Unlike past games, EA's plans for Battlefield V post-launch support consist of free updates. Tides of War will see a series of major free expansions added to the game, the first of which--Chapter 1: Overture--is now available on PC, PS4, and Xbox One. Alongside a huge list of changes and adjustments, as detailed in the full patch notes, this introduces new content, primarily in the form of a new map and War Story, both of which you can see in the video above.
The map is called Panzerstorm, which is set in Belgium and focuses on tank battles. The War Story is called The Last Tiger and puts you in the role of a German soldier who pilots a tank. Aside from this, there's also the new Practice Range where you can experiment with weapons and vehicles as a training mode of sorts.
