Booker DeWiitt, the ex-Pinkerton Agent Bioshock Infinite protagonist, has been revealed by Irrational Games.
As you can see, Booker is every bit the 37 year old, haggard, burned out private investigator he's supposed to be. He is 6 feet in height and weighing 195 pounds, with green eyes and a scar above the right eye. He doesn't look anything like his poster, though.
Marvel Comics fans will recognize the parody of The Uncanny X-Men #141 cover in the picture as well.
