Dreamhaven, the company unveiled in 2020 by Blizzard co-founder Mike Morhaime, has something new(ish) in the works, a "tactics roguelike game" for 1-4 players called Shadowstone that's set to launch later this year.
Shadowstone is being developed by Secret Door, the team behind the 2025 tactics RPG Sunderfolk, and you may notice a certain similarity between the two games. For a good reason, and this is why I called it "new(ish)": Stonehaven is set in the same game world as Sunderfolk and will feature some heroes from that game, although Dreamhaven says it's "a standalone experience from Sunderfolk that requires no experience with its campaign."
