Ken Levine's System Shock 2 was released to mediocre sales, but later received critical acclaim and influenced subsequent first-person shooter game design.

Kenneth M. Levine is an American video game developer. He is the creative director and co-founder of Ghost Story Games. He led the creation of the BioShock series and is also known for his work System Shock 2.

System Shock 2 is a 1999 action role-playing survival horror video game designed by Ken Levine and co-developed by Irrational Games and Looking Glass Studios. Originally intended to be a standalone title, its story was changed during production into a sequel to the 1994 game System Shock. The alterations were made when Electronic Arts—who owned the System Shock franchise rights—signed on as publisher.

A first-person shooter (FPS) is a video game centered on gun fighting and other weapon-based combat seen from a first-person perspective, with the player experiencing the action directly through the eyes of the main character. This genre shares multiple common traits with other shooter games, and in turn falls under the action games category. Since the genre's inception, advanced 3D and pseudo-3D graphics have proven fundamental to allow a reasonable level of immersion in the game world, and this type of game helped pushing technology progressively further, challenging hardware developers worldwide to introduce numerous innovations in the field of graphics processing units. Multiplayer gaming has been an integral part of the experience and became even more prominent with the diffusion of internet connectivity in recent years.
