This game is amazing. Plenty of reviews are out-of-date, so, you can still play , no need to download any random program. From what I see. You are forced to load up the game through the Ubisoft launcher, not sure on the implications of such, but the game runs really well. Only time I got a crash so far was when I fast traveled and got sent to my OS.

I'm still currently playing the game, trying to finish it on survival. So when I finish, I will update this with a better understanding of game play. Right now, This game is amazing.

Notes: Manhole in Palace bunker next to the Doctor can crash your game.
