Press release:
Los Angeles, CA – July 30, 2026 – Solo developer ThornSpire Games has launched their medieval sci-fi strategy game Stoneguard today on Steam Early Access for $6.99 with 15% discount available through August 6th. Take a look at Stoneguard in the newly released launch trailer.

Stoneguard combines the open-ended sandbox gameplay of a survival sim with the tactics of a strategy game where players must defend their precious Lifestone either solo or in teams with up to four player co-op from an onslaught of invaders. Build and manage a fortified settlement by day, then defend it by night against relentless waves of monstrous enemies. Craft walls, towers, and defenses, recruit survivors, and manage resources to keep your community alive in a world on the brink of collapse. Players can experience Stoneguard solo or team up in co-op with up to four players, coordinating strategies and sharing resources to protect the Lifestone together.

Rather than offering a god’s eye view of the landscape, players take on the role of the current Ruler of Earth, who has escaped the capital with the Lifestone to protect it from alien invaders. Combat is brutal and tactical where precise weapon strikes can sever limbs, permanently affecting enemies and comrades alike. Forge powerful weapons from the amputated limbs of your fallen foes. Every lost limb carries severe consequences, hindering your performance in both battle and daily survival. But as long as the Lifestone is protected, there are ways to heal your battle wounds.

Command your forces through escalating nighttime assaults, face powerful bosses, and craft weapons forged from fallen monsters. Experience a unique blend of base-building, resource management, and real-time combat from a third-person perspective, shaped by a dynamic day–night cycle.

Stoneguard will remain in active development, with player feedback critical in influencing its road to completion.

“We love strategy defense games and immersive sandbox survival games,” said husband and wife duo William and Honor Hasketton from ThornSpire Games.

“Stoneguard combines both into something fresh and tactical. As the Ruler of Earth, you’ll manage your settlement and your recruited survivors to keep the precious Lifestone from being stolen each night. Since it’s coming to Early Access, your feedback will be instrumental in helping us improve Stoneguard as we aim for 1.0.”
