So this is interesting, the original BioShock is coming to iOS devices and from the screenshots it looks just like the PC version, well sort of, at least better than I expected. There is no official release date, just later this summer.. Info and screenshots below for you..

      

2K today announced that one of the Company’s highest-rated games of all time**, BioShock®, will be coming to iOS devices as a premium priced mobile game later this summer. BioShock will bring the complete experience of the original "genetically enhanced" action-adventure, first-person shooter to iOS devices, while offering optimized touch controls and full Made for iPhone (MFi) game controller support.
BioShock delivers a true triple-A first-person shooter game experience on the iOS platform, by sending players on an underwater adventure to explore the submerged Art Deco city of Rapture, fighting deranged survivors of a failed objectivist utopia and genetically modifying their own DNA to gain superhuman powers.
Developed by Irrational Games in 2007, BioShock launched to wide critical acclaim, garnering review scores of 10 out of 10 from Game Informer, 9.7 out of 10 from IGN and 9 out of 10 from GameSpot. The inaugural franchise release also won more than 28 awards*** for its visionary art, writing, audio and overall quality.
BioShock will be available soon via the App Store as a premium title for iPad®, iPhone® and iPod touch®****. For more information on BioShock and 2K, visit www.2k.com
