A Control Drone is an information drone that is used by both Mercenaries and Spies to display video guides that inform the player what the current objectives are in the multiplayer mode Spies vs Mercs in Tom Clancy's Splinter Cell: Double Agent (Version 1).
Control Drones are stationary drones that remain at the starting/spawn locations of both the Spies and the Mercenaries. At the start of a play session, the Control Drone uses a projection function to shine instruction videos for the starting players to view before the game starts. The videos that the Control Drone displays varies depending on what type of game mode is currently being played. Control Drones are also essential to Spies, as Spies must return secure hacked data to the Conrol Drone in order to score.
