Back 4 Blood teases second expansion with Act 5 and a creepy twist

Turtle Rock Studios has teased the next big expansion for the co-op zombie shooter Back 4 Blood, and its looking like the Ridden won’t be the only threat players have to face.

“We’d love to confirm the release date for our Expansion 2, but we need a bit more time. It’s an exciting update and we’re so pumped, it’s been like a cult around these parts – some of us are so giddy that we Act like we’re 5,” Turtle Rock wrote on Twitter.

Coupled with the teaser image, there are two obvious clues as to what we can expect. First, the upcoming expansion will provide Back 4 Blood with the proper new chapter—Act 5—that fans have asked for. (The first big expansion, Tunnels of Terror, added roguelike-ish Ridden Hives to the existing acts.) Second, the Cleaners will encounter some sort of cult of human survivors.

Judging by the image, this isn’t just one of those NXIVM deals where someone is scamming and exploiting followers for money (and worse). This is a violent, probably Ridden-worshipping group that likes to string up corpses and build creepy towers.

Still, as the statement makes clear, we’ll have to wait a bit longer to experience this mystery expansion for ourselves. Given the timing of the announcement, it’s unlikely we’ll hear anything more about the release during this week’s San Diego Comic-Con, so August may be the soonest we get more news.

Back 4 Blood is out now on PlayStation 5, Xbox Series X/S, PlayStation 4, Xbox One, and Windows PC.
