Resources and limits

Storage limits apply to each resource. An empty Copper store does not make room for more Iron.

Electricity, housing, and fleet capacity are separate limits. Solar Panels supply electricity; Garages and Hangars add housing; the Starmapper adds fleet capacity. You cannot load these utilities as cargo.

Mines

Mines are the first buildings you place and the base of every other chain. Each mine produces one resource continuously while it is active, and the colony's storage limit for that resource caps what it can accumulate.

Mine	Produces	Where it can be built
Iron Mine	Iron	An unoccupied mineral-deposit tile inside your unlocked area
Copper Mine	Copper	An unoccupied mineral-deposit tile inside your unlocked area
Lithium Mine	Lithium	An unoccupied mineral-deposit tile inside your unlocked area
Titanium Mine	Titanium	Only on a Titanium motherlode asteroid
Iridium Mine	Iridium	Only on a Iridium motherlode asteroid
Kimberlite Mine	Kimberlite	Only on a Kimberlite motherlode asteroid
Platinum Mine	Platinum	Only on a Platinum motherlode asteroid

Upgrading a mine raises its output; the first three objectives after the social ones ask you to upgrade each basic mine to level 2. Mines have no input: they keep producing while you are away, and the resource display estimates what they have produced since your last claim. The number of mines is limited only by the room inside your unlocked area and by your Main Base level, which gates higher mine levels.

Factories and production

Iron→Iron Plate Factory→Iron Plate

Copper→Alloy Factory→Alloy

Lithium→PV Cell Factory→PV Cell

Factories consume the colony’s basic resources. Check both production and consumption before adding another factory.

The three factory chains are:

Factory	Basic resource used	Output
Iron Plate Factory	Iron	Iron Plate
Alloy Factory	Copper	Alloy
PV Cell Factory	Lithium	PV Cell

Factories draw on the same stockpile you use to build and train. Compare production with consumption: if Copper use exceeds Copper production, your stored Copper falls even while the mines are running. Check the factory panel for its current rates.

The resource display estimates what you have produced since the last update. A claim, or a game action that includes one, records that production. Completed training works similarly. If a displayed total is ahead of the stored balance, use the claim control and let the game refresh.

Vault	Protects some stored resources from raids
Market	Exchanges resources at the quoted rate
Wormhole Base	Accepts resource deposits for points

Building availability depends on the asteroid and your Main Base level. Select a building to see its cost, footprint, and requirements.

Placement and upgrading

12

Iron, Copper, and Lithium Mines must be placed on mineral-deposit tiles. All three use the same required terrain type; an empty patch of ground is not enough.

Select the mine from Blueprints, position it over an unoccupied mineral deposit inside your unlocked area, and check that placement is allowed before clicking. Wait for the transaction result and the built mine to appear before treating it as complete.

The entire building must fit inside your unlocked area, avoid occupied tiles, and meet its terrain requirement. Expand from the Main Base when you need more room.

Building upgrades and unit upgrades are separate purchases. Upgrading a Workshop can improve training or unlock another unit; it does not buy that unit's upgrade. Unit upgrades apply to that unit type on the selected asteroid and fleets based there.

Training units

1. Select an active Workshop, Drone Factory, or Shipyard.
2. Choose an unlocked unit and quantity. Check its cost, housing, and training time.
3. Start training. The order pays its resource cost and reserves housing immediately.
4. Collect finished units. Units complete one at a time, so part of an order may be ready while the rest is still training.
5. Transfer them into a fleet when you want to send them elsewhere.

A Shipyard can have only one Colony Ship training order at a time. Colony Ships also need a free colony slot; see conquest.

Getting rare resources

You have three routes: raid an asteroid with the resources you need, capture a suitable asteroid and build its rare mine, or buy resources through the Market. Mining gives you a continuing supply, but the colony needs defending. A Market trade can be quicker; check its quoted output and fees before confirming. Original game guide

Objectives and rewards

Objectives give you specific tasks and rewards. Open an objective to see what it requires and what you receive. Completing the task and claiming the reward are separate steps.

Leave room for the reward in storage or housing. Some objectives need a particular action or battle record; an existing balance or army may not satisfy them. If the claim is blocked, check the missing requirement shown in the objective.

Continue with fleets and conquest.
