Make sure that there is enough Energy to start production.

Ensure that all required resources and components are available for production.

If you have all you need - in the inventory or/and in the Storage of the base - select the item you want to produce from the list of items available for production in a facility menu.
  

Click Produce. The item selected for production will be placed in the production queue. In this case, the resources used for production will be removed from the inventory. If there are not enough of them in the inventory, they will be taken from the Storage.

Up to 5 items of the same type can be produced in one production slot.

The number of items that are produced in one slot differs in different production facilities. You can see this amount under the production slot.

When the limit of the amount of production in one slot is reached, the next one can be activated.

If production has started, you will see the production timer.

Production can be accelerated by pressing the Speed ​​Up button. Acceleration consumes C-coins. If you do not have the required amount of c-coins at your disposal, you can buy them in the  In-game Store by clicking To Store button.

Produced items must be collected from the production facility.

The collected items will be placed to the inventory if you are at the base, or to the Base Storage.
