“The goal in [Fortnite: Battle Royale], as in most multiplayer shooter games,” writes Sarah Kaufman, “is to blow your enemies to shreds.” What does that have to do with dance? Well, players can buy preprogrammed moves for their avatars called “dance emotes,” which they use to dance on the dead bodies of the enemies they’ve blown to shreds. Dance emotes are so popular that the game pulls in $126 million every month, and players are starting to bust those moves themselves offline.
