Plasmid Mastery Series — BioShock: The Collection eGuide

Title	Points	Trophy	Description
Maxed One Track	20	Bronze	Purchased every slot in one of the Plasmid or Tonic tracks. It’s up to you to decide when to earn this Achievement / Trophy based on how you handle the Little Sister encounters and to how diversified you’d like to make your plasmid and tonic collection. Taking a balanced approach to slot purchases will likely net you this Achievement / Trophy during the “Fort Frolic” chapter. You may want to purchase every available plasmid or physical tonic slot first.
Maxed All Tracks	50	Bronze	Purchased every slot in all four Plasmid and Tonic tracks. There are six slots in each of the four tracks, but you’ll only begin with two slots per track. Use the Gatherer’s Garden machines to purchase the extra slots one-by-one throughout your time in Rapture. There are opportunities to buy additional slots and unlock this Achievement / Trophy right up until the “Proving Grounds” chapter, but it is possible to earn it much sooner.
Bought One Slot	5	Bronze	Purchased one slot in any Plasmid or Tonic track. Plasmid Slots cost 100 Adam, but are worth every last drop. The first opportunity you’ll have to purchase a Plasmid Slot is at the Gatherer’s Garden in the Lower Wharf of the “Neptune’s Bounty” chapter. Don’t pass on the opportunity.
