Here's another technique to take out Big Daddies. He'll run into each dart and kill himself. Once that's done, shoot at the Big Daddy to get his attention and keep him running towards you. Take your 4-6 Trap Darts and line them down a hall or near where you can see a Big Daddy, making sure the path he'll take towards you is amply covered. All that's required is Electrical Trap Darts (4-6 per Big Daddy). Once you've obtained the Dart Gun, you can try this technique. When fighting a Big Daddy, use armor-piercing rounds, as they will deal considerable damage compared to regular rounds. If, however, you 'harvest' no more than one little sister but 'rescue' the others, you will get the good BioShock ending. If you choose to 'harvest' more than one little sister, you will get the bad BioShock ending. There are two possible endings for BioShock that depend on how you treated little sisters throughout the game. Now here's the fun part - simply find and attack another Big Daddy and your Big Daddy will attack it to protect you. All you have to do is use the Hypnotize Big Daddy Plasmid on a Big Daddy so that he thinks you're a Little Sister and protects you. In order to do this, you need the Hypnotize Big Daddy Plasmid and the Natural Camouflage Tonic. After a few hits, between 1-3 health packs should lie on the floor for you to grab, for free. While you can buy health packs at health stations for $10, you can get them for free by simply smashing the machines with your wrench.
