During EA's E3 2018 press conference, Battlefield V developer DICE confirmed that a battle royale mode will be available in the game at some point. We caught up with DICE creative director Lars Gustavsson at the EA Play event in Hollywood and asked him where the idea came from.

He told us that games like Fortnite and PUBG are popular among DICE employees (as well as pretty much everyone else on the planet). The idea to add a battle royale mode to Battlefield V came from conversations DICE developers were having about the game inside the studio as opposed to being a directive that EA handed down to the studio, he suggested.
