Resupply Drones deliver Resources between players. Only members of the same Alliance may send Resources to each other. In order to maximize the amount of Resources you can send, and the speed with which your Resupply Drones travel, you should research and upgrade the “Resupply Drone Capacity” and “Resupply Drone Speed” Techs, respectively.
You can also acquire extra Resupply Drone Capacity in exchange for Intel Files at the Store.
To be able to send more Resupply Drones at one time, research and upgrade the “Deployment Limit” Tech.
There are some limits that affect Resupply Drones:
- You can send a maximum of 5 Resupply Drones to the same player in one day
- You can send maximum of 20 Resupply Drones per day
- You may receive a maximum of 50,000 Resources per day from Resupply Drones
To send a Resupply Drone, find an Alliance Member on the Map or via the Alliance Center. Then, tap on the green icon depicting a truck, and select the type of Resource and the amount of Resources you wish to send. You will be notified when your Resources arrive at their destination, and again when your Resupply Drone returns to your Base.
