I still haven't beaten I choose the Impossible on Bioshock, however, I wanted to remark that I am approaching battles in a fundamentally different way than I did when I played it on PC twice before. I find myself relying on the environment more than ever, and that telekenisis is my best friend when it comes to Big Daddies and Nitros.
Speaking of Big Daddies, those M'fers are hard as balls on Survivor unless you use every aspect of the environment to your advantage. Every fight I've had with them on this mode has been memorable and extremely satisfying especially when you use very little amno to kill them.
Spoiler:
I just killed the first big daddy in Arcadia by luring it into a room with electrical traps (Which I ducked under to get around leaving them for the BD to hit) and hacked gun turrents (veterans will know which room I'm talking about). It died in less than a minute and all I used was a handfull of bullets from my machine gun to get it to follow me.
