BioShock 2 Plasmids

Unlike his later successors, Subject Delta is open to genetic alteration, allowing him the use of Plasmids. He will be able to use plasmids and Weapons simultaneously. Up to eight plasmid slots are available, with three slots already available to the player from the start, and active plasmids can be swapped out at a Gene Bank. Upgrading a plasmid to the next level also unlocks an alternate method of use for that particular plasmid. Plasmids available will each have a unique upgrade tree, and most can be upgraded twice. While several plasmids can be found in the environment, most will have to be purchased from a Gatherer's Garden at a cost in ADAM.
