Epic battles, lots of blood and good graphics, what can you ask of more ?
When you start, the combat is pretty basic, but as you buy more techniques it becomes better and better, I, for one, don't find it boring and is, on the other hand, very exciting.
There isn't much of a developped storyline but the addictive combat makes it up for it and the time going around the island to find bags, urns and treasure chests for more gold is, not like one would think, far from being long and boring, as maps are available to buy showing yellow dots on the radar where they are.
The missions are repetitive but the amount of combat, with just a bit of stealth (only if you want to take them out one by one instead of fighting the lot of them at the same time) makes it for the better.
Not like games similar to let's say, Dinasty Warriors, you can't take on an unbelievable amount of enemy on your own. Unless you have the army of viking backing you, trying to intercept one of the Legion patrols of 50+ men is suicidal (and it doesn't even have framerate issues when you see this huge amount of enemies walk by), and this adds to the feeling you're not a god, even if you were blessed by one.
So if you like brutal games where you fight great battles with a dragon and an army of bloodthirsty warriors backing you ... Viking: Battle for Asgard is the game for you.
