Without just copying and pasting Wikipedia content, I had the question posed to me in if there was any relationship between System Shock and Bioshock. Bioshock obviously being hugely inspired by SS, but I wasn’t sure and believed so, but given the convoluted history of SS games and their rights, actually checking the information is “kind of”.
Looking Glass studios, started by Paul Neurath and Ned Lerner, who developed some games with very similar themes and action:
Ultima Underworld: The Stygian Abyss
Ultima Underworld II: The Labyrinth of Worlds
Our titular game, System Shock
Thief: The Dark Project (and later) Thief Gold
System Shock 2 (co-developed)
Thief 2: The Metal Age
Paul Neurath eventually got the rights to Ultima Underworld and started a team called “OtherSide Entertainment” (as the other side of the looking glass) and made the poorly received Underworld Ascendant, and planed to do System Shock 3 afterwards, however, the publisher withdrew from the project.
System Shock 2 was co-developed by a company led by a person who you might recognize, Ken Levine, after working on Thief co developed System Shock 2, and the company was Irrational Games, responsible for Bioshock, Bioshock Infinite (not Bioshock 2), which is your admittedly tenuous link to Bioshock
