On this page of the RAGE 2 game guide we have provided information on how to find Spy Drones that hide in the game world. You will also learn how to effectively destroy the drone after it is detected.
Destroying 30 Spy Drones will grant you a golden trophy called Mata Hari Manners. In the game world there are more drones than the required 30 needed to get this achievement. You don't need to get to all the spy drones. You can stop the search after the destruction of the thirtieth.
Search for the spy drones every time you explore a new location. Drones emit a quiet sound and it can further help you find them. A sample Spy Drone is shown on the attached image. Expect that, for example, a drone may be attached to the wall of a building.
Complete Ground Control mission to track the drones with ease. Completing that mission unlocks access to Search & Recover projects. One of the level three skills is called Spy Drone Tracking. This project allows you to track their signals - they will appear on your compass.
Your compass doesn't necessarily have to point towards a drone. It can point you towards a container or a datapad. Still, try to follow it - unique loot is always welcomed.
The drone will start to run after you approach it, or you aim at it. Hurry up and destroy the drone before it flies away. To destroy drones, you can use a "standard" assault rifle or any other weapon that is characterized by high accuracy and a large range of fire. Fortunately, spy drones are weak and each one explodes after just a few hits.
As a reward for the destruction of each drone you get reputation points. The game also unlocks the associated drone log entry.
