Starminer Beginner Guide: First Hour, Campaign Start, Mining, Heat & Defense
Starminer beginner guide for the first hour: Campaign start, starter station, power, heat, mass, mining, storage, blueprints, defenses, and what to avoid.
First-Hour Rule
Build a stable system before you build a huge one. For a first Starminer save, use Campaign, test small modules, stabilize mining and refining, leave power reserve, watch heat, and add defenses before pushing into bigger ships or new sectors. The Starminer guide hub links every follow-up once the first bottleneck appears.
First Hour Plan

| Step | Do this | Why it matters |
|---|---|---|
| 1. Pick Campaign first | Use Campaign as the first save unless you already know the building and logistics loop. | Official FAQ says Campaign missions introduce mechanics and lore, so it is the safest route into a systems-heavy sandbox. |
| 2. Build small and readable | Keep the first station compact, leave room for future modules, and avoid spreading power and logistics too thin. | Starminer links power, heat, logistics, production, and crew, so messy early layouts become expensive to diagnose. |
| 3. Stabilize mining | Create a basic asteroid extraction and refining loop before chasing distant sectors or larger ships. | Every expansion needs materials for maintenance, research, defenses, and fleet growth. |
| 4. Watch heat pressure | Treat every major expansion as a risk increase and add defenses before the heat signature reaches critical levels. | Steam explains that mining and building raise heat until aliens detect the fleet. |
| 5. Save a blueprint checkpoint | Save or recall useful designs once a build proves stable instead of rebuilding every experiment from scratch. | Blueprint save and recall is confirmed, while community sharing is planned rather than a launch guarantee. |
Choose the Right First Mode
The official FAQ lists Campaign, Sandbox, and Survival. Campaign is the right first stop for most players because it gives missions that introduce mechanics and lore. Sandbox is where you go once you know what a healthy station looks like. Survival is where you test whether the design can keep functioning under enemy pressure.
| Mode | Beginner value | When to use it |
|---|---|---|
| Campaign | Best first save for most players because it introduces core mechanics and lore through missions. | Start here if you want structure before designing freely. |
| Sandbox | Best for builders who want to customize starting conditions and chase self-made factory or fleet goals. | Start here after you understand power, heat, logistics, and defense pressure. |
| Survival | Best for players who want endless enemy waves and pressure-tested defenses. | Start here after you can build stable mining, energy, and weapon coverage. |
Build Small, Then Diagnose

Starminer combines modular construction with power, heat, logistics, production, and crew systems. That makes the first base a diagnostic tool. If everything is compact, you can see where materials stop, what runs out of power, and which modules create too much exposure. If you build too wide too early, every later problem becomes harder to trace.
Once the small layout is stable, continue into the ship building guide. It explains why mass, thrust, tonnage, and power are design questions, not just stats to maximize.
When to Stop Expanding

| Warning sign | Beginner response |
|---|---|
| Power reserve is gone | Pause expansion and add power before weapons, refining, or logistics start competing for the same capacity. |
| Materials are stuck | Fix the production chain before adding more mining modules. |
| Heat is climbing | Add defense and slow extraction before aliens or pirates turn the base into a repair bill. |
| Storage is messy | Sort resources and create clean routes before expanding to a new sector. |
| Combat coverage is thin | Protect power, refining, storage, and routes, not only the visible outer edge. |
Next Guides After the First Hour
If materials are the bottleneck, go to mining logistics. If ships feel heavy or underpowered, go to ship building. If attacks are the problem, go to heat, aliens, and defense. If you are unsure whether Campaign, Sandbox, or Survival fits your next save, use the game modes guide.

Frequently Asked Questions
Q: What should beginners do first in Starminer?
Start with Campaign, build small, stabilize a basic mining and refining loop, leave power reserve, avoid uncontrolled heat growth, and add defenses before expanding into distant sectors.
Q: Should I start Starminer in Campaign or Sandbox?
Campaign is better for a first save because the official FAQ says it introduces mechanics and lore. Sandbox is better once you understand station layout, power, logistics, and defense pressure.
Q: What is the biggest early mistake in Starminer?
The biggest early mistake is expanding faster than your power, logistics, storage, and defenses can support. Starminer rewards stable systems more than oversized first builds.
Q: When should I build defenses in Starminer?
Build defenses before the station becomes hard to protect. Steam explains that mining and building raise heat signature until aliens detect you, so defense should be part of expansion planning.
Q: Are blueprints useful for beginners?
Yes. Blueprint save and recall helps preserve stable designs. Community sharing is planned, but personal blueprint use is the safer launch-window assumption.
