As a long time fan of STALKER games (including Anomaly), this game just plain sucks. Even after a multitude of patches so far, it's buggy and poorly optimized. Unreal engine was a poor choice by the devs, it's awful to begin with. Even overlooking all that - the game just lacks the soul and that immersive feeling previous STALKER games had. On top of that just a slew of other bad and lazy design decisions and lack of big and small QOL things all over the place. Don't even get me started on the main quest line and the driving motivations of your main character factored in. And lastly, the so very annoying cut scenes with complete take-away of your character agency and just doing out-of-character stuff. Ughh. I honestly can't believe I'd ever say this, having been so eagerly waiting for this game, but it's a total disappointment and a pass for me.
Whatever redeeming qualities the story and dialogs offer in this game gets completely wiped out by the most clunkiest and infuriatingly terrible combat (both ranged or melee) mechanics. And no unofficial patch can help with that. Bleh. I can't believe for my sanity that I managed somehow to finish this game back at it's original release...
Patch 2.0+ and this DLC have made the game even more buggy, unstable and hardly playable. v1.6.3 used to run stable and reliable for me, never an issue. Now, constant crashes and hard freezes. That's not even to mention the very questionable skill tree redesign and other harebrained changes that were not warranted. Awful.
