Located at various points in the game, a Gatherer's Garden is a vending machine that allows the player to purchase Plasmids, Gene Tonics, Plasmid Slots, Gene Tonic Slots, Health Upgrades, and EVE Upgrades. ADAM is used as currency for these purchases. When the player character is rewarded for rescuing Little Sisters, the Gatherer's Garden is the location where the gifts are left, stuffed inside a teddy bear. Unlike other machines found in Rapture, the Gatherer's Garden cannot be hacked.
