IG Fun, developers of mobile phone gaming, have been hard at work translating BioShock from its console version to that of 2D and 3D versions for cells.
Before blowing this off as a trite excuse for a coat-tail moneymaker, know that 2K has been in constant communication with IG Fun throughout the game's development and has even contributed its own resources. Also, the entirety of the game's 16 chapters and both endings are included on the mobile version.
Moreover, the game looks surprisingly good. So good in fact, it is now being rumored that the title will likely release for the iPhone. However, confirmation of this from official sources has not been forthcoming.
