By the way, if you want to play a game that's more of a spiritual successor to system shock/2 then even BioShock, play prey from 2017. Severely underrated game for the time. The amount of player choice you get is insane, then feels insanely tense because one of the basic enemy types can transform into everyday objects around the game world, so you're always going around wondering if that chair in the corner is actually a chair or if that teacup on the desk is actually a teacup. Really drives home the paranoia.
