Classic PC RPG System Shock 2, without which there would be no BioShock series, was released in 1999. It never got an official sequel, but that hasnāt stopped fans from putting one together.
Itās called System Shock Infinite (cute), and while sharing the same location gives you an all-new story, which kicks off right after the end of the System Shock 2.
There are audio logs, crew members and multiple plotlines, along with the return of System Shock 1ās cyberspace levels.
