RAPTURE'S GENETIC EXPERIMENTS
Storyline of Big Daddy
Genetically programmed to search for the ADAM essential to the social fabric of their undersea city, Little Sisters roam through the portals and tunnels of Rapture. Because the substance they extract from the recently fallen is so precious, the girls are accompanied at all times by their fearsome, diving suit-clad protectors, the Big Daddies. Armed with a deadly drill, possessed of incredible strength, and capable of quick bursts of speed, the Big Daddies guard their charges jealously, making all who attempt to harm a Little Sister wish they hadn't.
