Bioshock 2 has been pulled from Steam stores along with Xbox Live and Playstation marketplace. The game which has now turned 5 years old seems to have disappeared from most online stores including Amazon and Apple's App Store.
Digital versions of the game along with it's downloadable content, including the Minerva's Den DLC, were pulled from all digital stores which has led to speculation that the games licensing deal must have expired.
A representative from 2K has made a statement via Reddit stating that the game will be making a return to digital stores soon. Their official statement below explains that the game will return and that neither single or multiplayer modes are affected by this, however no explanation was given as to why the game was pulled from online stores:
"BioShock 2 has been temporarily removed from the Steam, Xbox Live, and PlayStation Network marketplaces and will return to these digital stores soon. We'll let you know when that happens. In the meantime, this in no way affects the single-player or multiplayer experience for those who currently own BioShock 2."
The weird thing is, now that the game has been de-listed, I really want to play it!
