Tonic Slot

Tonic Slots allow the player to equip passive Gene Tonics. Tonic slot upgrades allow the player to carry one more tonic per slot purchased.
==BioShock==
The player begins the game with two slots in each of the three track types: the Combat Tonic Slot, Engineering Tonic Slot, and Physical Tonic Slot. Each track's slots can be extended separately by purchasing different slot upgrades from Gatherer's Garden machines found during the exploration of Rapture. Each of the slots cost 80 ADAM and the price doesn't change. Identically to the Plasmid Slot line, the maximum is six slots per track. The player can purchase a maximum of twelve tonic slots, an additional four per track. The Achievements/Trophies: "Bought One Slot", "Maxed One Track" and "Maxed All Tracks" are related to buying additional slots.

Tonic slots return as a purchasable upgrade. The player begins with four open tonic slots. The initial price for the first five purchases is 25 ADAM. It then increases to 35 ADAM for the next four successive purchases. The final five slots cost 45 ADAM each. A maximum of eighteen slots are available, and there is no longer any distinction between tonic types, thus the player may assign any tonic to any slot. The Achievement/Trophy: "Bought a Slot" is acquired by buying one slot in either the Tonic or Plasmid line.
