It can't be stressed enough for people potentially interested in this game that it's not a straight forward FPS.
I had initially tried the demo and approached it more like that and thought the combat was shit essentially. Something told me to give it another chance and I'm extremely glad I did. It's one of my favorite games since Bloodborne hands down, if not my favorite.
The reason I mentioned it not being an FPS basically is that you have to really use your wits and think outside the box, at least at the higher difficulty level I chose, and it's glorious when your plants come together. You can't really run and gun and the encounters should be approached more like puzzles with scanning revealing enemies' weaknesses to take advantage of.
I've set up some pretty elaborate and on-the-fly series of traps for phantoms when I barely had any ammo and it worked beautifully. Those moments in a game when shit actually works logically and you sit there thinking "oh wow...damn".
I had a very memorable encounter where I knew a higher level (forget which one) Phantom was a floor below me and I could see him moving about through the grating. I grabbed a turret from another room and set that up where I knew he would have to turn left if coming up the stair case. Next I picked up an explosive barrel and positioned it at the stair landing slightly below the turret ran downstairs and popped a pistol bullet into its back to aggro it. Jetted back up the stairs and shot one of the wall pipes for toxic damage, while he was being stunned by that hurled the barrel, ran further up the stairs and watched the turret finish it off as soon as it turned the corner upstairs.
This type of thing may not be everyone's cup of tea coming in with the false impression it's a regular FPS based on the trailers etc., but I have to say that the realization that shit like this works, and the subsequent constant implementation of it in other scenarios, had me cheering at the screen.
And yeah, Talos I is one of the coolest, most logical and well design video game location I've seen in a long time.
My biggest complaint are the loading times between areas. They truly are horrible and can get on my nerves to the point of considering if I should stop for the night before facing another one of those.
PS: I've also gone human-only so far. Will go crazy with powers on my second playthrough.
