I just tried it for the first time since release, and I was pleasantly surprised. I'm not sure if I can recall another game changing that much after two updates.
It still seems subpar as an immersive sim, and it's not even in the same stratosphere as something like Prey or Dishonored, but it's come a long way from what it was at release.
They've improved the visuals in the environment quite a bit. I still don't like the art style, but at least there are no longer gaping holes in the scenery, and they've added stuff that improves the overall atmosphere.
A LOT of bugs have been squashed. The game was an utter joke in that aspect the last time I tried it, but I only noticed a couple of minor things this time.
The movement is still terrible though, and I don't get why they haven't addressed that. It feels like you're walking on the moon. You just sort of float through the air when you jump.
Overall I'm pretty impressed though. Not by the game but by the progress they've made in a relatively short amount of time. The game itself is still mediocre, but at least there might be some potential now.
