Fully Upgraded a Plasmid10
Fully upgrade one of your Plasmids to the level 3 version at a Gatherer's Garden.
Each Plasmid has three levels which can be bought form a Gatherer's Garden or found. You can't backtrack so make sure that you collect as many Plasmids as possible. Buy any of these level three upgrades and the achievement will unlock.
