EVE

EVE is the genetic substance which powers the use of Plasmids. In its liquid form, it glows bright blue and can be seen in the dark. The player's current EVE level is shown by a HUD bar meter with blue liquid; it decreases when the player uses a Plasmid, and refills when the player uses a means of replenishment. When EVE reaches zero, the use of Plasmids is unavailable to the player. The EVE meter has a hypodermic needle symbol on its left, as well as a number denoting the amount of EVE Hypos currently carried by the player.
EVE is the BioShock series equivalent of the "mana" found in many other games that powers magical attacks and spells, though what differentiates it is how it is actually a byproduct of ADAM.

==Behind the Scenes==
*EVE and ADAM are references to the eponymous Biblical characters who lived in paradise in the Garden of Eden until they fell from grace. The symbol for EVE is an apple, which is a reference to the forbidden fruit which Eve, then Adam, ate that caused them to be punished by God. This parallels the fall of Rapture and its citizens, as ADAM was the main cause of the fall by causing insanity and empowering belligerents.
**Additionally, ADAM being a key component in the production of EVE references how Eve was created from one of Adam's ribs.
*The original EVE Hypo (as seen in the BioShock X06 trailerBioShock X06 trailer at GameTrailers.com), had a smaller, leaner needle filled with a green murky liquid.
*As of February, 2010, the NECA (National Entertainment Collectibles Association) began marketing EVE hypo promotional replicas from the BioShock games.BioShock Eve Hypo Syringe at NECAOnline.com"BioShock 2 Replica Eve Hypo Syringe Unboxing" article on WouldYouKindly.com
