I've been playing on PC since release and overall have been quite happy with the game although there is definitely room for improvement. The story mode (which is also the tutorial) was quite well done and I enjoyed the story.
The AI leaves much to be desired, I have seen enemies take an elevator up to the top floor to walk past my heavy and then jump down to the ground floor. I also see enemies walking into the wall for 20 secs and then kneel and end their turn.
I haven't had the problems with crashing and losing progress that others are complaining about. The game has crashed twice in the 20+ hours of gameplay and both times I didn't lose any progress. I thought I was having a glitch when trying to pick up objectives but I figured out that I simply didn't have inventory space for my current weapon.
Overall this game has great potential and I'm looking forward to future updates.
