It's not that the game was hard, it's just that the Big Daddy's are difficult to kill on this difficulty setting. One method that I developed for killing the Big Daddy's was to shoot a couple of proximity mines around the big daddy, then hit them directly with a regular mine or heat-seeking mine. It takes away about half of their health or more depending on how close you get the mines and also how many you laid out.
Also, sometimes I'd create a path of proximity mines that they'll run into whenever they try to slide/rush up to hit you. Explosive shotgun rounds are also very affective on the hard difficulty setting. Those are some things that I did to help me make it through the game and get the Brass Balls achievement, so if you're feeling stuck or having difficulty beating the Big Daddy's for that achievement, you may want to try that method and see how it works out for you.
