LOS ANGELES (AP) — Rapper 2 Milly filed a lawsuit Wednesday against the makers of “Fortnite,” saying they are illegally using a dance he created in their wildly popular video game.

The Brooklyn-based rapper, whose real name is Terrence Ferguson, alleges that North Carolina-based “Fortnite”-maker Epic Games misappropriated his moves without compensation or credit in the lawsuit filed in federal court in Los Angeles.

The lawsuit states that the dance known on “Fortnite” as “Swipe It,” one of many that players can buy for their characters, is taken from the “Milly Rock,” a dance he came up with in 2011 that caught on as a craze in the summer of 2015 after the release of a song and video of the same name.

Ferguson says the game both steals his creation and appropriates his likeness. He’s asking for a judge’s order that the game stop using the dance, and for damages.

“They never even asked my permission,” 2 Milly said.

Epic Games spokesman Nick Chester declined comment.
