Crystal Mine

Each Crystal Mine expedition takes you through three zones: the Crystal Vein, Deep Cavern and Planet Core. Tap the crystal, buy equipment and complete sequential goals while your automatic income grows. After the first expedition, you can choose a contract with temporary conditions. The base shard reward is guaranteed, and completing the contract adds one more shard. Core Resonance may interrupt the routine: catch helpful pulses, avoid hazards, then take a safe reward or risk the charge for a larger one. A mistake never removes resources you already earned. Permanent shards speed up future expeditions and help you improve your best time. The mine also keeps producing while you are away.
