A battle-slain warrior, the Valkyries have ferried your soul to Valheim, the tenth Norse world. Besieged by creatures of chaos and ancient enemies of the gods, you are the newest custodian of the primordial purgatory, tasked with slaying Odin’s ancient rivals and bringing order to Valheim.

Your trials begin at the disarmingly peaceful centre of Valheim, but the gods reward the brave and glory awaits. Venture forth through imposing forests and snow-capped mountains, explore and harvest more valuable materials to craft deadlier weapons, sturdier armor, viking strongholds and outposts. Build a mighty longship and sail the great oceans in search of exotic lands … but be wary of sailing too far...
