Starter Guide

Subterra Beginner Guide

Learn the basic loop: mine resources, manage inventory, upgrade your pickaxe and backpack, build with Ability Cards, craft gear, and survive deeper layers.

Subterra is a 2.5D mining adventure where the world is procedurally generated and the layers become more hostile as you dig deeper. The clean starter route is simple: learn the controls, mine ores, upgrade tools, add Ability Cards, craft weapons or potions, then push into deeper layers while keeping each run profitable.

Step 1

Complete the Tutorial and Reach the Surface Lobby

Goal: Unlock free movement and learn where key NPCs and gates are located.

  • Finish the opening tutorial.
  • Locate the spawn gate area.
  • Find the Codes NPC for reward redemption.
  • Use the lobby as your reset point before deeper mining runs.
Step 2

Learn the Core Controls

Goal: Move, mine, interact, block, and manage inventory without losing time underground.

  • EOpen Inventory
  • CInteract
  • FBlock or Parry
  • Left MouseMine
Step 3

Mine Ores and Track Your Next Upgrade

Goal: Collect the materials needed for stronger pickaxes and larger backpacks.

  • Use Left Mouse to mine blocks and ores.
  • Prioritize materials required by your next pickaxe or backpack tier.
  • Keep inventory space open for valuable ores.
  • Return to the surface when your bag is full or your run becomes risky.
Step 4

Upgrade Pickaxe First, Backpack Second

Goal: Improve mining power and speed before pushing too deep.

  • Upgrade your pickaxe to mine faster and handle tougher layers.
  • Upgrade your backpack when short inventory runs start slowing progress.
  • Use early Gold, Rock, Coal, Copper, Tin, and Ingots for the first upgrade chain.
Step 5

Build Around Ability Cards

Goal: Use Ability Cards to shape your mining and survival style.

  • Spend Chrono Shards on card progression.
  • Equip cards that improve your run efficiency.
  • Use code rewards to speed up early card access.
Step 6

Craft Weapons, Potions, and Recipes

Goal: Prepare for monsters, bosses, and longer underground runs.

  • Craft weapons to fight enemies below the surface.
  • Look for rare weapon and potion recipes.
  • Use consumables before longer mining pushes.
Step 7

Explore Layers and Structures

Goal: Find deeper resources, lootable chests, cave structures, and progression materials.

  • Move layer by layer instead of rushing straight down.
  • Open chests and inspect structures when safe.
  • Watch for stronger monsters as the depth increases.
Step 8

Fight Carefully and Use Block or Parry

Goal: Survive hostile layers while keeping mining runs profitable.

  • Use F to block or parry incoming attacks.
  • Keep weapons ready when entering hostile sections.
  • Retreat when enemies or bosses make the run too expensive.
Progression

Subterra Pickaxe and Backpack Upgrades

Plan early Subterra progression with pickaxe power, mining speed, backpack space, and upgrade recipes.

Pickaxe upgrades raise your mining power and speed, while backpack upgrades increase inventory space. The first stretch is where materials are easiest to misallocate, so use the tier data below before spending.

Upgrade Priority

#1Upgrade Pickaxe When Mining Feels Slow

Pickaxe tiers increase both power and mining speed, so they unlock faster routes through tougher blocks and deeper layers.

#2Upgrade Backpack When Trips End Too Early

Backpack upgrades are best when your inventory fills before your mining route is finished.

#3Save Gems for Required Recipes

Citrine, Topaz, Amethyst, Emerald, Ruby, Sapphire, and Diamond appear in upgrade recipes, so spending them early can delay later tiers.

#4Use Codes to Accelerate Card and EXP Progress

Chrono Shards, TNT Blocks, EXP boosts, and potions support the same mining loop that feeds pickaxe and backpack progression.

Weapons & Cards

Subterra Weapons and Ability Cards Tier List

Compare Subterra weapons and Ability Cards by damage, rarity, card limit, utility, and stage fit. This ranking is built for practical progression, mining efficiency, combat safety, and deeper-layer exploration.

Combat and mining builds depend on both weapon choice and Ability Card stacking. High-value setups usually combine one reliable weapon with cards that improve ore yield, pickaxe speed, backpack space, mobility, or survival in hostile layers.

Tier letters rank overall progression value. Weapons are measured by damage and recipe tier; Ability Cards are measured by effect strength, card limit, and how broadly the effect improves a mining or combat route.

Crafting & Materials

Subterra Crafting Recipes and Materials

Track useful recipes, potion ingredients, explosive upgrades, keys, ore materials, ingots, crystals, and common resource sources. This table is built for quick filtering by crafting type, material source, and progression use.

Crafting connects mining, monster drops, recipe scrolls, smelting, keys, potions, and explosives. Prioritize health recovery, chest access, sticky explosives, and ingot production because those systems directly affect exploration speed and deeper-layer survival.

Layers & Exploration

Subterra Layers Ores and Structures

Explore by layer, ore tier, structure type, portal access, and resource value. This module helps players decide where to mine, what to look for, and when to push deeper.

The world becomes more dangerous as players descend through procedural cave layers. Each layer changes the block pool, ore value, structures, enemies, and exploration goals, so a strong route balances pickaxe upgrades, oxygen, weapons, keys, and inventory space.

Depth values reflect common progression breaks. Portal coordinates mark fast-travel unlocks; layers without a listed portal are reached by mining downward from the layer above.

Track monsters, bosses, drops, quests, titles, and achievement rewards from early mining goals to deep-layer boss progression.

Progression is not just mining downward. Monsters pressure cave routes, bosses guard deeper milestones, quests provide Gold and EXP, and achievements reward Chrono Shards for mining, chest hunting, exploration, and combat milestones.
