To create the illusion of autonomous intelligence, the drones can be assigned three distinct attack maneuvers at runtime. Each maneuver is a repetitive series of predictable movements. Individually, the drone's behavior may look robotic, but when they are placed in a formation at specific positions on the race track, it could look like they are forming a strategy to outmaneuver the ...
