Bioshock 2 is coming February 9th! Player can explore the ocean floor, recover from fights, marvel at the city from the outside and pick up special items. As seen by the demo, some of the special items include first aid kits, EVE Hypos, and special sea slugs. These sea slugs create ADAM, the genetic material for the production of Plasmids. Throughout the game the player will be forced to fight Rapture’s new Big Sisters, hybrids of sorts between the Big Daddy and older Little Sisters. A Big Sister attack will be spontaneous and unplanned, but if the player has a Little Sister with them at the time, she’ll give you a warning that a Big Sister is coming. Unlike the Big Daddies, they are extremely quick and arguably more powerful, able to extract ADAM from their enemies through a harvesting needle, straight into her bloodstream, which fuels “telekinetic abilities beyond anything previously thought possible.
