About this game
One night, someone left a demon baby on Finn the Viking’s doorstep.
He named her Lumi and raised her as his own daughter.
Now Mr. Shadow has taken her back to the underworld.
Embark on a rescue across seven distinct worlds as Finn. Harness the powers of Viking helmets and uncover the ruins of an ancient civilization that thrived millions of years before Vikings or demons ever walked the earth.
Explore Seven Unique Worlds
Begin in a cozy Viking village, then venture into strange and dangerous realms: an enormous animal graveyard, monster-infested caves, frozen mountain peaks, abandoned mines, forgotten kingdoms, and finally Mr. Shadow’s dark domain at the edge of the underworld.
Each world has its own striking visual identity, platforming challenges, enemies, hazards, secrets, and mysterious ancient structures.
Master the Viking Helmets
Discover and equip Viking helmets, each granting a unique power.
Swap between them to defeat enemies, manipulate the environment, overcome obstacles, reach hidden areas, and open new paths. The right helmet at the right moment can turn an impossible obstacle into a satisfying victory.
Uncover the Mystery of the Ancients
Beneath the mountains, ruined machines still hum with forgotten power.
Massive skeletons of long-extinct giants lie buried in the earth.
Temples and monuments remain as silent witnesses to a civilization that should never have existed.
Bringing Lumi home is only the beginning. The deeper Finn travels, the more he uncovers about the true history of the world.
