BioShock 2 Plasmids

Unlike his later successors, Subject Delta is open to genetic alteration, allowing him the use of plasmids. He has a limited number of slots for actively equipped plasmids, and can swap them 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.

Subject Delta 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. Others will have to be bought at a Gatherer's Garden. The singleplayer campaign will feature plasmids from the first game, but they will present a significant difference from their earlier counterparts. Plasmids are upgradable, and unlock alternate or enhanced functions at each level.
