A gameplay trailer for Battlefield 2042 was shown today during E3's Xbox & Bethesda Games Showcase. Check out the gameplay trailer below. Most of the trailer shows vehicle gameplay and not much infantry gameplay. At the end of the trailer it says to prepare for more on July 22, 2021, so we'll have to wait until then for more trailers. I'm hoping they show and post more information before then though.
