Jack - BioShock

The Crash (1960)

Jack's story begins with a plane crash over the Atlantic Ocean. He is the sole survivor, swimming toward a lighthouse rising impossibly from the waves.

Inside, a bathysphere descends into the depths—revealing the impossible city of Rapture.

Rapture

An underwater city built by Andrew Ryan in the 1940s. A place where the artist would not fear the censor, where the scientist would not be bound by petty morality.

Now it lies in ruins, torn apart by civil war and madness.

Andrew Ryan

The Founder:

His Fall:

Atlas

A voice on the radio guiding Jack through Rapture. He claims to be fighting Ryan's tyranny, trying to save his wife and child.

Plasmids

Gene-altering serums that grant superhuman powers—at a terrible cost.

ADAM & EVE

Little Sisters

Young girls implanted with sea slugs, turned into ADAM harvesters. They see Rapture as a paradise, the corpses as "angels."

Jack must choose: harvest them for power, or save them from their fate.

Big Daddies

Hulking figures in diving suits, grafted to their armor. They exist only to protect the Little Sisters.

Types encountered:

1. Would You Kindly

Three words that control Jack absolutely. A trigger phrase implanted in his mind. Every "choice" he made was commanded by Atlas.

2. Jack's Origin

Jack is not a survivor by chance. He is Andrew Ryan's illegitimate son, bought by Fontaine, genetically modified to age rapidly and obey without question.

3. Frank Fontaine

Atlas was never real. He is Frank Fontaine—smuggler, criminal mastermind, and the man who created Jack as a weapon to kill Ryan and seize Rapture.

4. A Man Chooses

Ryan forces Jack to kill him with a golf club, proving his point: Jack is a slave, not a man. He never had free will—until now.

5. Breaking Free

Dr. Tenenbaum removes the conditioning. For the first time, Jack can choose. Hunt Fontaine—not because he's told to, but because he wants to.

6. The Endings

Save the Little Sisters, and Jack finds redemption—a family, a life, and peace. Harvest them, and he becomes the monster Rapture created. The choice was always his.

Summary

Jack's journey through Rapture is a meditation on free will and control. Built to be a weapon, he discovers humanity in the depths of madness. BioShock asks: if you don't know you're being controlled, are you truly free? Jack's answer is written in the choices you make.

"We all make choices, but in the end our choices make us." — Andrew Ryan
