These gene tonics are designed to improve your abilities during combat. All tonic effects are passive, meaning that you'll enjoy their enhancements automatically just by having them assigned to a slot. If you want to make use of several of these nifty tonics at once, you're going to have to spend your hard-earned Adam on more slots at Rapture's various Gatherer's Garden vending machines. Should you choose to assign multiple versions of the same tonic, their effects are cumulative.
