Just completed this after 45-ish hours. I played AW1 and Control and can say without a doubt this is a perfectly on point expansion of the Remedyverse. I think I spent 60% of the game with my mouth literally hanging open.
There are some minor plot holes (or as yet unexplained plot threads) , but overall it is gorgeous, enthralling and engaging both visually and auditorilly (if you're not playing with headphones, you are missing amazing sound design).
This is one of those games I wish I could play for the first time again.
