With the release of BioShock: Infinite and its impressive reviews, there's never been a better time to rustle up odds and ends from the franchise. Case in point: A ridiculously rare functional BioShock audio diary is currently up for grabs.
The eBay auction is slated to close on March 31, so collectors don't have long to bid.
How rare is this audio diary exactly? According to gameshirts702, the seller, there's only a grand total of four of these out in the wild. All of them were created as part of a viral marketing effort for the release of BioShock 2. You might remember a little ARG called There's Something in the Sea, and the audio diaries are a direct result of jumping through all of those hoops.
Unfortunately, the seller has fallen on hard times financially, and the precious audio diary -- which has been kept in a glass box all this time -- will hopefully help alleviate this burden. Given that the auction's up to $1,675 as of writing, he or she has a pretty good chance.
So what, exactly, are you getting if you bid on this wonderful gadget? The video above shows it in action.
