The Energy Hall proper can be accessed once at least one of the 3 Energy Halls has been fully repaired. The repairs themselves can be started once the corresponding Eden Maze has been completed.
Once fully repaired, each energy hall produces some ressources:
- Broken Energy Hall No. 1: Gas (at the extreme right of Eden)
- Broken Energy Hall No. 2: Uranium Ore (left-most hall, besides Tarmac)
- Broken Energy Hall No. 3: Electricity (just left of Hall No. 1)
Research can be done at the Tech Hall to improve the max storage capacity, as well as increase the gains per minute.
The interface is very simple, it shows the current production levels for the 3 resources and the maximum amount that can be stocked. It also provides a shortcut button to the related researches at the Tech Hall.
