An ancient force hides beneath the surface… and every night, it tries to break free.
In Crystal Siege, you must withstand relentless waves of enemies while protecting the crystal that holds everything together. But survival alone won’t be enough — you’ll need to use every moment of calm to expand, gather gold, and prepare for what’s coming.
Every decision matters. And every defeat… makes you stronger.
Venture beyond the safety of your base and uncover a world filled with danger, secrets, and opportunity.
Each run is unique, with unexpected events, and meaningful choices.
When darkness falls, the siege begins.
Face increasingly challenging waves of enemies, each with distinct behaviors and threats. Build defenses, position structures, and adapt your strategy to survive the night.
Learn from every attack. Improve. Endure longer.
Collect gold and crystals to invest it wisely to unlock powerful upgrades.
Strengthen your defenses, enhance your abilities, and shape your playstyle with each run. There’s no single path to victory — experiment and find what works best for you.
Defeat is not the end.
Each attempt brings you closer to mastery. Unlock permanent upgrades, new options, and powerful advantages that will change how you face the next cycle.
In Crystal Siege, progress is never lost… it evolves.
The crystal depends on you.
Will you endure long enough to uncover the truth behind the siege… or fall like those who came before?
