At the end of Battlefield V’s official Gamescom trailer, titled Devastation of Rotterdam, we get a glimpse of the upcoming battle royale mode.
Beginning at 1:38 of the video below, we are shown a snowy and mountainous region with a ring of fire in the center that is slowly shrinking.
The trailer then cuts to a tank breaking through a building, a soldier screaming “fall back!”, and ends with the same ring of fire quickly enclosing the tank, a soldier jumping off a tower, a flaming vehicle entering the fray and more.
This reveal was presented in a similar fashion to the Call of Duty: Black Ops 4 multiplayer trailer that also showed their battle royale mode at the end of the video.
