When I first played the game, I refused to pause it, at least for 5 minutes. I barely stopped after playing for 5 hours. It took me 8 days to finish it! Very long game, as I usually finish games in 2-3 days. Maybe it's up to how you fast go and which difficulty you set it on. I played the game on Easy mode on my PS4 and I already got positive feelings for the game with some negative feelings.
Pros:
Graphics! Dude, those graphics are just amazing! Nothing ruined it.
Gameplay. Alright, no more comments.
Classic-and-old motion tracker. Nice! Especially, it WONT warn you that a movement just appeared on motion tracker like on A:CM.
Alien A.I. Unpredictable at most moments, deadly and one-hit killer! Wow? Wow.
The design of the area... Perfect... It gives me feelings of old years...
Human A.I. They are mainly for distraction and adds life to the game.
Voice acting, especially Synthetics.
Cons:
Story is bit long for a stupid thing.
Synthetics totally ignore the Alien which they shouldn't. Alien shouldn't ignore them at every time at all.
Alien can teleport if you arent looking at it and is already too far(Above 0.90 m).
No checkpoints on most crucial times, especially for newbies.
Difficulties dont really make a difference on A.I... Just resources.
I rate it 8/10. Perfect game.
