Billie Eilish is Ethermacdropping into Fortnite.

The Grammy and Oscar-winning recording artist has become a playable character for Fortnite Festival, a rhythm-based music game not unlike Rock Band. Eilish, 22, announced her imminent arrival to the virtual game's main stage in a post Monday on X that included a picture of her character in the game.

After teasing the partnership, Epic Games, the developer behind the massively popular online video game best known for its Battle Royale mode, released more details Tuesday.

What is the Fortnite Festival?

Epic Games worked with Rock Band developer Harmonix to add a musical mode called Fortnite Festival to the in-game experience in 2023.

Eilish is just the latest among a slate of stars, including Lady Gaga, Ariana Grande and The Weeknd, who have since graced the game's virtual main stage. Similar to Rock Band, the game mode allows players to join with up to three others to play a licensed soundtrack of hits songs and Fortnite originals on instruments of their choice.

If past events are any indication, players can likely expect to play as Eilish on the main stage performing her top hits that may include “Happier Than Ever,” “Therefore I Am” and “Oxytocin.”

As players progress through Season 3 of the Fortnite Festival, they can unlock rewards that include instruments, outfits and new songs to perform, according to Epic Games. Among those unlockable rewards is Eilish's neon green character skin and two Eilish-themed Instruments – a keytar and a microphone.

Season 3 ends June 13.
