EVE

EVE is a modified version of ADAM which allows 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 bar meter with blue liquid; it decreases when the player uses a Plasmid, and refills when the player uses 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.

Behind the Scenes

 * EVE and ADAM are a reference to the Biblical characters Adam and Eve, 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 the Plasmids were the main cause of the fall by causing insanity. It is also a modified version of ADAM, as Eve was known to have been made from a rib of Adam.


 * The original EVE Hypo (as seen in the BioShock X06 trailer ), was 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.
 * The pikmin series was originally going to be a game named Adam and Eve, which is less interactive, and later changed to Pikmin and Pikmin 2, and the upcoming game Pikmin 3.
