Some route advice comes from high-quality community documentation rather than official numerical data. The game does not publish a complete drop-rate table, so recommendations are practical priorities, not guaranteed yields.
Fast answer
The answer before the background
To farm efficiently, enter a cave, push to its far end, mine valuable deposits while moving back toward the Robospider, and vacuum everything only after you have created a short return path. In the base game, mine the material needed for your next upgrade rather than chasing a universal gold currency. Diamonds, emeralds, amethysts, ceramic crystals, hyper cells, red quartz, bismuth, processors, and other zone materials are tied to particular biomes. For permanent progress, harder caves generally give more upgrade value. In Deep Threat, treat gold and the later DLC materials as separate, scarce resources: clear the biome that contains them before moving on, because the same material may stop appearing after a transition.
What you are actually farming
There is no standard coin economy
The phrase “coins” is useful as a search term, but the original game is built around mined materials and a permanent-upgrade resource rather than a shop full of spendable coins. Mining deposits during a run advances your long-term upgrade economy, while the physical materials you carry back are spent on weapons, equipment, exosuit upgrades, repairs, and other run progression.
That distinction matters because a route that produces many common materials can still be worse than a shorter route that finds the one material blocking your next upgrade. Treat every run as two farms at once: a permanent-progression farm and a targeted material farm.
- Permanent progression: mine as much as safely possible, with harder areas generally offering more value.
- Run upgrades: collect the material required by the weapon, module, exosuit, or repair option you want next.
- Anomalies: search side passages for weapons, equipment, blueprints, and other one-off rewards when the wave timer allows it.
| Resource or group | Typical role | Best farming approach |
|---|---|---|
| Permanent-upgrade resource | Long-term progression outside the immediate run | Mine consistently rather than abandoning low-risk deposits. |
| Common early materials | Basic upgrades and repairs | Collect them while travelling toward a higher-priority deposit. |
| Biome-specific materials | Advanced weapon, equipment, or exosuit upgrades | Route through the matching biome when an upgrade requires them. |
| Blueprints and relics | Permanent or run-specific unlocks | Check unusual rooms and side tunnels instead of only mining the main corridor. |
The game references confirm mining, upgrades, biomes, relics, and blueprints. Exact value-per-node figures and universal best-per-minute routes are not published consistently, so efficiency comparisons below are recommendations rather than fixed game rules.
Base game
Use the zone map to target materials
The base game places resource families in recognizable biome bands. The commonly documented route runs from the starting rocky area into upper and lower zones, with each deeper or higher biome introducing a different material family. Some caves can contain a lower-tier biome than expected, so do not assume every node in a zone has the exact same contents.
A practical material route is to collect enough early resources for your mining tool, then prioritize the next biome material required by your intended build. If you are not chasing a specific upgrade, continue clearing safe caves in the starter area before taking a risky transition. This produces a steadier permanent-progression return and gives you more time to find equipment anomalies.
- Rocky caves: diamonds are the commonly documented material for the starting area.
- Mossy or jungle-style caves: emeralds are associated with repairs and some advanced upgrades.
- Ice or frozen caves: ceramic crystals and related high-tier materials support advanced upgrades.
- Lower blood or flesh-like caves: hyper cells are used for powerful upgrades and can also support repairs.
- Molten or volcanic caves: red quartz and obsidian-type materials are late-progression resources.
- Upper refracting or cubic-style caves: bismuth, processors, or equivalent high-tier materials are associated with advanced technology.
| Goal | Recommended route | Why it works |
|---|---|---|
| Steady early progression | Clear starter caves, then take the easiest useful transition | You build permanent value without overcommitting to dangerous mining. |
| A specific weapon upgrade | Identify its required material, then revisit the matching biome | Targeted farming prevents a run from filling with materials you cannot spend. |
| Maximum haul before a wave | Mine to the far end, then vacuum on the return trip | This reduces backtracking and keeps dropped resources closer to the spider. |
| Blueprint hunting | Search side tunnels and special rooms after securing the main deposits | Blueprints and anomalies can be more valuable than another pocket of common ore. |
Diamonds are useful, but they are not a universal currency. If your next upgrade needs a higher-tier biome material, spending the whole run in early diamond caves can delay the upgrade you actually want.
Repeatable loop
A reliable farming cycle between enemy waves
The strongest repeatable loop is built around short, deliberate cave trips. Start by checking the wave timer and your current upgrade target. Enter the cave with enough time to reach the far side, mine the densest or most valuable deposits first, and leave a clear return route. Vacuum on the way back rather than repeatedly carrying small groups from the same spot.
If a wave is nearly finished, use the remaining combat time to prepare your next cave entry. A drone, turret, or other automated defense can let you begin mining earlier, but only do this when the spider is safe. Losing health to force a few extra seconds is usually a poor trade, especially before you have reliable repairs.
- Before entering: check the timer, vacuum capacity, health, and the next upgrade you are farming.
- Inside the cave: move toward the rear, mining high-priority deposits first.
- On the return: vacuum the route in one pass and collect any loose resources near the exit.
- At the spider: deposit immediately, buy the upgrade that improves mining speed, capacity, movement, or survivability, then repeat.
- Between caves: search for anomalies only when the route does not put you behind the next wave.
| Situation | Best decision |
|---|---|
| Vacuum nearly full | Keep mining until the return route is short, then collect from the far side back. |
| One weak enemy remains | Use caution; delaying a wave can help, but never trade substantial health for mining time. |
| A cave contains only common materials | Take the safest useful deposits, then move toward the biome that matches your upgrade plan. |
| A rare material is visible | Prioritize it even if the route is less tidy, provided you can return before the wave becomes dangerous. |
Because cave layouts and anomaly placements vary, a repeatable timing-and-routing habit is more dependable than claiming one universally best cave.
Deep Threat
How to farm gold and the DLC materials
Deep Threat adds new biomes, weapons, equipment, abilities, relics, and blueprints. It also introduces a separate resource progression. Community documentation and the expansion’s Steam page indicate that these materials are scarce and tied to particular DLC biomes, so the correct approach is to farm them before crossing the relevant transition.
Gold is an early DLC priority when it is required by your planned weapon or module. Do not spend it casually on an upgrade that does not improve your current run. Once you leave a biome, the same resource may no longer be available, making early routing more important than in the base game. Later DLC materials follow the same principle: identify the biome, clear the available deposits, and only then advance.
- Enter the DLC with a strong base-game permanent-upgrade foundation rather than relying on common materials alone.
- Reserve early gold for the mining tool, weapon, or module that lets you reach later biomes safely.
- Clear every practical gold deposit in the opening biome before moving through the cloud or zone boundary.
- Treat later DLC materials as separate currencies for DLC upgrades; do not assume base-game resources can substitute for them.
- If a run cannot reach the required biome or mining power, restart efficiency may be better than spending a long run on low-value deposits.
| DLC farming priority | Recommendation |
|---|---|
| Early gold | Secure it before leaving the first relevant biome. |
| Middle-tier material | Use the improved mining setup to clear its entire biome rather than taking isolated deposits. |
| Late-tier material | Farm it only after the run has enough damage and survivability to make the transition worthwhile. |
| DLC blueprint or relic | Search special rooms after protecting the run’s required material budget. |
Community references use inconsistent translations for some Deep Threat materials. Gold is consistently identifiable, but the exact English names of every later resource should be checked against the in-game label on your platform.
FAQ
Common questions
How do you get coins in Wall World?
You do not farm a conventional coin balance. Mine deposits during runs, return them to the Robospider, and use the resulting progression and materials for permanent, weapon, equipment, exosuit, and repair upgrades.
How do you get diamonds in Wall World?
Search the rocky starting-region caves and other caves that use the rocky or diamond resource family. Diamonds are a material for upgrades, not a universal shop currency, and exact cave contents can vary.
What is the best gold farm?
For the Deep Threat expansion, the best practical gold farm is to clear the opening biome thoroughly before crossing its transition. Gold is biome-specific, so leaving early can prevent further gold deposits from appearing in that run.
Are gems and crystals different currencies?
They are generally different materials with different biome sources and upgrade uses. Amethyst, ceramic crystals, red quartz, and other named resources should be treated as separate upgrade ingredients unless the in-game upgrade screen says otherwise.
Should I farm common resources or rush a higher biome?
Farm common resources when you need mining, movement, capacity, or survivability upgrades. Rush a higher biome when a specific weapon or module is blocked by its material. The right choice depends on your next upgrade, not on a universal resource ranking.
