Stars Reach Mining and Terraforming
Extract with the Terraformer, manage hoppers and tailings, avoid cave-ins, and shape worlds on purpose.
Mining is world-making
In Stars Reach by Playable Worlds, digging is never only inventory filler. The Terraformer family lets you extract minerals, scan at range, deposit matter, and reshape terrain. That means every mine is also an edit to a living planet—especially once you leave Haven’s teaching spaces for Crucible and beyond. Steam Early Access arrives August 18, 2026 (AppID 1925650); expect tool splits, hopper rules, and scan ranges to keep evolving.
If you are brand new, finish Getting Started first. For binds, keep Controls handy: TAB selects resources, meters on the reticle track hoppers and batteries, and grappler R saves you from your own pits.
The Terraformer tool family
Playtests split an overloaded multi-tool into clearer jobs:
- Terraformer — primary extraction and active resource scanning
- Depositor — places chosen resources from inventory back into the world
- Chronophaser — heat beam plus erode / lithify style operations for reshaping matter
Related harvesting tools handle organics and planting flows, also using TAB when you must pick a seed or resource type. Starter tools exist so every profession can begin, but crafted upgrades matter—PQRV on your Terraformer changes how pleasant mining feels. Feed upgrades through the Crafting Guide.
Scanning before you dig
Long-range mineral and gem prospecting exists so you stop treating every hillside like a lottery. Scan, mark a target mentally, then commit a tunnel plan. Blind digging wastes durability, battery, and structural integrity.
Cross-check what you find against resources and rarity and the wider systems pages. Planet identity matters: Haven teaches; Crucible pressures; later worlds in planets & exploration change which signatures are worth a long trip.
Hoppers, tailings, and inventory discipline
When you extract, material flows into a hopper. Fill behavior is tutorialized the first time for a reason—overflow thinking differs from classic MMO bags. Tailings eject as waste byproducts rather than pretending every pixel is treasure. Plan drop points, depositor cleanups, and trips back to camp so you are not stranded heavy and slow.
Practical habits:
- Select the intended resource with TAB before the beam starts singing.
- Watch hopper meters; leave margin for a grappler escape.
- Separate “keep for crafting” piles from “reshape later” piles.
- Craft interim components soon so raw stock does not rot your motivation.
Cave-ins and structural respect
Sandbox voxels forgive creativity until they do not. Undercutting wide chambers, deleting pillars, or heat-blasting support rock invites collapse. Dig with future-you in mind: leave ribs, avoid hairline exits, and keep an upward escape that a grappler can finish.
If you are mining under a place you might later settle, read Building Settlements before you cheese the crust into Swiss cheese. Terrain under a homestead is not free money—it is foundation.
Chronophaser: heat, erode, lithify
The Chronophaser is how mining becomes terraforming art. Heat beams and erode/lithify operations let you harden, soften, or reshape volumes that pure extraction would only delete. Use it to open safe galleries, sculpt roads toward a camp, or clean a cliff face for building tiles.
It is still a tool with costs and skill-tree ties. XP flows when you use the associated actions—see How to Play for the useful-action philosophy and skill trees for how mining-facing nodes unlock specials you can bind to E/Q.
Civil Engineering versus smash tunnels
Not every hole is a mine. Civil Engineering style play treats tunnels as infrastructure: graded paths, support-minded corridors, access to fabricators, and logistics for groups. Smash tunnels maximize short-term ore and externalize collapse risk to whoever walks through next.
Early Access communities will develop etiquette around shared planets. If you dig public routes near hubs or popular Crucible sites, engineer them. If you claim a private shaft toward a rare vein, still leave yourself a maintainable bore instead of a death maze.
Compare goals:
| Goal | Approach |
|---|---|
| Fast sample of a vein | Narrow bore, frequent scans, quick extract |
| Long-term claim | Supported galleries, marked exits, depositor cleanup |
| Settlement prep | Chronophaser grading, flat pads, controlled fill |
| Group logistics | Wider corridors, pullouts, camp adjacency |
Linking mining to economy and skills
Raw ore is only half a product. Refining and metallurgy turn scans into tradable goods and better tools. When your hopper habits stabilize, push materials through crafting chains and consider vendor outlets described in economy & trading.
Skill investment should match your week: deepen mining nodes while you chase a tool breakpoint, then atrophy lower priorities using respec in practice when you pivot to crafting or settlement work. Profession framing lives under professions and the skills hub.
Session plan for new miners
- From a camp or Starbase, confirm tool durability and empty hopper space.
- Travel with grappler confidence and a return route.
- Scan first; dig second.
- Extract a focused resource list for a known recipe.
- Deposit waste thoughtfully; do not landfill a future plaza.
- Bank at camp; craft the next upgrade the same evening if you can.

Mine like a surveyor and a civil engineer, not like a loot pinata. The Terraformer rewards players who treat planets as workshops—and who still remember to leave a pillar.
Frequently Asked Questions
Quick answers to the most common questions.
What does the Terraformer do?
It is the primary tool for extracting minerals and actively scanning for resources. Related tools handle depositing and Chronophaser heat or erode operations.
How do hoppers and tailings work?
Extracted material fills your hopper while waste ejects as tailings. Manage capacity, drop intentional piles, and return to camp before you are overencumbered.
How do I avoid cave-ins?
Leave supports, avoid reckless undercuts, keep escape routes, and use Chronophaser shaping when you need stable galleries instead of hollowed crust.
What is the difference between mining tunnels and Civil Engineering?
Mining tunnels chase ore efficiently; Civil Engineering treats passages as lasting infrastructure with grades, supports, and settlement access in mind.
Where do mined materials go next?
Into refining and PQRV crafting chains for better tools and trade goods—see the Crafting Guide and economy pages.
