Dirt Town terrain
Dirt Town simulates a reactive ground layer where each material class handles differently under blades, buckets, and tires. The demo highlights how loose sand contrasts with soil and how water flows across cuts, while Early Access contrasts sand with clay and introduces rainfall that forms creeks and puddles. Across both builds, ground moisture directly changes tire grip and how dirt shifts.

Sand is the primary bulk cargo in the demo—with 40 t delivery targets to the gravel pad and the bay—and appears in both editions as a loose granular material.
Hauling gravel is part of the core earthmoving loop across both builds, while crushing gravel to reinforce soft road surfaces is an Early Access side mission.
Moisture is active in both the demo and Early Access simulations, governing tire traction on grades as well as how wet earth clumps or slides.
Soil serves as the baseline earth material contrasted against loose sand in the playable demo simulation.
Clay replaces soil as the cohesive contrast material against sand in the Early Access terrain simulation.
Movable rocks and boulders appear in both editions, including the demo hill-boulder task and Early Access rock-drilling and hooking tools.
Water flows dynamically in the demo river and channels, while Early Access expands hydrology with weather rain that pools into creeks and puddles.
Early Access tools
These six field tools and terrain interactions belong to the Early Access feature set and are not included in the smaller demo simulation list.
Place survey sticks along a grade, then engage auto level (J) on the dozer blade to cut an even roadbed.
Hook heavy tow chains between vehicles for solo or four-player co-op recovery when a hauler bogged in wet dirt needs a pull.
Exit the cab on foot to walk the job site, climb steep embankments, and clamber directly onto heavy machinery.
Bore anchor holes into large rocks so chains or attachments can hook and drag boulders clear of the right-of-way.
Flatten standing trees and thick brush with heavy tracks and blades when pioneering a fresh haul road.
Swap buckets and work tools using a physical hooking coupler system controlled from the cab.

Terrain physics and site engineering
Driving a loaded hauler over loose sand requires different momentum and road prep than crossing packed soil or sticky clay. Surfacing soft sections with crushed gravel and rolling them with a compactor keeps multi-tonne loads from sinking.
Because water flows across the topography you dig, cutting a trench or breaching a bank redirects runoff. In Early Access, rainfall actively feeds creeks and surface puddles, and players can drain a flooded swamp to uncover buried resources.
Pioneering a route through raw forest or quarry benches involves knocking down trees and brush with the dozer and relocating oversized boulders. Early Access adds rock drilling so operators can set an anchor point and tow heavy stone with chains.
Several terrain sites draw on high-resolution elevation data credited to swisstopo open data and OpenStreetMap contributors under the Open Database License (ODbL), giving valleys, riverbanks, and quarry slopes authentic relief.
