dry Sand, Fine Silt, Loose Sandstone, Sparse Cacti.

Hazards: Shifting dunes, surface windstorms, low ambient water density.

Strategic Value: Primary starting zone; ideal for expansive solar collection arrays and high-capacity staging basins.

Layer 2: The Subterranean Aquifers & Caverns (Depth: -50m to -250m):

Dominant Materials: Wet Sand, Clay, Underground Springs, Blue Fluxite Pockets.

Key Features: Natural water reservoirs critical for early-game Shaker setups and steam power networks.

Layer 3: The Copper Crags & Crystal Veins (Depth: -250m to -600m):

Dominant Materials: Brownish Copper Ore, Dense Granitic Rock, Amethelis Geodes.

Key Features: Rich industrial ore beds. The first zone where heavy mechanical drilling and automated smelting complexes must be constructed.

Layer 4: The Magma Chambers & Geothermal Trenches (Depth: -600m to -1200m):

Dominant Materials: Molten Lava, Obsidian, Basalt Columns, Volcanic Sulfur.

Hazards: Extreme ambient temperature, structural melting, pressurized magma eruptions.

Strategic Value: Infinite thermal energy for advanced smelting, high-pressure steam boilers, and Scoria stone farming.

Layer 5: The Void Abyss & Ancient Ruins (Depth: -1200m+):

Dominant Materials: Voidbloom Flora, Voidjuice Pools, Singularity Dust, Ancient Alien Architecture.

Key Features: Houses Tier 5 Ancient Artifact chambers, cosmic Swarm Consoles, and world-shaping puzzle temples.

Using Waypoint Beacons: Because the map has massive vertical depth, digging winding shafts can disorient players. Place illuminated Waypoint Beacons at major vertical shaft intersections to mark safe extraction routes.

Mapping Ancient Artifact Temples: Ancient temples emit distinct low-frequency acoustic hums. Players equipped with the Material Scanner (Tier 2 upgrade) can detect temple geometry through up to 80 blocks of solid rock.
