You play as Ragnar, just recently reached the status of Odinsblade in your village that protects one of Odin's Runestones. The game starts with very crude "tutorial" obviously meant for people already familiar with games (of this type), only telling you details on things that were different from other games of the time.
After talking and running around a bit, you get into a mockup fight with the "strongest" of the village. Who, although can take a beating, uses ridiculously simple combat tactics that are easily beaten. After beating him up, the village gets attacked by some stupidhead viking thinking serving Loki is actually good idea and sens Ragnar and his fellow vikings to the bottom of the sea, killing everyone, you included.
While slowly descending towards the bottom of the sea, quite dead as you are, you hear the voice of Odin, who demands you to awaken, explaining its not your time yet. And so you are miraculously (although not very dramatically) resurrected, at full health and ready to beat some ass. But where are you? In some natural caves filled with bloodthirsty critters, and you're supposed to beat through them before you can go about stomping the renegade Loki worshipping vikings who so deserve a grand beating by your Odin-granted powers of vengeance. Meaning, the game instantly devolves to simple hack-and-slash adventure for a loooooong time from the start with some rare bits of plot thrown in for measure so common of the games at that time.
On non-spoiler frontier, you almost always have 3 weapons (sword, mace and axe) and a shield. Each weapon offers one magical power you can use after charging up your magical batteries by beating up people, and these change with newer weapons. You can even throw them at your enemies if you feel so inclined and this is actually good idea when a lot of weapons of that type are lying around or you just want to get rid of your old crappier one. Shields can be broken, both your's and your enemies' (it was either axe or mace that excelled in this, I forgot), but despite this small potential setback, shields are important part of survival.

The game was quite fun back in the days, but like with many 3D games, it's hard to appreciate it after the technology behind it has gone so far from those primitive times.
