The first Battlefield V teaser trailer was just shared via the Battlefield Twitter account. In this teaser trailer we see a soldier with an old style pilot glasses, presumably from the Second World War.
Furthermore, at the top we also see the British and Germanic Wehrmacht flags from that period, so we certainly know the setting through this trailer. The final announcement will follow on May 23 next, then we will learn more about Battlefield V.
Battlefield V Live Reveal on May 23 at 1 p.m. PT / 4 p.m. ET / 10 p.m. CEST.
