"In the Game Of Drones fights, two pilots try to bash each other’s drones out of the sky. That’s typically accomplished by maneuvering above one’s opponent and then crashing down on top of their propellers. The first drone to get knocked down three times loses.
If damaged, a drone’s pilot has 90 seconds to fix their vehicle, often by replacing a shattered propeller, and get it back up in the air to avoid a TKO. The battles resemble an aerial thumbwar, in that a missed attack leaves you low and vulnerable to a counter-strike.
Anyone who grew up watching BattleBots knows the thrill of technological competition. While the drone rodeo and Game Of Drones might seem niche now, I wouldn’t be surprised to see drone or robot sports get quite popular over the next five years. Seeing athletes risk their safety for our entertainment feels a lot less guilty when they’re machines."
