Strategic resources are counted by levels. The more resources unit you control, the higher level you have in that resource, and character activities will not reduce resource level. Contrary to common believe, the absent ofdoes not prevent resource level from going beyond 3 or 4. The problem is, rather, in that four mines is needed for level 3 and eight mines for level 4, double or quadruple the requirement for level 2.
The only way to lost resources is by exchanging resources through diplomacy or actually losing resource supply.
When the game begins, there are five resources:
- Metal: Mined.
- Fuel: Mined and quite abundant.
- Chemical: Mined.
- Energy: Produced by power stations in the home base.
- Water: Supplied by the water pipe and as long as enemies are not controlling the pipe, you would do fine
After researching, two new resources will show up. Then their mines can be researched, and they are required for advanced productions.
