Warhammer: Vermintide 2's first DLC is called Shadows Over Bogenhafen and arrives August 28 on PC and Xbox One. There’s no real information other than that it will likely feature Grandfather Nurgle’s minions. There’s still no word on when the game will come to PS4 though.
There are too many Warhammer games, but one of the better ones of the last few years was the space-based RTS Battlefleet Gothic Armada. Which is now getting a sequel.
Total War: Warhammer had previously locked an entire race, the Chaos Warriors, behind pre-order DLC, but the developer has since reversed its position. Now, the Chaos Warriors will be free for anyone who pre-orders or buys the game—until a week after release. It’s a good compromise.
