Now repeat the hijacking process to pilot the drone wherever you need to go - with your operative riding on top. To climb on the drone, press X (on PlayStation) or A (on Xbox) next to it, as you would when scaling a low wall. Back out of controlling now with the Circle / B button to control your operative again. Now lower the drone to ground level, or whatever your operative is, so they are able to climb onto it. In short, once a Cargo Drone is within range, press L1 / LB as you would any hackable object, and select the hijack prompt. This mission occurs in the first 90 minutes or so of the game's critical path, and completing this mission is a good explainer of how riding drones work. The concept of riding on a drone is introduced early in the story as part of the Reporting for Duty mission, where you must recruit a construction worker with the ability to call in a Cargo Drone wherever they are.
