Click to viewThis is Nathan. While the rest of you were off being giddy about playing as Big Daddy in Bioshock 2, Nathan was building himself a costume that lets him play as Big Sister in real life. Now that's commitment.

It's the designer's second Bioshock costume: two years ago he made a similarly impressive Big Daddy get-up. And as you can see, a DIY Big Sister costume isn't for the faint of heart: corsets and leg braces are just the beginning. But if you're a truly dedicated gamer—or a truly deranged costume enthusiast—it doesn't get much better than this. If you start yours now, you've got an outside shot of having it ready by Halloween.
