Resource Bases are the main income of Resource Production in World War Online. Each Base produces a certain value of its respective Resource every minute depending on its level. There are 4 types of Resource Bases:

Resource Bases require a Worker to become active and each produces between 1 and 15 Resources per minute depending on its level.

There are also Resource Mines which are more expensive to build and upgrade, but they produce between 3 and 20 Resources per minute to compensate. They can only be built in their respective Mine District.

Additionally, while Resource Bases have the ability to train Units, they can only do so in rather small amounts.
