Oil rig

The oil rig produces fuel, one of the five basic resources. You can build a total of three oil rigs in your base, but the costs and requirements increase with each one you build, as follows:

The gallery below shows the oil rig at all different levels.

Like other resource buildings, an oil rig produces a certain amount of fuel per hour, which is stored in the building. The resources can be collected and moved to your warehouse (unless your warehouse is full of that resource) by clicking on the building. Once the building reaches its capacity, it will stop producing until the resources are collected in the warehouse.

Your journal has this to say about your oil rig: ''What luck, that the territory of the Osterberg fortress has extensive oil reserves. Constructed oil rigs will provide us with fuel - an extremely necessary resource in wartime. This "black gold" is so valued for a reason, thanks to it we will refuel walking machines and ensure the transfer of troops to the front line in time. In addition, our construction machines require fuel for work. Without the necessary refueling - the whole construction will stop. Construction of the second, and in the future - third oil rig should not be delayed. Our engineers also developed plans to improve and optimize production - upgrading the oil rigs will allow even costly operations. The Dominion shall shudder under the power of our war machines!''
