System Shock: Enhanced Edition The station is SHODAN's now

You wake from a six-month coma on a corporate research station and something is very wrong. The surgeons are gone, the halls are wrecked, and SHODAN, the AI meant to run Citadel, has repurposed everyone aboard into cyborgs, robots and worse. The story unfolds through emails and audio logs you find as you explore, and it keeps moving: every time you think you have foiled SHODAN's plan, she is already a step ahead. The cat-and-mouse between you and her is the heart of the game, and her voice is one of the great villains of the era. This is the game that inspired BioShock, Deus Ex and Prey, and you can feel the lineage everywhere.

This is not a run-and-gun shooter. You are a hacker with a lead pipe and a pistol, not a superhuman, and charging headfirst into a room gets you killed fast. The lean move is your best friend: peek around a corner, take a shot, duck back before anything answers. Enemies resist different damage types, so you swap between bullets, teflon rounds, darts, energy weapons and a whole rack of grenades depending on what is shuffling toward you. Ammo is generous, health is not, and some areas respawn enemies, so every fight costs something. It is tense, deliberate, and it rewards thinking over reflexes.

Between the station's decks you jack into cyberspace, a wireframe world where you fly through corridors of colored grid, grab data and duel SHODAN's defense programs. It controls like a flight sim, complete with a roll axis, and it is unlike anything else in the game. Back on Citadel, the systems run deep: wire puzzles, rewired access panels, security cameras to destroy before SHODAN's minions overwhelm you, hardware attachments, energy shields, skates, even a jetpack. The interface looks like a cockpit from 1994 and takes some learning, but once it clicks you have more agency than in most modern games.
