Mithril

Mithril is a procedurally generated voxel mining survival game set in caves where excavation has physical consequences. Removing rock shifts structural stress through the surrounding stone, so tunnels may need struts to prevent collapses. Each descent takes place in a different cave system with layered rock and varied geological formations. The game also lets you trigger Dormancy, simulating deep geological time in the cave. Water can carry minerals and concentrate ores, while lava and heat can transform rock into new minerals. Build pipelines with crushers, furnaces, conveyors and storage to extract and process resources as you explore.

The source describes creatures that learn from player actions, online and local co-op for up to four, and a Freeplay mode without creatures as features planned for launch, but explicitly says these are not featured in the demo.

Gameplay and features

• Cave stability: Mining changes how weight is distributed, and structural stress propagates through rock in real time. Support tunnels with struts or risk a collapse.
• Dormancy and geology: Trigger Dormancy to simulate deep geological change. Water can concentrate minerals along its path, while lava-driven heat can create new minerals.
• Mining and processing chains: Set up pipelines using crushers, furnaces, conveyors and storage to extract, process and deliver resources while you continue exploring.
• Changing cave systems: Explore procedurally generated caves with layered rock strata, mineral veins, stalactites, flowstone, crystal growths, lava pools and water systems.

Frequently asked questions

What happens when you mine too much rock?

Removing rock shifts structural stress through the cave. If tunnels are left without adequate support, the surrounding stone can collapse.

What does Dormancy do?

Dormancy simulates deep geological time in the cave. Water movement can concentrate ores, and heat from lava can transform rock into new minerals.

Does the demo include creatures or co-op?

The supplied description says creatures, online and local co-op for up to four, and Freeplay without creatures are not featured in the demo and are planned for launch.
