With Halloween just around the corner, the pressure of coming up with a cool costume is on. But maybe this will help - someone is selling a custom-made full scale Big Daddy helmet on eBay.

I can’t imagine anyone keeping the thing on all the way through the night without constantly knocking things over but this is something to own simply because of the coolness factor. After buying this, all you need is an old-school diver suit and your transformation into a bad-ass Big Daddy shall be complete.

The high bid at the time of writing was $250 so it won’t come cheap. But if you’re a big enough BioShock fan then that certainly shouldn’t stop you.
