Splicers are genetically modified beings found in the video game series BioShock. They are former humans who have undergone extreme alterations due to the use of a substance called ADAM, which grants them superhuman abilities but also leads to severe physical and mental deterioration. Splicers are often depicted as hostile and erratic, making them a significant threat to players in the game. In the BioShock universe, Splicers are a product of the underwater city of Rapture, where the pursuit of genetic enhancement spiraled out of control. Their appearance varies widely, reflecting the different ways they have abused ADAM. This transformation serves as a cautionary tale about the dangers of unchecked scientific experimentation and the consequences of addiction.
