When this came on sale for 50 bucks i couldnt help myself being an avid fan of bioshock. Im sure you all know how the game goes by now so i will get into the special edition stuff. First is the box, its well constructed nice and solid and a great paintjob of a butterfly made from little little sisters hands. Second is the record of the soundtrack, i havent listened to it due to not owning a record player but its a great touch to add to the steampunk/art deco of the game. Next up is the posters they are great too as i am sure i have seen them in the game somewhere and also have hidden messages revealed under a blue light (google it!) The book called deco devolution is very comprhensive with art and concepts and is hard back too which is great and lastly there is the cd of the soundtrack which is really haunting and looks like an old record too! so all in all if you see this on sale again i really recommend getting it as you will not regret it at all!!
