The release of this game kind of snuck past me, so I didn't get it until Sunday. Got it for PS4.
I spent a few hours taking my time thoroughly searching the first map and taking out every enemy I could without breaking stealth and had a blast doing it!
I've been a fan of the series since the beginning, but this is easily the best of them. (Unless something goes horrendously awry in later levels.) There's now a co-op mode, which I wouldn't mind trying out. Survival mode from the last game made a return and seems a bit more solo friendly now. Every weapon in the game has mastery challenges to unlock. Each level also has challenges that you can attempt on subsequent playthroughs. Tagging enemies with binoculars now gives you their range and you can adjust your scope to compensate for the drop. Fully customizable loadouts with upgrade unlocks, rank unlocks for things like increasing the speed your heart rate drops, etc.
Mostly iterative and quality of life improvements from the last game, but all in all I find it very well done. If you're a fan of the series I highly recommend checking this one out. This will keep me busy for a long time unlocking everything and completing all the weapon mastery challenges.
Oh, and that bullet-cam X-ray cinematic never gets old.
