I have only ever played it on hard with vita-chambers off (because vita-chambers totally ruin it for me) and it was still stupidly easy, so yeah, that's basically the case. I'm not sure about console shooters in general, but the only real challenge in both Bioshocks has been at the beginning of the game. The more you upgrade your shit, the more you turn into a ridiculous beast.
