- subterra guide: Start with the surface loop, then scale into deeper mining only after upgrades feel efficient.
- Best early priority: Upgrade pickaxe power first, then backpack space, then Ability Cards and crafting.
- Safer progress: Use layers, ores, and enemy risk to choose routes instead of tunneling straight down.
- Best economy habit: Keep rare materials for recipes and spend common ores on steady progression.
Subterra Guide: Core Loop and Official Links
Subterra is a fast progression mining game, and the best opening move is to learn the loop before you chase deeper layers. Mine, sell, upgrade, and repeat. That rhythm keeps your inventory clean and your early runs profitable.
- Focus on mine → sell → upgrade until your routes feel stable.
- Treat the surface lobby as your reset point between longer runs.
- Use the official game page and Trello for current systems and references.
- Save rare materials for recipes that actually move progression forward.

| Upgrade tools | Raises mining speed and power | Opens tougher layers faster |
| Spend shards carefully | Improves long-term build quality | Prevents waste on low-value pulls |
First 30 Minutes: Set Up a Clean Mining Route
Your first half hour should feel disciplined, not random. Complete the opening flow, learn the controls, and leave each run with a clear goal. If you always know what material you are hunting next, progression becomes much smoother.
If your backpack fills before your target list is done, return to the surface, sell, and upgrade before going back down.
Finish the tutorial and reach the lobby
Unlock full movement, locate the spawn area, and learn where the upgrade, sell, and code NPCs sit.
Learn the key inputs
Open inventory with E, interact with C, block or parry with F, and mine with the left mouse button.
Farm the first resource band
Gather rocks, coal, copper, and tin before you worry about rare gems or deep-layer materials.
Sell early and upgrade once
Turn surplus loot into Gold, then buy the first useful pickaxe or backpack tier that improves your next run.
Set one short-term target
Pick a single goal for the next trip, such as a material stack, a code reward, or a backpack upgrade.
| Time Window | Focus | Stop When |
|---|---|---|
| 0-10 min | Learn controls, lobby flow, and NPC locations | You can move, interact, and mine without hesitation |
| 10-20 min | Gather early ores and basic materials | Inventory starts getting close to full |
| 20-30 min | Sell, upgrade, and return with a better route | Your next run has a clearer material target |
Upgrades: Pickaxe, Backpack, and Card Priority
Early Subterra progress is mostly about spending the right materials at the right time. Pickaxe upgrades improve mining power and speed, while backpack upgrades prevent short trips from killing momentum. Ability Cards then push your route efficiency even further.
Do not burn rare gems or midgame ingots on side upgrades if they are listed in a later recipe. A delayed upgrade is usually better than a dead-end purchase.
Pickaxe First
- More power
- Faster block breaks
- Better depth access
Backpack Second
- More carry space
- Fewer return trips
- Better loot efficiency
Chrono Shards
- Card progression
- Long-term build value
- Stronger utility scaling
Crafting Later
- Use spare materials
- Make weapons and consumables
- Avoid progress bottlenecks
| Upgrade | Early Trigger | Why Buy It |
|---|---|---|
| Pickaxe Tier 2 | When the starter tool feels slow | First practical boost for surface mining |
| Pickaxe Tier 6 | When Tin and Copper Ingots become steady | Big jump in power and speed |
| Backpack Tier 2 | When trips end too early | More room for beginner mining loops |
| Backpack Tier 5 | When Silver and gems become common | Better midgame storage efficiency |
| Ability Cards | When Chrono Shards start stacking up | Adds mining, mobility, or survival value |
| Material | Hold For | Reason |
|---|---|---|
| Citrine, Topaz, Amethyst | Later upgrade recipes | Often needed in higher tiers |
| Emerald, Ruby, Sapphire | Backpack and progression recipes | Easy to waste, hard to replace |
| Diamond | High-value late use | Strong candidate for saving |
| Coal, Copper, Tin | Early upgrade chain | Best used to smooth the early loop |
Layers, Ores, and Risk by Depth
The safest way to move deeper is to treat each layer as a separate job. Know the ore band, know the threat level, and know what you are there to take home. That approach keeps the run focused and protects your profit margin.
Move down only when the current layer stops paying for itself. If a lower zone increases deaths more than rewards, you are there too early.
| Layer | Depth | Key Ores | Main Threat | Best Objective |
|---|---|---|---|---|
| Overworld | Surface hub | None | Minimal | Buy, sell, craft, and prep |
| Dirt Layer | Surface to around Y -35 | Coal, Copper, Tin | Slime, Zombie | Build your first material stock |
| Stone Layer | Starts around Y -35 | Iron, Silver, Gold, gems | Slime, Zombie, Bomb Skeleton | Farm the first real progression ores |
| Darkstone Layer | Starts around Y -435 | Cobalt, Nocturnite, Black Ice | Darkstone Skeleton | Push into deeper value routes |
| Permafrost Layer | Starts around Y -723 | Chromium, Moonstone, Sunstone, Titanium | Ice Slime, Ice Elemental | Farm advanced ores and crystals |
| Schwarzfrost Layer | Deep frozen endgame | Charged Ice, Eiskron, Nocturnite | High-end enemies and boss pressure | Prepare for boss routes and top-tier loot |
| Resource Type | Best Use | Keep or Sell |
|---|---|---|
| Common ores | Early upgrades and currency | Sell some, keep some |
| Gem drops | Recipe and tier progression | Usually keep |
| Deep crystals | Late crafting and strong recipes | Keep |
| Loot from chests | Keys, scrolls, and consumables | Keep until reviewed |
The key habit is simple: mine a layer for its value, not just its depth. If a zone gives better materials but slows your route too much, return later with stronger gear.
Best Loadouts and Crafting Rules
A good loadout in Subterra is not only about damage. It is about how long you can stay underground, how fast you can clear blocks, and how safely you can leave with profit.
One strong weapon plus a focused card set usually beats a messy build with random bonuses.
Miner Build
- Lucky
- Bigger Backpack
- Blazing Pickaxe
- Best for ore farming and long mining loops
Safety Build
- Healthy
- Double Jump
- Walk Speed
- Best for survival, escape routes, and vertical caves
Combat Build
- Splitblade
- Explosive Touch
- Larger Furnace
- Best for hostile layers and boss prep
| Loadout | Best For | Tradeoff |
|---|---|---|
| Miner | Ore farming and faster returns | Less direct combat pressure |
| Safety | Exploration and mistake recovery | Lower raw farming speed |
| Combat | Boss routes and enemy-heavy layers | More resource hungry |
| Crafting Priority | Good Use | Notes |
|---|---|---|
| Small Health Potion | Early survival | Great when deeper runs start to sting |
| Sticky explosives | Controlled clearing | Best for dense blocks and ore pockets |
| Keys | Chest access | Hold onto them until you find a worthwhile chest |
| Weapons | Enemy control | Craft before hostile layers punish you |
Build around the route you actually run. If you mostly mine, keep ore and carry bonuses high. If you keep dying in deeper caves, shift slots toward mobility and health before chasing more damage.
Checklist and FAQ
Before you push into a deeper run, make sure the basics are handled. This final pass keeps your progression clean and makes every session more predictable.
If a run feels messy, reset at the lobby instead of forcing a bad push. Clean decisions save more time than desperate mining.
Before Your Next Run:
- Sell excess loot before your backpack gets trapped on junk
- Confirm your next pickaxe or backpack upgrade target
- Keep rare gems reserved for future recipes
- Bring a weapon that matches the layer danger
- Use Ability Cards that support your real playstyle
| Common Mistake | Better Habit |
|---|---|
| Rushing deep layers too early | Farm the current layer until it pays back the trip |
| Spending rare gems immediately | Hold them for upgrade recipes |
| Ignoring backpack limits | Upgrade storage as soon as trips get inefficient |
| Mixing random cards | Build around one clear role |
Q: What is the best first goal in this subterra guide?
Start with a stable mine-and-sell loop, then buy the first meaningful pickaxe or backpack upgrade before chasing deeper layers.
Q: Should I upgrade pickaxe or backpack first?
Pickaxe first in most cases. Backpack comes next when your trips end too early and you are leaving value behind.
Q: When should I start saving rare gems?
Save them as soon as they appear in upgrade or crafting recipes. Diamonds, Ruby, Sapphire, Emerald, and similar materials are easy to regret spending early.
Q: What kind of build works best for long runs?
A miner-focused build with Lucky, Bigger Backpack, and Blazing Pickaxe is strong for long ore routes, while Healthy and mobility cards help when survival becomes the main issue.
