Stoneheart Archive is a moving-base survival roguelike about protecting the last library in a forgotten world.

Civilisation has fallen. Only the Archive remains: an ancient walking castle carrying the last surviving knowledge. You are its caretaker.

The Last Library Walks

The castle moves on its own, and you need to keep it alive. Set the course, clear the way, and climb aboard for a journey through the wilds. 

Collect. Expand. Protect.

Build defensive towers to protect it from enemies. Collect knowledge to level up, unlock new upgrade options, restore settlements, and change what your castle can become.

Survival Isn’t Guaranteed

The further you push from safety, the greater the reward - and the greater the risk. Venture out to find ruins, collect resources, recover lost knowledge, and race back to safety.

Knowledge Changes the World.

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.

Features

• Defend a giant walking castle as it travels across a ruined world.

• Leave safety behind to scavenge resources and recover lost knowledge.

• Repair and upgrade your castle between enemy attacks.

• Build defensive towers and unlock new tower upgrades each run.

• Visit settlements to exchange knowledge, repair damage, gather supplies, and unlock new towers.

• Create a different version of the archive each run through unique upgrade choices.
