Kinda disappointed with how broken stealth seems to be; not to mention how finicky hiding behind/under things can be at times.
The game's systems are just way too lenient with lines of sight and the like (leaning is especially ridiculous), making for some goofy-looking encounters largely devoid of tension.
Granted, I am playing on normal, but with the Neuromod that yields 200% damage for attacks on unaware enemies, plus some shotgun upgrades, I feel like I'm rocking a pretty, pretty, pretty OP build. The sense of dread that the game so strongly built in its opening stages is all but lost now.
I'm also disappointed with how willingly I've been reloading saves once firefights unintentionally break out. The game does just not feel nice as a shooter, mostly due to the crippling speed at which you move backwards, the sluggish aiming and the fact that enemy attacks can drop you in an instant.
Having said all that, I'm still really enjoying myself. The game's aesthetic and world design are enough to get it over the line in terms of fun and keeping you interested.
