BioShock is considered the spiritual successor of System Shock 2 and mixes first-person shooting with role-playing elements. In the year 1960 a plane crashes in the middle of the Atlantic Ocean with you as the only survivor. You have the apparent luck of resurfacing in front of what looks like a door to an underwater complex. Without hesitating, you enter the door and soon you are taught that this is the city of Rapture, a paradise of free will build in the 40s by Andrew Ryan, visually and socially inspired by objectivism of Ayn Rand. However, even before you assimilate all this new information, the descent to this supposed paradise ends and you only see ruins and chaos. Learning about the destiny of Rapture will be now your main motivation while you have to survive to the horrors that the free will can create.
