Publisher Dreamhaven and Sunderfolk developer Secret Door have announced Shadowstone, a turn-based cooperative tactics roguelite game for up to four players. It will launch in Early Access for PC via Steam and Epic Games Store in 2026 for $14.99.
“Shadowstone is a natural next step for our team after Sunderfolk,” said Secret Door studio head Chris Sigaty in a press release. “Inspired by some of our favorite roguelikes, the world and characters of the Sunderlands are back, but in a more dangerous, more challenging, and even more engaging strategic experience.”
Dreamhaven CE and co-founder Mike Morhaime added, “The team at Secret Door continues to innovate with games that bring people together in positive ways. Shadowstone reflects that commitment by expanding the beloved Sunderfolk universe, and in a way that allows players to group up or take on this challenging adventure solo.”
Here is an overview of the game, via its Steam page:
About
Shadowstone is a one-to-four-player tactics game where players must master strategic positioning and powerful hero synergies to survive against the unrelenting horrors of the Sunderlands.
Key Features
- Master Tactical Gameplay – Deliberate positioning and manipulation of elements in each encounter is core to the turn-based tactical gameplay of Shadowstone. Survival hinges on utilizing your hero’s unique skills such as using the Witch’s ability to duplicate healing and exploding mushrooms or the Berserker’s charge to displace enemies into dangerous lava.
- Endless Combinations – Each attempt to escape the shadowstone infested ruins presents a new nightmare with an endless array of randomized rooms and monsters. Players must adapt their strategy every run, relying on a constantly evolving pool of skill cards, versatile equipment, and adaptive powerups.
- Powerful Hero Synergies – Build overpowered synergies by upgrading and selecting complementary spells across your heroes. Execute complex multi-hero ability combinations to devastate enemy monsters, even when playing solo.
- Up to Four-Player Cooperative Play – Take command of multiple heroes solo, or band together with up to four players in online multiplayer. Mastering the strengths and weaknesses of different party compositions with highly cooperative strategy is essential to survive against the horrors shrouded in shadowstone power.
