And old Humble key (that I just revealed) for an excellent game!
On Humble Bundle it just says "Bioshock", but as that was not available as a choice here, and since it says on the Steam page of Bioshock that "Buying BioShock™ also gets you BioShock™ Remastered", this should represent what you will receive. However, please let me remove it if something is wrong. Best of luck to you all!
