I can tell that the game excels in that area, they do a really good job I think.
And the hardest difficulty on any game is bonkers, let alone a Shooter. Have you thought about dialing the difficulty down for yourself if you're struggling?
Bioshock Infinite has really good imagery, the backgrounds are so nice to look at. I got a bit bored with the game but I’m about two chapters away from the end so I’ll push through. I’m on the hardest difficulty though so the inevitable endless waves of enemies that constantly attack you throughout the final stages are really frustrating lol, it’s like five hits and ur dead.
