BioShock 2 1.0

BioShock 2 is the sequel to BioShock, and is designed to continue the grand storyline of the underwater metropolis, Rapture.

Like the first game, the player will have to kill the Big Daddy to get the ADAM from the Little Sister. However, the "rescue" option is not immediately available. Instead, the player can either opt to "harvest" or "adopt" the Little Sister. If the player chooses to adopt, the Little Sister will ride on Delta's shoulder until she finds a body to extract ADAM from. When Delta lets her down, she will begin to harvest from the body, causing Splicers to swarm and attack. Though she cannot be killed, Splicers will interrupt the ADAM progress bar by attacking her, meaning the player will be under constant attack until the progress bar fills up. After the gathering mission is complete, Delta will receive some ADAM and she will get back on Delta's shoulders. When the player comes to a Little Sister Vent, they will again be given the choice to harvest or save the Little Sister.
