Mining, Power and Research in Wall World Strategy
The economy starts with basic extraction and grows into a more complex chain. Mines sit inside the Wall, where miners work excavation points; electricity is its own system; and the research tree improves gathering, cuts costs, strengthens defense, automates work and opens new areas. Mining and electricity were both completely overhauled after the playtest, and the full game expands the research tree with new structures.
9 Listed mining, power and research changes
4 Mining changes
4 Electricity changes
Expanded Research tree in 1.0
Keep the chain running Keep miners working and resources flowing into storage, keep the power balance positive, and pick research that removes your current bottleneck, whether that is gathering, cost, defense or automation.
Sheet 01
Mines and miners
- Mines are inside the Wall — Mining takes place in mines dug into the Wall itself. The Demo Update fixed a rare camera glitch when leaving the first mine and repaired sounds inside them.
- Miners collect automatically — Since the Demo Update, miners pick up mined resources on their own when they are available, so you no longer need to chase loose output.
- Empty points — Miners used to fly around excavation points that had run dry; the demo fixed that, which makes an exhausted point easier to spot.
- Extra storage — Additional storage buildings hold surplus resources. A demo fix makes sure their amounts save and load correctly.

Sheet 02
Electricity
- A separate system — Electricity works as its own system next to resources. It received a complete overhaul between the playtest and the demo.
- Rebalanced in the demo — The Demo Update improved the electricity system again and refined the power balance, so numbers from the playtest no longer apply.
- Domes draw on it — Bugs when switching off the small energy dome were filed under power fixes, a reminder that defensive structures are part of your power plan.
- Expand power with the colony — Every new production and defense building adds to the load. Grow generation together with the colony instead of after shortages appear.

The research tree
- What it improves — Technologies improve resource gathering and processing, reduce costs and raise efficiency across the colony.
- Defense and automation — Some technologies strengthen defense against external threats, others automate key processes or speed up infrastructure building.
- Opening new areas — Research can also expand your ability to explore new areas of the Wall, which ties it to robo-spider expeditions.
- Bigger in 1.0 — The release reveal confirms an expanded research tree with new structures; individual technologies and their costs have not been listed yet.
Linked changes
- Added — Expanded research tree with new structures — Release 1.0
- Improved — Resource, weather, wave, task and research panels — Playtest v0.3.0

Where the economy leads
Resources, power and research feed the rest of the colony. These are the three biggest consumers.
