- Subterra Guardians rewards a simple loop: mine, sell, upgrade, and push deeper.
- Redeem active codes early for Chrono Shards, TNT, EXP boosts, and potions.
- Upgrade your pickaxe first so every mining run clears blocks faster.
- Use Ability Cards to scale mining speed, carry space, and survival.
- Match your layer with the right weapon, mobility, and healing setup.
Subterra Guardians Start Route
Subterra Guardians works best when you treat the first hour like a setup run, not a sprint into danger. The early game is about building a profit loop: mine useful blocks, sell often, then reinvest into power, space, and safer routes.
Mine First
- Rock, Coal, Copper
- Keep inventory space open
- Return when value drops
Upgrade First
- Pickaxe power
- Faster block breaks
- Smoother layer progression
Recover Smart
- Sell before overfilling
- Bring healing for deeper runs
- Reset at the surface lobby
If your bag fills before the route ends, the route is too long for your current gear. Short runs with steady upgrades beat risky overextends.
| Priority | Focus | Why It Matters | What to Do |
|---|---|---|---|
| 1 | Mine common materials | Early money and upgrade fuel | Clear Rock, Coal, and Copper before chasing rare veins |
| 2 | Sell regularly | Keeps the loop efficient | Return to the surface before your bag is clogged |
| 3 | Upgrade pickaxe | Faster mining and deeper access | Spend on power before comfort items |
| 4 | Expand backpack | Longer runs and fewer resets | Buy space once trips end too early |
Finish the tutorial
Unlock the surface lobby, learn the layout, and use the lobby as your safe reset point.
Mine and bank early resources
Focus on the basic ore route, then sell before your inventory becomes the bottleneck.
Buy the first upgrade path
Spend on pickaxe strength first, then backpack space once mining trips start ending too soon.
Push only when the route stays profitable
Move deeper after your gear, healing, and inventory can handle longer runs.
Keep one goal per trip: upgrade money, card currency, or deeper-layer materials. Mixing all three usually slows progress.
Codes and Official Links
Codes are the fastest way to accelerate early progress, especially when you want Chrono Shards for card growth or EXP boosts for faster leveling. Redeem them from the surface lobby before you commit to a long mining session.
Code rewards can shift over time, so claim them early and use the rewards where they matter most: progression, survivability, and route speed.

Open Subterra
Launch the Roblox experience and finish the opening tutorial.
Reach the surface lobby
Stay near the spawn gate area where the Codes NPC is located.
Enter one code at a time
Type a working code carefully, then press Claim Code before moving to the next one.
Spend rewards with intent
Use Chrono Shards on card growth and save boosts for longer play sessions.
If you only have time for one reward type, start with Chrono Shards. They support long-term growth better than short-term convenience.
Upgrades and Ability Cards
The strongest Subterra runs usually combine one clear mining upgrade path with a card setup that supports the same goal. Pickaxe upgrades improve speed and power, backpack upgrades reduce return trips, and cards shape the way each run feels.
Ore Farmer
- Lucky
- Explosive Touch
- Blazing Pickaxe
- Best for dense ore routes
Safe Explorer
- Double Jump
- Walk Speed
- Extra Oxygen
- Best for vertical and long routes
Carry & Smelt
- Bigger Backpack
- Pouch
- Larger Furnace
- Best for long sell loops
Let the route decide the loadout. Mining-heavy sessions want ore value and speed, while deep exploration needs mobility and survival.
| System | Best Early Target | Benefit | Delay Risk |
|---|---|---|---|
| Pickaxe | Power and speed | Faster mining, better block handling | Slower route clears |
| Backpack | Space increase | Longer runs, fewer exits | Inventory fills too early |
| Ability Cards | Lucky, Bigger Backpack, Walk Speed | Direct run efficiency | Wasted Chrono Shards on the wrong setup |
| Crafting | Weapons and utility items | Better combat and deeper exploration | Weak defense in hostile layers |
| Card | Rarity | Limit | Why It Matters |
|---|---|---|---|
| Lucky | Rare | 3 | Chance to double ore gains |
| Explosive Touch | Legendary | 2 | Clears clustered blocks faster |
| Blazing Pickaxe | Legendary | 2 | Automatically smelts some mined ore |
| Bigger Backpack | Rare | 5 | More inventory space for long runs |
| Healthy | Uncommon | 10 | Extra HP for deeper layers |
Do not spend rare materials too freely. Gems and ingot chains often appear in later recipes, so saving them can prevent a midgame slowdown.
Layers, Ores, and Threats
Subterra gets harsher as you descend, but the reward curve rises with it. Each layer changes the ore pool, enemy pressure, and the kind of gear you should carry. If you want steady progress, think in terms of route safety first, damage second, and greed last.
Deeper layers usually mean better ore and better loot, but they also punish weak weapons, thin healing, and poor mobility.
| Layer | Typical Depth | Main Resources | Best Goal |
|---|---|---|---|
| Overworld | Surface hub | Shop items, Smeltery, Sell Area, Crafting Altar, Portal | Prepare, craft, sell |
| Dirt Layer | Surface to around Y -35 | Dirt, Stone, Rock, Roots, Coal, Copper, Tin | Early farming |
| Stone Layer | Starts around Y -35 | Iron, Silver, Gold, gems, Platinum, Diamond | Midgame progression |
| Darkstone Layer | Starts around Y -435 | Cobalt, Nocturnite, Black Ice, deep ore pockets | First major deep push |
| Permafrost Layer | Starts around Y -723 | Chromium, Moonstone, Sunstone, Titanium, Wolframite | Advanced farming |
| Schwarzfrost Layer | Below Permafrost | Charged Ice, Eiskron, boss-route loot | Endgame pressure |
| Enemy or Boss | Layer | Threat Level | Counter |
|---|---|---|---|
| Zombie | Dirt, Stone | Low to moderate | Keep space and avoid crowd fights |
| Slime | Dirt, Stone | Low to moderate | Use early melee timing and basic spacing |
| Bomb Skeleton | Stone | High | Back up before the bomb timer becomes a problem |
| Darkstone Skeleton | Darkstone, Permafrost | High | Bring stronger weapons and mobility cards |
| Ice Elemental | Permafrost | Very high | Use healing, distance, and a solid damage weapon |
| Yrsa of the Sunken Seas | Schwarzfrost | Boss-level | Enter with a high-damage loadout and recovery items |
| Ore Tier | Example Resources | Good Use |
|---|---|---|
| Early | Coal, Copper, Tin | First upgrades and basic crafting |
| Mid | Iron, Silver, Gold | Better tools, keys, and economy |
| Advanced | Platinum, Cobalt, Chromium | Deeper upgrades and stronger routes |
| High Value | Titanium, Wolframite, Nocturnite | Late-game progression and selling |
| Gem Route | Topaz, Amethyst, Emerald, Ruby, Sapphire, Diamond | Quest goals and recipe storage |
Move layer by layer instead of tunneling blindly. That approach keeps your ore income predictable and your death risk lower.
Checklist and FAQ
Use this final pass before any long mining session. A clean checklist keeps the run profitable and makes deeper pushes much safer.
Treat this as your pre-run reset: check gear, check healing, check cards, then go deeper only if the route still pays.
Before You Head Down:
- Redeem the current codes and spend rewards with intent
- Upgrade the pickaxe before buying comfort upgrades
- Keep backpack space open for high-value ores
- Bring a survival card set for long or deep runs
- Carry healing before Darkstone or Permafrost pushes
Q: What should I upgrade first in Subterra Guardians?
Start with the pickaxe. It improves mining speed and power, which makes every later upgrade easier to afford.
Q: Are the active codes worth redeeming early?
Yes. Chrono Shards, EXP boosts, TNT, and potions all help the early game feel smoother and faster.
Q: When should I move to deeper layers?
Move down when your gear clears blocks efficiently, your healing is stable, and your returns still make profit.
Q: Which cards are best for general runs?
Lucky, Bigger Backpack, Walk Speed, and Blazing Pickaxe cover most mining-focused routes very well.
Subterra Guardians rewards organized progression. If you mine smart, upgrade in the right order, and match your build to the layer, the game stays efficient instead of chaotic.
