Overview
Your starting oxygen tank lasts 40 seconds! Break through rock to find copper, gold and crystals. Choose whether to bank your loot or risk one more chest. Upgrade your pickaxe, backpack and air tank at camp. Each tank upgrade adds 5 seconds. Restore lift stations and explore deeper. Discover three layers of the mine, collect six relics and reach the treasure vault 100 meters underground. Every expedition generates a new map, and your progress is saved automatically.
