Quick Guide
  • Plan B: Terraform demo introduces resource extraction, factories, cities, trucks, and terraforming.
  • Start with iron and steel before expanding into mechanical parts, factories, and transport vehicles.
  • Use depots carefully because each depot must handle the correct item type and production connection.
  • Grow cities gradually by supplying concrete, oxygen, and other resources through road networks.
  • Plan for distance because truck routes can take months of in-game time across the planetary map.

Plan B: Terraform demo Overview

Plan B: Terraform is a resource-management, transportation, automation, colony-simulation, and sandbox game set on a large hexagonal planet. The demo centers on transforming a barren world into a habitable one by extracting minerals, manufacturing industrial goods, supplying cities, and expanding infrastructure.

The early game is less about rapid population growth and more about building a dependable production chain. Iron supports steel, steel supports mechanical parts, and mechanical parts unlock additional factories, trucks, and terraforming equipment. Once the basic industrial network works, concrete and oxygen become essential for city development.

Video Highlights:

  • Establishes an early iron, steel, and mechanical-parts production chain.
  • Demonstrates how factories, assembly plants, depots, and trucks interact.
  • Shows city growth through concrete and oxygen deliveries.
  • Highlights the importance of route length and transport capacity.

The demo combines factory automation with a transportation network. Instead of relying primarily on conveyor belts, you create production lines with depots and move materials between locations using trucks. This makes layout planning and route distance important from the beginning.

Extraction

Place extractors over mineral deposits and connect their output to the correct depot.

Production

Convert iron, sulfur, aluminum, and other resources into construction materials.

Transport

Use trucks, roads, depots, and road stops to move goods between industrial zones and cities.

Terraforming

Supply growing settlements with oxygen and infrastructure while expanding the habitable planet.

Layout Tip

Keep early production chains compact. Short routes make it easier to identify missing materials, incorrect depot settings, and factory bottlenecks.

Early Production Chain Setup

The strongest opening for the Plan B: Terraform demo is a compact industrial chain built around iron. Start by locating an iron deposit, placing an extractor, and adding a depot nearby. Set the depot to accept iron before adding downstream buildings.

Factories and assembly plants do not automatically understand every intended material. Each building must be configured for its recipe, while depots must be assigned the item they store or distribute. A wrong setting can make a production line appear inactive even when the resource supply is available.

Recommended Opening Order

1

Find Iron and Place an Extractor

Zoom out across the hexagonal planet and identify an iron deposit. Place the extractor directly over the resource area, leaving nearby space for a depot and factory.

2

Add an Iron Depot

Build a depot beside the extractor and assign it to iron. This gives the production chain a clear storage point and allows the next building to receive the intended material.

3

Produce Steel Bars

Place a factory next to the iron logistics area and configure it to make steel bars. Keep the first chain short so the initial supply remains easy to monitor.

4

Create Mechanical Parts

Use an assembly plant to convert steel bars into mechanical parts. This resource is important for producing trucks, factories, and later infrastructure.

5

Expand Industrial Capacity

Build additional factories or assembly plants only after confirming that the previous stage has enough input. Expanding too quickly can create empty buildings and confusing bottlenecks.

A useful rule is to separate raw-resource extraction, basic manufacturing, and advanced assembly into visible groups. This makes it easier to change a recipe without accidentally removing an important production step.

Avoid Recipe Conflicts

Changing a factory or assembly plant to a different recipe can interrupt the materials already assigned to that chain. Check the output depot and remaining stock before switching production.

Truck Routes and City Supply

Transportation becomes the main challenge once cities are located away from the industrial zone. Roads connect production regions with settlements, while road stops allow trucks to load and unload containers. A route may function correctly but still feel slow because vehicles travel across large distances on the planetary map.

Before assigning trucks, verify three things:

  1. The origin depot contains the correct item.
  2. The destination road stop is connected to a receiving depot.
  3. The truck is assigned to the intended origin, destination, and resource.
Transport ElementRoleCommon Error
Origin depotHolds goods for shipmentWrong item type selected
Road stopLoads or unloads containersNot connected to the intended depot
TruckMoves goods between locationsDestination or resource misassigned
Destination depotReceives city suppliesPlaced outside the useful supply area
Supply centerExtends support for city growthBuilt before enough materials are available

Concrete is one of the first important city supplies. It is produced from sulfur and can be used for roads and settlement infrastructure. Once a city needs oxygen, atmospheric extractors become part of the supply chain. These require additional industrial preparation, including aluminum bars and mechanical parts.

Route Planning Priorities

PriorityPlanning QuestionRecommended Action
1Is the source producing enough goods?Add production only after checking current output
2Is the route too long?Build a closer production or transfer area
3Is the depot accepting the correct item?Reopen the item assignment and verify it
4Are trucks waiting or overlapping?Adjust truck numbers and inspect both endpoints
5Is the city still stable?Check its supply demand and required resources

The demo’s truck logistics reward patience and organization. A large fleet does not always solve a shortage if the source factory is idle or the destination depot is configured incorrectly. Add vehicles gradually, then increase capacity when the city’s annual demand clearly exceeds current deliveries.

Reliable Supply Method

Use one clearly labeled route for each major city resource during the early game. Separate concrete and oxygen deliveries until you understand how each settlement’s demand is calculated.

Oxygen, Population, and Terraforming Progress

City growth depends on more than placing buildings. Settlements require regular supplies, and their status can change between stable and growing as demand increases. Concrete supports infrastructure, while oxygen becomes important as population rises and the settlement develops.

Atmospheric extractors are a key step toward habitability. They generate oxygen and may also produce carbon as part of the atmospheric process. The important early objective is to create enough extractor capacity and deliver oxygen to the city through a functioning logistics route.

Efficient Expansion Pattern

Begin with one main city and establish a dependable supply route before supporting several settlements. Multiple cities can share production, but long-distance transport can make shortages difficult to diagnose. A second industrial cluster near another resource deposit may be more efficient than sending every truck across the planet.

Use supply centers to support city expansion, but avoid placing them before the required construction materials are ready. The best time to expand is when the existing industrial network has spare output and your transport fleet is not already struggling with demand.

Early Progress Checklist:

  • Place an extractor over an iron deposit
  • Configure an iron depot and steel-bar factory
  • Produce mechanical parts for advanced buildings
  • Create concrete and connect it to a city route
  • Deliver oxygen with atmospheric extractors
  • Check city supply and population status before expanding

A growing city can expose weaknesses in a supply chain that appeared sufficient at a smaller population. Recheck demand after every major expansion, especially when several settlements begin requesting the same material.

Terraforming Focus

Treat population growth as a logistics milestone, not the only objective. A smaller stable city with reliable oxygen and construction supplies is a stronger base for future planetary expansion.

Advanced Demo Strategy and FAQ

After the first city becomes stable, shift from emergency construction to deliberate network design. The demo supports a relaxed sandbox approach, so there is value in improving layouts even when the immediate objective is already complete.

Higher-tier development introduces materials such as reinforced concrete, polymer bars, and high-tech parts. These resources require additional production planning and make it worthwhile to create dedicated industrial districts instead of repeatedly reconfiguring the same buildings.

Recommended District Structure

DistrictMain BuildingsPurpose
Mining districtExtractors, raw-material depotsGather iron, sulfur, aluminum, and other deposits
Steel districtFactories, steel depotsProduce steel bars consistently
Assembly districtAssembly plants, mechanical-parts depotsManufacture advanced components
Construction districtConcrete factories, road-stop depotSupply roads and city infrastructure
Atmospheric districtAluminum chain, atmospheric extractorsProduce oxygen for settlement growth

Follow these principles as the network expands:

  • Keep each material’s depot visually distinct.
  • Reserve space around factories for future production buildings.
  • Build roads in clean lines rather than wrapping them around every structure.
  • Check the destination before adding more trucks.
  • Move production closer to a city when route time becomes the primary bottleneck.
  • Preserve spare capacity for population growth and new construction requirements.

Q: What should I build first in the Plan B: Terraform demo?

Start with an iron extractor, an iron depot, a steel-bar factory, and an assembly plant for mechanical parts. This chain supports early factories, trucks, and further expansion.

Q: Why is my factory not producing anything?

Check whether the factory has the correct recipe, whether its input depot stores the right item, and whether the production buildings are connected through the intended logistics setup.

Q: How do I grow a city?

Supply the settlement with required infrastructure and resources, including concrete and oxygen as development advances. Use supply centers and reliable truck routes to maintain demand.

Q: Should I build more trucks when a city lacks supplies?

Not immediately. First inspect the source factory, depot item type, road-stop connection, and destination assignment. Add trucks after confirming that the production chain is actually supplying goods.

Final Strategy

Build for clarity before scale. A compact, correctly configured production chain is easier to expand than a large network filled with mixed recipes and unclear truck destinations.
