Resources and limits
| Resource group | Contents | Used for |
|---|---|---|
| Basic | Iron, Copper, Lithium | Early buildings, factories, and units |
| Manufactured | Iron Plate, Alloy, PV Cell | Construction and upgrades |
| Rare | Titanium, Iridium, Kimberlite, Platinum | Advanced buildings and unit upgrades |
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 produce one resource while active and stop accumulating it when storage is full.
| 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 an Iridium motherlode asteroid |
 Kimberlite Mine |
 Kimberlite |
Only on a Kimberlite motherlode asteroid |
 Platinum Mine |
 Platinum |
Only on a Platinum motherlode asteroid |
Upgrade a mine to raise its output. Mines need no input resources and keep producing while you are away. Your Main Base level limits their upgrades.
Factories and production
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 consume your colony's stockpile. If consumption exceeds mining output, that basic resource runs down. Check the rates in the factory panel.
Production is shown as an estimate until claimed. Use Claim if a completed production or training balance has not updated.

Building availability depends on the asteroid and your Main Base level. Select a building to see its cost, footprint, and requirements.
Placement and upgrading
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.
Blueprints → choose a mine → select a free mineral deposit → confirm placement. Wait for the built mine to appear.
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
- Select an active Workshop, Drone Factory, or Shipyard.
- Choose an unlocked unit and quantity. Check its cost, housing, and training time.
- Start training. The order pays its resource cost and reserves housing immediately.
- Collect finished units. Units complete one at a time, so part of an order may be ready while the rest is still training.
- 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
Need Titanium, Iridium, Kimberlite, or Platinum? Buy it, raid it, or mine it.
| Method | What to do |
|---|---|
| Buy | Select your Market, choose the resource and amount, review the exchange quote, then confirm. |
| Raid | Send combat units without a Colony Ship to an asteroid holding the resource. Win the attack, return home, and unload the loot. Leave cargo space; Vaults protect some resources. |
| Mine | Find a matching motherlode in Starbelt. Capture it with a Colony Ship and combat units, then build the matching rare mine. A Titanium Mine needs a Titanium motherlode, for example. |
For a steady supply, capture and defend a motherlode. See how to capture an asteroid or how to raid.
Objectives and rewards
Objectives → complete the requirement → Claim. Rewards are not collected automatically.
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.
