System Shock 2 is a 1999 action role-playing and 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.
The game takes place on board a starship in a cyberpunk depiction of 2114. The player assumes the role of a soldier trying to stem the outbreak of a genetic infection that has devastated the ship. Like System Shock, gameplay consists of first-person combat and exploration. It incorporates role-playing elements, in which the player can develop skills and traits, such as hacking and psionic abilities.
System Shock 2 was originally released in August 1999 for Microsoft Windows. The game received critical acclaim but failed to meet commercial sales expectations. Many critics later determined that the game was highly influential in subsequent game design, particularly on first-person shooters, and considered it far ahead of its time. It has been included in several greatest games of all time lists. In 2007, Irrational Games released a spiritual successor to the System Shock series, titled BioShock, to critical acclaim and strong sales.
System Shock 2 had been in intellectual property limbo following the closure of Looking Glass Studios. Nightdive Studios were able to secure the rights to the game and the System Shock franchise in 2013 to release an updated version of System Shock 2 for modern operating systems, including for OS X and Linux, and released a 25th anniversary remaster of the game in 2025. OtherSide Entertainment announced in 2015 that they had acquired the rights from Nightdive Studios to produce a sequel, System Shock 3, but as of 2020 the rights have since been transferred to Tencent.
Gameplay
As in its predecessor, System Shock, gameplay in System Shock 2 is an amalgamation of the action role-playing game and survival horror genres. The developers achieved this gameplay design by rendering the experience as a standard first-person shooter and adding a character customization and development system, which are considered signature role-playing elements. The player uses melee and projectile weapons to defeat enemies, while the role-playing system allows the development of useful abilities. Navigation is presented from a first-person view and complemented with a heads-up display that shows character and weapon information, a map, and a drag and drop inventory.
The backstory is explained progressively through the player's acquisition of audio logs and encounters with ghostly apparitions. At the beginning of the game, the player chooses a career in a branch of the Unified National Nominate, a fictional military organization. Each branch of service gives the player a set of starting bonuses composed of certain skills, though may thereafter freely develop as the player chooses. The Marine begins with bonuses to weaponry, the Navy officer is skilled in repairing and hacking, and the OSA agent gets a starting set of psionic powers.
The player can upgrade their skills by using "cyber-modules" given as rewards for completing objectives such as searching the ship and spend them at devices called "cyber-upgrade units" to obtain enhanced skills. Operating system (O/S) units allow one-time character upgrades to be made (e.g. permanent health enhancement). An in-game currency called "nanites" may be spent on items at vending machines, including ammunition supplies and health packs. "Quantum Bio-Reconstruction Machines" can be activated and reconstitute the player for 10 nanites if they die inside the area in which the machine resides. Otherwise, the game ends and progress must be resumed from a save point. The player can hack devices, such as keypads to open alternate areas and vending machines to reduce prices. When a hack is attempted, a minigame begins that features a grid of green nodes; the player must connect three in a straight row to succeed. Optionally, electronic lock picks, called "ICE-picks", can be found that will automatically hack a machine, regardless of its difficulty.
Throughout the game, the player can procure various weapons, including melee weapons, pistols, shotguns, and alien weapons. Non-melee weapons degrade with use and will break if they are not regularly repaired with maintenance tools. There are a variety of ammunition types, each of which is most damaging to a specific enemy. For example, organic enemies are vulnerable to anti-personnel rounds, while mechanical foes are weak against armour-piercing rounds. Similarly, energy weapons cause the most damage against robots and cyborgs, and the annelid-made exotic weaponry is particularly harmful to organic targets. Because ammunition is scarce, to be effective the player must use it sparingly and carefully search rooms for supplies.
The game includes a research function. When new objects are encountered in the game, especially enemies, their organs can be collected; when combined with chemicals found in storage rooms, the player can research the enemies and thus improve their damage against them. Similarly, some exotic weapons and items can only be used after being researched. OSA agents effectively have a separate weapons tree available to them. Psionic powers, such as invisibility, fireballs, and teleportation, can be learned.
Plot
Backstory
In 2072, after the Citadel Station's demise in System Shock, TriOptimum's attempts to cover up the incident were exposed to the media, and the corporation was brought up on charges from multiple individuals and companies for the ensuing scandal. The virus developed there killed the station's population; the ruthless malevolent AI supercomputer named SHODAN controlled the Citadel Station in hopes of enslaving and destroying humanity. After a large number of trials, the company went bankrupt, and its operations were shut down. The United Nations Nominate (UNN), a successor to the UN, was established to combat the hostility and corruption of power-hungry corporations, including TriOptimum. Artificial intelligence was reduced to the most rudimentary of tasks to prevent the creation of another SHODAN-like malevolent AI.
In 2100, 28 years later, the company's failed stocks and assets were bought by a Russian oligarch named Anatoly Korenchkin, a former black market operator who sought to make money legitimately. He re-licensed and restored the company to its former status in the following decade. Along with producing healthcare and consumer products, Korenchkin signed weapons contracts with various military organizations, private and political-owned. The new UNN was virtually powerless, with Korenchkin exercising control over them.
In January 2114, 42 years after the Citadel events and 14 years into rebuilding TriOptimum, the company created an experimental FTL starship, the Von Braun, which is on its maiden voyage. The ship is followed by a UNN space vessel, the Rickenbacker, controlled by Captain William Bedford Diego, son of the Citadel Station's infamous commander, Edward Diego, and public hero of the Battle of the Boston Harbor during the Eastern States Police Action. Because the Rickenbacker does not have an FTL system, the two ships are attached for the trip. However, Korenchkin was egotistical enough to make himself the captain of the Von Braun despite being inexperienced.
Five months into the journey, the ships respond to a distress signal from the planet Tau Ceti V, outside the Solar System. A rescue team is sent to the planet's surface, where they discover strange eggs; these eggs, found in an old ejection pod, infect the rescue team and integrate them into an alien communion known as "the Many" - a psychic hive mind generated by parasitic worms which can infect and mutate a human host. The parasites eventually spread to both ships and take over or kill most of their crews.
Story Owing to a computer malfunction, the remaining soldier awakens with amnesia in a cryo-tube on the medical deck of the Von Braun, being implanted with an illegal cyber-neural interface. Another survivor, Dr. Janice Polito, contacts and guides him to safety before the cabin depressurizes. She demands that he meets her on deck 4 of the Von Braun. Along the way, the soldier battles the infected crew members. The Many telepathically communicate with him, attempting to convince him to join them. After restarting the ship's engine core, the soldier reaches deck 4 and discovers that Polito is dead and is soon confronted by SHODAN. It is revealed she has been posing as Polito to gain the soldier's trust.
SHODAN mentions that she is responsible for creating the Many through her bioengineering experiments on Citadel Station. The Hacker, who freed her from her ethical restraints, ejected the grove that contained her experiments to prevent them from contaminating Earth, an act that allowed part of SHODAN to survive in the grove. The grove crash-landed on Tau Ceti V. While SHODAN went into forced hibernation, the Many evolved beyond her control. SHODAN tells the soldier that his only chance for survival lies in helping destroy her creations. Efforts to regain control of XERXES, the main computer on the Von Braun, fail. SHODAN informs the soldier that destroying the ship is their only option, but he must transmit her program to the Rickenbacker first. While en route, the soldier briefly encounters two survivors, Thomas "Tommy" Suarez and Rebecca Siddons, who flee the ship aboard an escape pod.
With the transfer complete, the soldier travels to the Rickenbacker and learns both ships have been enveloped by the infection's source, a gigantic mass of bio-organic tissue that has wrapped itself over the two ships. The soldier enters the biomass and destroys its core, stopping the infection. SHODAN congratulates him and tells of her intentions to merge real space and cyberspace through the Von Brauns faster-than-light drive. The soldier confronts SHODAN in cyberspace and defeats her. The final scene shows Tommy and Rebecca receiving a message from the Von Braun. Tommy responds, saying they will return and noting that Rebecca is acting strange. Rebecca speaks in a SHODAN-like voice, asking Tommy if he "likes her new look" as the screen fades to black.
History
Development
Development of System Shock 2 began in 1997 when Looking Glass Studios approached Irrational Games with an idea to co-develop a game. The development team were fans of System Shock and sought to create a similar game. Early story ideas were similar to the novella Heart of Darkness. In an early draft, the player was tasked with assassinating an insane commander on a starship. The original title, according to its pitch document, was Junction Point. The philosophy of the design was to continue to develop the concept of a dungeon crawler, like Ultima Underworld: The Stygian Abyss, in a science fiction setting, the basis for System Shock. However, the press mistook System Shock to be closer to a Doom clone which was cited for its poor financial success. With Junction Point, the goal was to add in significant role-playing elements and a persistent storyline as to distance the game from Doom.
The title took 18 months to create with a budget of $1.7 million. It was pitched to several publishers until Electronic Arts—who owned the rights to the System Shock franchise—responded by suggesting the game become a sequel to System Shock. The development team agreed; Electronic Arts became the publisher and story changes were made to incorporate the franchise. The project was allotted one year to be completed and to compensate for the short time frame, the staff began working with Looking Glass Studio's unfinished Dark Engine, the same engine used to create Thief: The Dark Project.
