Irrational Games has hired Anna Moleva, the talented cosplayer with an uncanny resemblance to Elizabeth even without the costume, to represent the character in all of BioShock Infinite's marketing material.
Moleva will be representing Elizabeth from BioShock Infinite on the game's box art, at assorted events, and in an upcoming television commercial. You can find out more about Moleva and her Elizabeth costume at Irrational Games' official website.
