Valhalla Hills Sands of the Damned! In the first DLC of the Viking adventure Valhala Hills, our valiant heroes brave the harshness of desert survival. Scorpions and mummies are not the only challanges on the road to Valhalla, though. The earth itself will make life difficult, as it lies barren and dry without irrigation. Face the challenge, leave no oasis unexplored and fight for your place in Valhalla.
