This page contains information on Easter Eggs and Secrets in BioShock Infinite, including secret codes and hidden references to other media.

In the beginning of the game, among the carnival games where you first get the Possesion Vigor, the Vidi Vici Vigor machine shows Bucking Bronco (4) for sale, which is left over from the earlier E3 build of the game, in which Vigor bottles would give you a certain number of charges.

Secret Background Music

During seemingly music-less stretches of BioShock Infinite, an extremely slowed-down song is played in the background noise. When sped up, voices can be heard on this mysterious musical track.

1999 Mode

1999 Mode is an unlockable game mode in BioShock Infinite. Activating it significantly increases the challenge of the game. According to Irrational Games creative director Ken Levine, "[Average gamers] are gonna hate this mode. That's okay — it's not for them." He also warns, "This mode is not going to feel like BioShock." You can unlock 1999 Mode by beating the game or by inputting the Konami Code (see below).

Konami Code

Wrench from BioShock



The Wrench, your trusty weapon in the original BioShock, can be found in BioShock Infinite. It's located just after acquiring the Murder of Crows Vigor, sitting next to a piece of Gear. The Wrench can also be seen on the First Lady Airship in which Elizabeth uses to attack Booker.

Pistol in the Baby Carriage



At the beginning of Battleship Bay, after waking up, and walking through the first hallway, you can find pistol ammo in a baby carriage. This is a reference to the original BioShock when you find the pistol in a baby carriage.

There is also a Hand Cannon in a baby carriage next to a dead woman in Emporia, a reference to the revolver in the original. This can be found by a locked shop in a fire, between Memorial Garden and Market District, near where the secret song on this level is.

Secret Song Covers



BioShock Infinite contains a number of anachronistic song covers like "God Only Knows" by the Beach Boys, "Girls Just Wanna Have Fun" by Cyndi Lauper and "Fortunate Son" by Creedence Clearwater Revival.

Tthere is a sequence where booker plays guitar and elizabeth sings the song.the song is "will the circle be unbroken" and it happens in the shantytown's graveyard shift bar.owner might get hostile if you tried to access the room with guitar.this is same song showed in the end credits played by the booker and elizabeth's voice actors.

there is also a scene which occurs in the tear when you turn out to be a martyr and are in shantytown.near graveyard shift bar few vox populis are taking photos with a dead handyman.

BioShock Development Reference

When Elizabeth enters the Duke and Dimwit game room in Battleship Bay, she talks about the latest version of the game being "delayed three times". This is a self-reference to the game itself, which was delayed three times.

Saltonstall Reference

Saltonstall was a figure in BioShock Infinite's original 2010 gameplay demo who was running for political office. While he doesn't appear in the final game, you can hear a NPC talk about him right when Booker gets to New Eden Square.

He is again referenced after the Vox Populi take over Columbia. Booker and Elizabeth discover a wall covered in scalps labeled with the names of prominent members of the city, including Saltonstall. While he is never seen in-game, he surely met a grisly death at the hands of the Vox.

Lutece Twins Easter Egg

Right after Booker first sees the Monument Island statue and receives the telegram from Lutece, approach the telescope to the left and look through it. Toward the bottom left you will see the twins, Robert juggling and Rosalind watching. Exit the telescope and they are nowhere to be seen. Re-Enter the Telescope and they are still gone.

Another easter egg can be seen with the Rosalind statue towards the beginning of the game. When you first look up at it, it appears to look like a tear that Elizabeth can bring forth, but it changes on its own and becomes Robert.

Revival Scene

When Elizabeth revives Booker, she holds a needle and injects him with a substance, in a similar way to how the little sisters in Bioshock remove ADAM.

Original Bioshock Reference

At the beginning of the game the man who baptizes you, Preacher Whitting, echoes the phrase "Is it someone new?", the same phrase mentioned by a Splicer at the beginning of the original Bioshock.

Reference to Bryce DeWitt: Theoretical Physicist



Booker DeWitt's name is a reference to theoretical physicist Bryce Dewitt. Bryce Dewitt was an adherent to the many worlds interpretation of quantum mechanics and advanced the formulation of Hugh Everett's Many Worlds Theory.

The Looking Glass Keycode



There is only one door with a number lock in the entire game - the code is 0451. This code was the number to the offices of Looking Glass Studios, who created System Shock and Thief, as a reference to Fahrenheit 451. It can be found in games that share the Looking Glass style of game design, usually as the first key code in the game. Recent titles that have used the code include Deus Ex: Human Revolution, Dishonored, and Bioshock.

Disneyland Reference

If you look at the map after getting off the skyline before going into the "Hall of Heroes" it is similar to a map of Disney Land.

Star Wars Reference

Look for a poster when making it to "the girl in the monument". Keep your eyes peeled for a Star Wars reference to Revenge of the Jedi; this was the title on the very first Star Wars Episode VI poster before it was decided that the word revenge was not appropriate. Also listen for a peculiar song just before hand in the room with the giant speakers.

Booker then mutters the line, "This job is getting worse all the time", a reference to Star Wars Episode V: The Empire Strikes Back.

"I Married A Communist" Reference

When you first get to Columbia, right after the quartet singing "God Only Knows" you come upon a square with two children playing and a man and woman talking. The man is requesting the woman to keep "that kind of talk hushed up because it draws attention." The woman then replies: "Oh come now, don't turn into some Finkton radical on me, I don't want to be a character out of 'I Married A Vox Populi,' now do I?" This is a reference to the 1949 film "I married a Communist". The Vox are based on Communist ideals.

Original Bioshock Little Sister/Big Daddy Reference

During the scene when Daisy Fitzroy is holding the young boy hostage, Booker helps Elizabeth into a vent just as the Big Daddies help Little Sisters into the vents in the original Bioshock.

Surprise Cameo

This Easter egg occurs at the end of the game and is thus hidden behind spoiler tags on this page.

At the end of the game when you see lots of Elizabeths, One of them has the body shape of the first trailer for the game

Extra Scene After Credits

After beating the game, waiting until the credits end will allow you to explore Booker's room and get an extra scene.

Animal (Cat,Wolf,Unicorn) sketches/doodling in concrete steps outside Lighthouses, Easter Eggs.

I did not notice this until the end of the game when you are back at the multiple Lighthouses. I was looking around for any other Easter Eggs and I came across what looks like a Cat face of some sort drawn into the concrete step landing outside the Lighthouse door. I started looking at it closer and realized there are several drawings that you really have to pay attention to or they will just look like scratches in the concrete. To me there are specific Animal types but you can look for yourselves and see what each looks like to you.

Voxophone References To Rapture Universe

There are at least two voxophones that make references to the universe in which Rapture exists.

The first one entitled "A Child Needs a Protector" is by Jeremiah Fink and describes a glimpse he has gotten of a Big Daddy and Little Sister:'

"These holes have shown me yet another wonder! Though, I've yet to see the application for it. They illuminate a merger of machine and man that is somehow the lesser, yet the greater, of both parties! The process seems to be irreversible. Perhaps, though, Comstock will have some need of this kind of thing to keep watch in that tower he is building."

The comment about the "lesser, yet the greater, of both parties!" is referencing the fact that Big Daddies are the more physically imposing protectors of the Little Sisters who have a much greater overall importance to the world of Rapture as they are the harvesters of Adam.

'The second voxophone is entitled "Out of Thin Air" and is also by Jeremiah Fink. This is an admittedly more veiled reference to Tennenbaum in Rapture whom Fink has been observing:'

"Dear brother, these holes in the thin air continue to pay dividends. I know not which musician you borrow your notes from, but if he has half the genius of the biologist I now observe, well...then you are to be the Mozart of Columbia' "
