tips

Tips for Captain of Industry are mostly about keeping your production balanced, avoiding bottlenecks, and using the map efficiently. Good planning saves fuel, maintenance, water, and a lot of rebuilding later.

Layout and terrain

Flattening, ramps, and access

Use [Terrain Leveling](/en/captain-of-industry/research/terrain-leveling) to combine mining and dumping into one designation. It is useful for flattening ground or setting up ramps: material below the designation is dumped, and material above it is mined. For mining to work, the designation must be inside a mine tower area.

When you plan transport routes, remember vehicle clearance. Trucks, excavators, and logging machines need a width of 3 tiles to pass. Mega Excavator is much taller and cannot pass under conveyors or pipes, so it often needs vehicle ramp solutions instead of ordinary crossings.

Vehicle Ramp Small lets vehicles cross obstacles such as transport lines. Level Crossing allows small and medium vehicles to safely cross railway tracks, while Level Crossing Large allows all vehicles to cross safely.

Retaining terrain

Retaining Wall Short prevents terrain from collapsing. It can be placed below the surface to support mining and above ground to support dumping. Walls collapse if they hold more than their height limit or if they are overfilled, so they are a support tool, not a permanent dump.

Shoreline placement

Cargo docks are easier to place if you first straighten an uneven shoreline by dumping excess material. This is especially useful when planning large port layouts. Cargo Depot (2) reserves space so it can later be upgraded to Cargo Depot (4) without demolition.

Water and desalination

Water sources and rainfall

Groundwater is finite, but it regenerates slowly through rainfall. The amount recovered depends on reservoir capacity and rain intensity. Larger reservoirs regenerate more water per day. Rainwater Harvester and farms also collect water from rain, but their output is much smaller than wells.

In dry climates, groundwater depletion is a real risk. Keep an eye on reserves and use Thermal Desalinator if rain is unreliable.

Desalination choice

When using steam from power production or industrial exhaust, there are two broad approaches:

Run depleted steam into cooling towers and use a separate desalination setup to replace the lost water.
Use vacuum desalination to turn depleted steam into water instead of spending extra fuel on high steam.

Vacuum desalination can save fuel, but it needs far more desalinators to match the same output. The practical lesson is to plan your water system around the steam you already have, not just around the theoretical recipe.

Farming and food

Fertility and fertilizer

Fertility can be raised above 100% only with [Fertilizer I](/en/captain-of-industry/product/fertilizer-i) or [Fertilizer II](/en/captain-of-industry/product/fertilizer-ii). [Fertilizer (organic)](/en/captain-of-industry/product/fertilizer-organic) caps at 100%, while Fertilizer I reaches 120% and Fertilizer II reaches 140%. The farm’s green slider must be set to the desired fertility level.

Higher fertility costs more fertilizer because it must also cover the farm’s natural fertility consumption. If you push for high fertility, make sure your fertilizer production keeps up.

Crop rotation

Crop Rotation lets you configure farm rotations and can improve yield. It is a good tool when you want to stabilize food output instead of relying on a single crop forever.

Basic farming

Basic Farming is simple potato farming. It depends on rain, so it is only a true “set and forget” option in wetter starts.

Forestry and wood planning

Harvesting options

The Forestry Control Tower lets you choose harvesting size. Full-size harvesting gives the most wood per tree, while smaller harvest sizes reduce the area needed for tree growth.

Key tradeoff:

100% gives the most wood per tree.
80% and 60% reduce the waiting time for regrowth.
40% minimizes forestry area the most, but gives the least wood.

Sizing your forestry

Forestry planning should match your assembler demand. Higher-output assembly lines require proportionally larger forestry areas. If your woodworking demand rises, expand forestry before wood shortages begin to choke construction part production.

Tree harvesting

Tree Harvester is the machine for gathering trees. It needs service trucks assigned to it, so remember to include logistics support or the harvester will sit idle.

Making coal from wood

Coal Maker converts wood into coal, but it is quite inefficient. Use it only when you need a temporary bridge or an emergency stopgap.

Production balancing and throughput

Match input and output rates

A good factory is built around matching rates, not just unlocking recipes. Production buildings do not work faster because their UI is set to 60-second display mode; that setting only makes rates easier to read. Use it to compare machines on the same time scale and design lines around clean ratios.

A practical rule is to size production chains by common divisors so both the producer and consumer run smoothly without constant buffering problems.

Overproduction and buffers

Many chains break because one step runs faster than the next. Use buffers where needed, especially for mixed or imbalanced inputs. This is especially important when startup smelting or recycling creates more recirculating material than your storage can absorb.

Recycling and waste

Recycling efficiency

Recycling Efficiency starts at 25% and can be raised to 90% through edicts and research. Higher efficiency dramatically increases how many times the same material can be reused.

At high efficiency, recycling can flood your system with recovered materials faster than they are consumed. If storage is too small, recycled goods can back up and clog production chains. Add buffers or reduce early smelting to keep the loop stable.

Recycling edicts

Recycling Edict increases the island’s overall recycling efficiency. If you want a closed-loop factory, these edicts are one of the strongest long-term upgrades.

Handling settlement waste

Waste Collection removes general waste from attached settlements so it does not pile up and cause health problems. Settlement Waste serves the same role in the broader settlement system. Do not let waste accumulate; it becomes a health issue long before it becomes an aesthetic one.

Water pollution

Use Wastewater Treatment to neutralize contaminated water streams, and a Sour Water Stripper to treat sour water before it creates pollution. Balancing byproducts and fertilizer production also helps avoid excess dumping. Proper waste handling can eliminate water pollution entirely by mid-game.

Infection and cholera

Infection is prevented by stopping trash from piling up in the settlement. Cholera spreads through contaminated water, so stable clean water supply is the primary prevention method.

Transport and logistics

Cargo docks and module mix

Cargo dock modules can be mixed and matched, but shared docks often work best when paired identically. A cargo ship will wait until it is fully unloaded before leaving, so mixing cargo types can stall departures and reduce throughput for the more important material.

Small cargo throughput

A small cargo module can outperform certain outpost extraction setups depending on the cargo and duty cycle. If your outpost is not running near full duty, one cargo module may already be enough to cover it.

Fuel stations

Fuel Station includes a toggle that controls whether non-assigned trucks may refuel there. Because only one vehicle can refuel at a time, separate refueling stations can prevent queues from blocking excavators and other critical vehicles.

Overloading trucks

Overloaded Trucks can carry more than normal, but they require extra maintenance. This is useful when you need more throughput and can afford the upkeep cost.

Amphibious vehicles

Amphibious Vehicles can operate on both land and water, but they have higher running costs than standard vehicles. Amphibious Truck and Amphibious Excavator are specialized versions of this idea. Use them when geography matters more than operating cost.

Trade and world map logistics

Trading docks

Trading Dock lets you trade goods with villages on the world map. It is worth keeping one available because trade can rescue a run when a critical resource runs short.

Food packing

Food Packing enables food to be packed for contract sales. It is a useful way to turn agricultural surplus into trade value.

Maintenance and island health

Maintenance depot

Maintenance Depot converts products into maintenance that is distributed to machines, buildings, and vehicles. If maintenance runs low, equipment can break temporarily, so this is a core support building rather than a luxury.

Custom surfaces

Custom Surfaces such as concrete reduce the maintenance needs of vehicles that drive over them. They are especially useful on busy roads and logistics corridors.

The Statue of Maintenance

The Statue of Maintenance reduces the island’s maintenance requirements, but only while it is continuously supplied with its required good. If it is left unfed, it creates a negative effect instead. You can build multiple statues, but each additional one has half the effect of the previous.

Health and population

Hospitals and diseases

Cold happens naturally and cannot be completely avoided, but its effects are greatly reduced by a hospital with medical supplies. The same principle applies to other diseases that spread through poor sanitation: clean water, waste control, and proper medical coverage matter more than reactionary fixes.

Quarantine and health boosts

Quarantine temporarily removes part of the workforce to reduce the impact of an ongoing disease. Health Boost improves safety conditions and gives extra health points. Both are strong support tools when you are trying to recover from an outbreak or stabilize a stressed colony.

Housing and Unity

[Housing II](/en/captain-of-industry/building/housing-ii) provides more comfort and can also increase monthly Unity if supported by the required services. Many social buildings work the same way: they are not just population housing, but part of your long-term Unity engine.

Consumer and household goods

Consumer Electronics Module, Household Goods, and related demand-increasing bonuses all generate extra Unity when supplied. In practice, this means social supply chains are part of your endgame economy, not optional flavor.

Beacon

[Beacon](/en/captain-of-industry/research/beacon) helps other refugees find your island and join you. More refugees means more workers and extra starting loot, so beacons are a strong early growth tool on maps where recruitment matters.

Fuel, power, and industrial energy

Steam turbine control

Turbine Control prevents a steam turbine from wasting steam by shutting it off automatically when shaft power is too high and restarting it when shaft power falls. Because restart is not instant, the shaft should have mechanical power storage for a stable supply.

High pressure turbine balancing

High Pressure Turbine II can auto-balance by idling at high shaft charge and restarting when the charge falls. As with other turbine automation, flywheels or similar storage are important if you want uninterrupted output.

Diesel, cracking, and fuel balance

Basic Diesel extracts oil reserves and converts them to diesel, but it is not very efficient. Cracking Unit converts one fuel type into another, which is useful when your fuel mix is unbalanced. These are best used as balancing tools, not as the backbone of your economy.

Flare

[Flare](/en/captain-of-industry/building/flare) can burn combustible liquids and gases, but it causes pollution. Use it only when disposal is more important than environmental cleanliness.

Arc Furnace II and advanced smelting

Arc Furnace II has higher energy requirements but can achieve higher-temperature operation and better output. Advanced smelting routes generally trade more infrastructure for better throughput and efficiency.

Industry and special projects

Using Copper Ore Crushed adds processing complexity, but it improves molten copper output and reduces unwanted byproducts. The tradeoff is additional preprocessing and filler requirements. Build this route when ore efficiency matters more than simplicity.

Microchips

Microchip Machine is one of the most advanced production chains in the game. It transforms a thin monocrystalline wafer into a layered microchip matrix using ultraviolet-based processing, with many stages including washing and coating. Start small and expand gradually; compact lines can be looped with a sorter.

Fast Breeder Reactor

A Fast Breeder Reactor needs a large startup stock of Core Fuel made the hard way, but once running it should be fed by recovered fuel and enriched blanket fuel instead of relying on fresh uranium all the time. Set your priorities so recycled material is used first and fresh enrichment only fills the gap.

Nuclear Reactor II safety

Nuclear Reactor II automatic regulation keeps power level aligned with heat demand and prevents overheating. It cannot go below the first power level, so emergency cooling is mandatory if supply or consumption can drop below that threshold.

Rocket Launch Pad

Rocket Launch Pad requires the rocket to be delivered and attached before fueling. Fuel must match the rocket type connected to the pad, and water must also be supplied because launch uses large amounts for shock suppression. The pad stores no fuel for safety.

Map tips

New Haven

New Haven is a balanced map for new and casual players. Its starting locations offer easy access to resources and enough room to build a large industrial base. It is also the first and oldest map in the game.

You Shall Not Pass

You Shall Not Pass is an expert map built around a cramped valley and a race to reach the top plateau before space and coal run out. The challenge is to exploit the upper flatlands without letting the early valley choke your expansion.

Golden Peak

Golden Peak is built around a mountain rich in gold ore, with steep terraces and uneven highlands. The key lesson is to plan excavation carefully, open access with ramps, and use dumped rock to expand buildable land.

Final practical habits

Keep water, maintenance, and waste systems ahead of growth.
Design around transport limits before expanding production.
Buffer critical inputs, especially when a chain has multiple stages.
Use trade and beacons to recover from shortages.
Expand only when the next bottleneck is already planned for.
