Code Book front back

A Code Book is a special item found in BioShock Infinite. They can be found in certain hidden spots within Columbia and are required to translate the Vox Cipher which leads to valuable loot.

BioShock InfiniteEdit

In her isolation, Elizabeth has studied codes and cryptography. With the specialized code book, she can translate the Vox Cipher. Vox Cipher code books show up three times during BioShock Infinite.

The first cipher is near a photo handily pointing out the location of the Code Book. For the rest of the ciphers, if the Code Book is not yet found, Elizabeth will suggest a likely place to search.
