This deal comes to us as a surprise! The original copy of Bioshock FREE via GameFly. You do need to create an account with them (you don’t need their service though) and you will need to download their client as well.
That being said, GameFly also stated that there are only a limited number of digital downloads for this so get it while you can!
Sure its a 5 year old game, but it is still a great game to have in your library if you don’t own it already.
