The reason this is such a big deal is that many titles in previous console generations locked players out if they did not own any DLC. For example, Call of Duty: Modern Warfare 2 would boot you out of matchmaking if you were with anyone who had purchased DLC maps.
That’s not the case with Back 4 Blood though, as explained in a post on the game’s official website.
IN PVE, IF YOUR PARTY LEADER OWNS A PAID CONTENT DROP, YOU WILL BE ABLE TO PLAY THAT CONTENT WITH THEM — INCLUDING MAPS, GAMEPLAY AND CAMPAIGN.
No separation. No exclusion.No split.
Turtle Rock Studios offered an in-depth look at Back 4 Blood’s PvP offering, Swarm Mode, during a dedicated livestream on Sunday night. Read up on it here.
Back 4 Blood is scheduled for release on PS5, PS4, PC, Xbox Series X/S and Xbox One on October 12, 2021.
