EA and DICE have finally given a name to the battle royale component of Battlefield V. Called "Firestorm", the game mode is shown in a new trailer called "This is Battlefield V". You can see the map in the trailer below at about the one-minute mark.
Firestorm seems an appropriate name too: The edge of the map is a fiery circle that slow constricts, forcing players into closer and closer proximity to one another. After all, the ultimate goal is to be the last soldier standing.
