This is the Bioshock Big Daddy Lunchbox available from ThinkGeek (among other places, but ThinkGeek has the best price that I saw - $15). It looks rusty, but it's not, it's brand new. Have you ever tasted rust before? It tastes like dried blood. Unfortunately, unlike all the lunchboxes I ever had as a kid, this one does not come with a matching thermos. That's not a deal breaker for me, just a disappointment. Bioshock is hands down one of my favorite video game franchises of all time. My brother and I used to take turns playing and I'd always have to toss him the controller to complete those 'connect the pipes' hacking mini-games because I suck under pressure. He was great under pressure, even with me yelling and beating him in the back of the head with a couch cushion. We never played after dark though because of Spider Splicers.
Thanks to Drumond, who agrees nothing spells success like a bitchin' lunchbox.
