BioShock 2 free Mac Game

BioShock 2 is set in the fictional city of Rapture, an underwater metropolis hidden from the rest of the world. Rapture was the realized vision of Andrew Ryan, who built the city to escape the tyranny of governments. Despite the apparent utopia, class distinctions grew, and former gangster and businessman Frank Fontaine used his influence of the lower class to plan a takeover of Rapture. Fontaine created black market routes with the surface world, and together with Dr. Brigid Tenenbaum, created a cheap plasmid industry by mass-producing ADAM through the implanting of the slugs in the stomachs of orphaned girls, nicknamed "Little Sisters". Fontaine used his plasmid-enhanced army to attack Ryan, but reportedly was killed in the battle.

Ryan took the opportunity to seize his assets including the plasmid factories. In the months that followed, a second figure named Atlas rose to speak for the lower class, creating further strife. Atlas led attacks on the factories housing the Little Sisters, and Ryan countered by creating "Big Daddies", plasmid-enhanced humans surgically grafted into giant lumbering diving suits who were psychologically compelled to protect the Little Sisters at all costs. Ryan created his own army of plasmid-enhanced soldiers, named "Splicers", which he controlled using pheromones distributed through Rapture's air system. Tension came to a head on New Year's Eve of 1958, when Atlas ordered an all-out attack on Ryan. The battle left many dead, and the few sane survivors barricaded themselves away. What once was a beautiful utopia had fallen into a crumbling dystopia.

Plot

BioShock 2 opens on New Year's Eve, 1958, as Subject Delta patrols Rapture with his Little Sister, Eleanor. Eleanor is separated from Delta by her mother, Sofia Lamb, who uses a mind control plasmid on Delta to make him shoot himself. Ten years later, Delta awakens, revived by Little Sisters under the control of Eleanor. Delta is drawn towards Eleanor by their past Big Daddy-Little Sister connection. Brigid Tenenbaum encounters Delta, and explains that unless Delta reunites with Eleanor, he will fall into a coma. With the help of the Little Sisters under Eleanor's control and Tenenbaum's ally, former entrepreneur Augustus Sinclair, Delta makes his way towards Lamb's stronghold. Traveling through the city, Delta encounters members of the Rapture family such as Grace Holloway, a singer who had suffered under Ryan's unjust laws against revolt; Stanley Poole, a con artist who had murdered many of the Family's members in Dionysus Square after foolishly trying to cover up his blunders from Lamb; and Gil Alexander, a respected scientist who worked at Fontaine Futuristics before Lamb transformed him into an encased monstrosity of flesh, who he can kill or spare, and learns Lamb's plan: she seeks to use ADAM to transform Eleanor into a perfect embodiment of her altruistic ideals. Lamb's ultimate goal is to have the collected minds and memories of everyone in Rapture become a part of Eleanor through the use of the genetic memory in ADAM, thus making her an "Embodiment of the Family" which Lamb believes will put an end to "The Self".

Delta arrives at a containment chamber where Eleanor is held, but Lamb captures him and severs his bond with Eleanor by temporarily stopping her heart. Though Eleanor survives, Delta begins to slowly die as the bond cannot be re-established. Using a Little Sister, Eleanor transforms herself into a Big Sister and breaks Delta from confinement. Together they head for an escape pod that Sinclair has arranged to leave Rapture. The two find that Lamb has converted Sinclair into Subject Omega, declaring that Delta should be what Sinclair is now, and Delta is forced to finish him off. After a final climactic showdown with the remnants of The Rapture Family in order to buy time for Eleanor to prepare the pod, Delta is forced to flood the area and escape in his suit. Eleanor and Delta make it to the escape pod but a bomb set by Lamb leaves Delta mortally wounded. Eleanor teleports and reaches the escape pod before the bomb blows, while Delta manages to grab onto the pod's side and climb aboard as it rises.

The game's ending depends on how the player interacted with the Little Sisters, and the fates of Holloway, Poole and Alexander within the game. Eleanor can save Sofia Lamb or force her to drown, depending on whether the player spared or executed the non-player characters. If Delta rescued all of the Little Sisters he will breathe his last breath in Eleanor's arms, the weather will be sunny and clean, then she will absorb his personality and memories and leave Rapture with the Little Sisters to change the world for the better, dropping the doll that one of the little sisters gave her in the ocean, which slightly resembles Delta, in order to mourn his death, and to make his death count. If Delta harvested all of the Little Sisters then Eleanor will extract Delta's ADAM and become bent on world domination, the weather becoming dark and stormy as the corpses of Rapture's inhabitants float to the surface. A mix between rescuing and harvesting the little sisters gives the player a choice; either Eleanor can absorb his ADAM and become evil, or Delta can stop her and die, in which case Eleanor will mourn his death and make her own way in life.
