You have crashed.
You are stranded.
But you are not alone.
The Spiral Knights have awoken on an alien world. Their equipment stores have been raided and their starship, The Skylark, will not recover from the crash. Now they must work together to survive on a journey that will take them to the very core of the world.
Your Mission:
Take up your arms!
Cradle is a hostile planet teeming with all manner of alien creatures. Any hope of survival you may have rests on your ability to amass an arsenal of weapons and gear that will provide you with the right options for any environment. As a Spiral Knight you have total freedom to customize and use your arsenal however you choose!
Join your fellow knights in Haven
Once some kind of mining outpost, Haven serves as the makeshift base camp for Spiral HQ. From within the safety of its walls, knights can find an array of goods and services offered by the locals. Everything from purchasing new weapons and gear to alchemizing powerful items from strange materials is right at your fingertips!
Explore the mysteries of the Clockworks
Stretching deep below Haven, The Clockworks is a giant subterranean complex filled with pieces of strange worlds, dangerous creatures and fabulous treasure. Will you and your fellow knights answer its call to adventure?
Harness the power of the Arcade
Filled with strange machinery powered by Minerals claimed from the worlds below, Haven's Arcade is used by the Spiral Knights to build their own gates that cut unique paths into the underground Clockworks. (No two gates are alike!)
Take your adventure to the Core!
Spiral HQ is picking up a strong energy reading from deep within the planet's Core. Are you brave enough to face whatever dangers might lie between you and the secrets of this mysterious new world?
