Stoneheart Archive is a moving-base survival roguelike about protecting the last library in a forgotten world. The castle moves on its own, and you need to keep it alive. Build defensive towers to protect it from enemies. Venture out to find ruins, collect resources, recover lost knowledge, and race back to safety. Use knowledge to unlock new towers, restore settlements, and shape the future of the world. Each run creates a different version of the archive, from a fortress of bells and flame to a plague-medicine sanctuary or a lightning-powered war library, so you can experiment with wildly different builds each run.
