How do you get "BioShock" plasmids?

"BioShock" plasmids can be purchased throughout the game through the Gatherer's Garden by using ADAM. Other plasmids can be found throughout the game, such as the "Hypnotize Big Daddy" plasmid, which is received from a character named Brigid Tenenbaum as a reward for rescuing three Little Sisters.

The Gatherer's Garden is a series of vending machines that are found throughout the game for the players to purchase plasmids from. Those found early in the game will offer basic plasmids, such as the "Electro Bolt." Those found later in the game offer upgrades for early plasmids and more advanced plasmids, such as "Insect Swarm."
