Drones are special types of items. Drones can provide additional firepower, healing, or shielding effects. Make a one-time purchase and then activate them whenever you need.

Drones can be upgraded to improve their stats, for a better appearance, and even to unlock unique skills.

After helping you, Drones need to be recharged (this happens automatically). You can't activate more than one Drone at a time, but are free to use a different Drone while one is recharging.
