The original BioShock was released in 2007 and used a heavily modified Unreal Engine 2.5 with some of the advanced technologies from Unreal Engine 3. The game title looked good and the underwater city of Rapture was well known by gamers around the world. What would BioShock look like if run on Unreal Engine 4? YouTube user noodlespagoodle gathered some assets from the original game and put them into the Unreal Engine 4 game engine. The port over to UE4 wasn't exactly perfect, but the game looks pretty damn good. Irrational Games is long gone, but it would be cool if 2K would release a ported version of the original BioShock powered by the new Unreal Engine 4.
The video that showcases a Big Daddy, as well as various scenes in Rapture. can be seen below.
