Fast answer
The answer before the background
Creeper World 4 resources form separate chains. Energy builds most normal units and supplies many weapons. Greenar is harvested by a Refinery and processed into Liftic; Redon is connected to power and processed into Arg; Bluite comes from eligible terrain or nodes and becomes Anti-Creeper. ERN crystals are not spendable money: assign one directly to an eligible unit or place it in the ERN Portal to improve a selected global category after the portal charges.
Ware chain
Name the source, processor and final use
| Source | Collection path | Output and examples |
|---|---|---|
| Tower coverage / Miner energy mode | Connected network | Energy for construction and many weapons. |
| Greenar crystal | Refinery to Factory | Liftic for Platforms, Rockets, Beacons and Sweepers. |
| Redon node | Connect node to power and use Factory | Arg for Missiles, Shields and Micro Rifts. |
| Bluite node or terrain | Connect or mine, then process | Anti-Creeper for Sprayers and AC Bombers. |
| ERN crystal | Excavate or collect, then assign | Direct unit enhancement or ERN Portal category. |
Factory
A Factory is useful only when a ware has an input
Building a Factory does not create Liftic, Arg or Anti-Creeper from nothing. It receives collected resources and converts them into usable wares. A Refinery belongs near accessible Greenar and needs the network; Redon and Bluite use different collection methods. Select the Factory panel to see stored material and current income before blaming a weapon for empty ammunition.
If a Missile has no Arg or a Sprayer has no Anti-Creeper, adding more of that weapon increases demand without solving supply. Secure the node, connect the processor and allow ware stock to recover. A Porter can move a chosen ware container to a remote front when the normal packet route is unsuitable.
ERN decisions
Assign the scarce upgrade to the current bottleneck
A direct ERN substantially improves an eligible unit, while the ERN Portal applies global categories after charging. The advanced reference notes that the portal takes time to reach full effect, so a short mission may benefit more from a direct early placement. A long map can justify global energy, weapon or movement improvements.
Crystals, eco and overload are ambiguous search terms. The standard game uses specific Greenar, Redon, Bluite, ware and ERN labels rather than a premium crystal wallet. Check the active map because a script can add its own economy. Do not confuse those legitimate scenario resources with websites promising coins, diamonds or gems.
FAQ
Common questions
How do I get Liftic?
Harvest Greenar with a Refinery and process it through the connected Factory.
How do I get Arg?
Connect a Redon node to power and let the Factory process the collected resource.
How do I collect an ERN?
Expose or reach the ERN crystal as the mission permits, then assign it directly or through the ERN Portal.
Is an ERN a currency?
No. It is a limited upgrade resource assigned to units or portal categories, not a premium coin wallet.
