BioShock Infinite didn't just have a crazy story and interesting gameplay, the developers also found the time to hide a number of Easter Eggs throughout the experience. Here are the ones that have been found so far.

Konami Code

First off, the classic Konami code makes a small but fun appearance. Inputting the code on the Xbox version's menu screen (up, up, down, down, left, right, left, right, B, A), will unlock 1999 mode. PlayStation 3 gamers should input up, up, down, down, left, right, left, right, O, X; while PC players should exchange the O, X for cancel and confirm. 1999 mode is the hardest difficulty in the game, and can also be unlocked by completing a playthrough on one of the easier modes.

Snight

If you head into the graveyard with Lady Comstock's mausoleum, you can find a tombstone engraved with the word "SNIGHT." Mike Snight is one of the environment designers for the game.

The Wrench

The wrench from the original BioShock also makes an appearance, you can find it on the ground near a broken vending machine, right after collecting the Murder of Crows vigor.

Romeo and Juliet

During the fair scene at the beginning of the game, you can find a creepy hidden message after drinking your first vigor, Possession. Reversing the audio reveals the line, "when I shall die, take him and cut him out into little stars." This is a quote from Romeo and Juliet, fitting considering the Hamlet and King Leer references that also appear in the game.

Play the Guitar

This one might not actually be an Easter egg, as it seems the designers wanted you to find it. But if you happened to miss it, there's a guitar in the basement of the bar in Shantytown. Interacting with it causes Booker and Elizabeth to perform a cute little rendition of " Will the Circle Be Unbroken."

Anachronistic Music

And of course, there's plenty of great music to discover. Some of the examples include a Barbershop Quartet version of the Beach Boys when you first enter the main part of Columbia, Cyndi Lauper's "Girls Just Wanna Have Fun" in Battleship Bay, and Creedence Clearwater Revival's "Fortunate Son" in Finkton.
