Well i'll just post impressions for what it is for me.
First of all the very core is off, the black bars with the camera placement makes everything strange as almost 30% of my screen is for my character. simple stuff like looking around, enjoy the environments and taking cover isn't fluid. It's not broken but i feel it didn't hit the sweet spot either. The UI is good except the weapon selection, which takes almost 30% of the screen while up, while your left side of the screen is your character and your vertical screen sides are black. There's so much room left to engage.
The controls aren't perfect in a genre that has been perfected.
Cover based games like Gears or Uncharted or The last of us did really good job there.
I don't see why RAD just didn't copy the formula, there's no switching cover corners, getting out of cover is a different button then getting into cover, no option to change control layouts at all, no 180 quick turn option, friendly NPC get you out of cover or in you'r way etc...
Weird design decisions:
when you want to stealth kill using triangle you need to time it with a flashing circle around it other wise you just fail. problem with this is, the flashing circle with the flashing triangle is so quick it's easy to miss. I mean, why can't i just press triangle and be done with it like when i face the enemy face to face? shouldn't be easier to kill them from behind unnoticed?
QTE's are weird, you get an explanation when there up but until you can read it for the first time you fail it, and it changes from time to time so you need to readjust but not as in God of war that you knew a head the general idea how to tackle the QTE.
You get a lot of item inspecting to do, but when you get an audio log you need to manually listen to it from the pause menu.
Having one primary weapon is fine, but your sniper rifle fills that spot and as soon as someone comes behind you there's only your pistol and it doesn't cut it. instead of 2 grenade slots a third slot for heavy/sniper weapon could have been better.
Once you hold a lantern you cant take cover, why? Can't i just put the lantern down and dispatch my enemies in a not uncomfortable way? It's the DOOM 3 gun/flashlight dilemma again but with lantern/cover.
The mission structure is good though there's sometimes no continuity between them which strikes you pretty hard. So you can sometimes think "wait, i just were in that place, how i ended up here so fast? what happened in the meantime ? oh well..".
