Electronic Arts have just dropped a new teaser trailer for the upcoming Battlefield V, although the trailer itself is pretty uneventful and short, it does confirm World War II as the new setting.
During a short sequence within the teaser itself, the HUD is displayed at the top of the screen, showing the British Union Jack and the German Iron Cross, confirming the setting.
