The most obvious similarity between Bioshock and Bioshock Infinite is in the archetypes their characters adopt. Jack and Booker in particular share a great amount of character traits. Both are strangers in a strange land, thrust from the normal into the fantastic. Both have issues with memory: Jack’s memories of his family are completely manufactured, and, due to issues with dimensional travel, Booker’s fractured memories have blocked his sale of Anna and replaced it with a mission to find Elizabeth to wipe away his debt. Both possess an unknown but direct connection to their antagonist: Jack is Ryan’s son, and Booker actually is Comstock. Jack and Booker both carry physical markings of their past: Jack bears tattoos of chains on his wrists, and Booker has branded the initials “AD” on his right hand in regret for selling Anna.
Side antagonists also fit into archetypes. Frank Fontaine of Rapture and Daisy Fitzpatrick of the Vox Populi are both potential allies of the protagonist who eventually betray them. Fontaine attempts to kill Jack, and the Daisy of an alternate reality attempts to kill Booker because of what he represents to her — in her reality, Booker died on behalf of the Vox Populi, and his reappearance threatens to destroy the figure of martyrdom Daisy has built around Booker’s death.
There is also a strong correlation between the mad artist Sander Cohen and the war-obsessed soldier Cornelius Slate. Both are hell-bent on their goal: Cohen yearns to see his sick masterpiece–a collection of pictures of his dead ex-disciples–completed, and Slate and his men desire to die “a soldier’s death” at the hands of Booker, rather than of Comstock.
In addition, both games have a strong archetype of the scientist searching for redemption for the horror caused by their creation. In Bioshock, Dr. Brigid Tenenbaum is the scientist responsible for the creation of ADAM, the material which allows for the gene-altering plasmids to exist. However, this ADAM must be grown within Little Sisters, orphaned girls whose minds are twisted by the ADAM-producing sea slugs that live inside them. Tenenbaum spends the entirety of the game attempting to save the Little Sisters, giving Jack a special concoction that frees them from their altered state. Similarly, the Luteces–two versions of the same person from two realities–attempt to set right the mess they’ve created by allowing Comstock to take Anna from Booker’s reality. To accomplish this, they bring Booker to the reality of Columbia to save Elizabeth.
With all of these similarities, at first the character of Elizabeth seems to stick out as an unmatched character. However, upon scrutiny one realizes that Elizabeth is actually a variation of a Little Sister: she is involuntarily given certain abilities, and she is watched over by a mechanical monstrosity–Songbird. Songbird is heavily reminiscent of the Big Daddies which protect the Little Sisters in Bioshock; a few voxophones in Infinite even imply that the creators of Songbird and the mechanical Handymen of Columbia were inspired by images of Big Daddies seen through tears inadvertently caused by Elizabeth.
As for the themes of the games, the questioning of memories and identity are obvious ones, as well as how societies are created and destroyed, often with consequences of experimentation reminiscent of Mary Shelly’s Frankenstein thrown in. However, perhaps the most poignant of the themes present in these games are the depictions of patricide and impersonal suicide.
In both games, the protagonists are either the cause of or victim of patricide, where the victim is a somewhat willing party. In Bioshock, Jack kills his father Andrew Ryan by his own orders, for Ryan would rather die of his own free will than at the hands of Atlas. In Infinite, Booker appears to allow Elizabeth’s drowning of him so that Comstock will never come to be (it should also be noted that the threat of drowning is a nice bookend to both games: Bioshock begins with Jack frantically struggling to reach the surface of the ocean after his plane crashes, and Infinite ends with Booker’s drowning).
Both protagonists also commit a sort of indirect, symbolic suicide. It is implied that Jack is not only Ryan’s son, but almost a clone of him, making his patricide also a sort of suicide. In Infinite, Booker kills Comstock, his alternate self, in a fit of rage. Of special note is the method of murder: Jack kills Ryan by bludgeoning him in the head with his gold club, and Booker slams Comstock’s head on a baptismal font several times before drowning him. In both cases, the antagonist is slain due to blunt force inflicted on the head through a personal object–Ryan’s golf club and Comstock’s baptismal font (Booker’s drowning of Comstock also serves an effective foreshadowing of Booker’s future drowning).
But while these two games share a large amount of themes and archetypes, they are decidedly different. Bioshock is the story of a city gone mad, where its citizens will commit any act to come out on top. It is dark, gritty, and horrifying, with the protagonist utterly alone under the ocean. But where Bioshock is dark, Bioshock Infinite is bright, contrasting the idyllic land of Columbia with the disturbing belief system it supports; where Jack is alone, Booker is aided by Elizabeth, creating one of the greatest player-to-NPC relationships in recent gaming memory. Whatever the next Bioshock game is about, it is guaranteed to be its own game, while still reflecting the themes established by Bioshock years before.
