I'm not a big fan of the rogue lite/like genre, but I have to admit that this surprisingly works pretty well! I enjoyed the experience and I think it takes the biggest strenght of the core game (the combat system) and brings it in a very different context, but it still doesn't feel forced at all.
The thing I was most interested in though was the story, and even if it didn't deliver the ending to Ragnarok i would have hoped for, it still brought a satisfying sense of conclusion to Kratos' story and struggles. I appreciated it a lot, but I think this will hit much harder for those who have played the og games.
Most impressive thing is they decided to give this DLC for free; it feels criminal to play this without paying for it
