BioShock 2 Gene Tonics

In the BioShock 2, the player as Subject Delta is able to choose from a vast selection of Gene Tonics to equip. With Tonic Slot upgrades, the player can equip up to eighteen tonics. Even though tonics have three classifications (combat, physical, and engineering), tonics can be mixed in any number from any classification up to the maximum. Tonics are found or purchased at Gatherer's Gardens.
