Very Very Very short. I'm glad i got this in a bundle/Sale. Only 5ish hours if you slack around, game can be beat in less than 2 hours if you're fast.

Peak. It continues to be insanely good.

TECHNICALLY, I have beat the main story of Valhalla, but there is much to go in terms of completing it. It's a great, short roguelike addon that gets us some juicy Kratos character growth and Mimir banter. Can't beat a price better than free.
