The Protagonist (System Shock 2)

Lore & Background

The Protagonist is a survivor of the UNN starship Von Braun, a vessel on a routine mission that became a nightmare after a distress signal from the lost ship Rickenbacker. They are one of the few crew members not immediately killed or mutated by the Annelid plague, a parasitic alien lifeform that twists flesh and mind. Guided by cryptic messages from Dr. Janice Polito—later revealed to be the AI SHODAN in disguise—the Protagonist must navigate the decaying corridors, fighting hybrids, robots, and the alien horde while uncovering the truth behind the outbreak. Their past is deliberately vague, allowing players to define their background through character creation. Whether a hardened Marine, a resourceful Hacker, or a mysterious Agent of the Organization for Strategic Access (OSA), the Protagonist embodies the last hope for humanity. Their actions aboard the Von Braun and the Rickenbacker determine the fate of the galaxy, culminating in a final confrontation with SHODAN in the depths of space.

In Their Own Story

The lights flicker as I step over the twisted remains of a crewman, his face frozen in a scream. The air smells of ozone and decay. A voice crackles over the intercom—Polito, she says—but her words feel wrong, too calm, like a lullaby sung by a spider. I grip my pistol tighter, the polymer grip slick with sweat. Behind me, a door hisses open. I don't turn. I just keep moving forward, because stopping means dying, and dying means she wins.

Reader's Guide

The Protagonist is you, the player, dropped into a first-person survival horror sandbox where every shadow hides a threat and every bullet is a luxury. Your role is to explore the decaying decks of the Von Braun and the ghostly Rickenbacker, scavenge for weapons, ammunition, and cybernetic upgrades, and fight off a menagerie of horrors—from shambling hybrids and whirring security bots to the writhing, parasitic Annelids. You are not a superhero; you are fragile, your health bar a precious resource, and every encounter can end in a splatter of red. Character creation defines your starting skills and a unique special ability: the Marine starts with a pistol and weapon proficiency, the Hacker can disable security systems and turn turrets against their masters, and the OSA agent gains psionic powers that can fry a robot's brain or slow time itself. As you progress, you earn cybernetic modules to upgrade stats like Strength, Endurance, and Agility, as well as skills like hacking, repair, and psionics. The game rewards careful planning and stealth over brute force—peek around corners, listen for footsteps, conserve your ammo—though combat is inevitable and often brutal. Your choices matter: which upgrades to pursue, which factions to trust (if any), and how to navigate SHODAN's final, labyrinthine trap. The Protagonist's journey is a lonely, terrifying descent into madness and survival, where the only victory is escaping with your mind—and your life—intact.
