Getting the chaos blades was intense and mark out worthy the whole way. The sequence that got me the most was when Atreus was becoming arrogant. It was breaking my heart to see him behave that way.
Some other things i loved:
valk fights. Cool. Tough. Rewarding.
Baulder and Freyas arc was written very well. The writting of the entire game was brilliant.
The build of Thor was really great and the reveal was pretty rad. The cut to Mjölnir was HYPE.
The Laviathan Axe mechanics were bad ass too in general.
Great puzzles. Some of the optional chests were very tricky. The zelda based items progression fit very well.
Awesome game. I could easily keep going.
