Review - MÖRK BORG - Swedish fantasy metal, but what kind of metal?

We've been seeing scads of good RPGs coming out of Sweden in the last couple years, or so I am told. I'll be honest: my familiarity with Swedish role-playing consists of two vectors: Kult and games by Free League (or Fria Ligan if you prefer). Is that representative? Kult is great and Free League does great stuff, so I can't exactly argue with the rumors.

You know this is the shit, right?

Anyway, Free League's latest offering in this vein is this literal bad boy:

Whaaaaaaat?

So what's going on with this? Is this all style, or is there substance? And clearly this is METAL, but I ask you: what kind of metal is it? The marketing suggests its "Doom Metal," but I have my doubts.
