System Shock - Gameplay

Gameplay

System Shock takes place from a first-person perspective in a three-dimensional (3D) graphical environment. The game is set inside a large, multi-level space station, in which players explore, combat enemies and solve puzzles. Progress is largely non-linear and the game is designed to allow for emergent gameplay. As in Ultima Underworld, the player uses a freely movable mouse cursor to aim weapons, to interact with objects and to manipulate the heads-up display (HUD) interface. View and posture controls on the HUD allow the player to lean left or right, look up or down, crouch, and crawl. Practical uses for these actions include taking cover, retrieving items from beneath the player character and navigating small passages, respectively. The HUD also features three "Multi-Function Displays", which may be configured to display information such as weapon readouts, an automap and an inventory.

The player advances the plot by acquiring log discs and e-mails: the game contains no non-player characters with which to converse. Throughout the game, an evil artificial intelligence called SHODAN hinders the player's progress with traps and blocked pathways. Specific computer terminals allow the player to temporarily enter Cyberspace; inside, the player moves weightlessly through a wire frame 3D environment, while collecting data and fighting SHODAN's security programs. Actions in Cyberspace sometimes cause events in the game's physical world; for example, certain locked doors may only be opened in Cyberspace. Outside of Cyberspace, the player uses the game's sixteen weapons, of which a maximum of seven may be carried at one time, to combat robots, cyborgs and mutants controlled by SHODAN. Projectile weapons often have selectable ammunition types with varying effects; for example, the "dart pistol" may fire either explosive needles or tranquilizers. Energy weapons and several types of explosives may also be found, with the latter ranging from percussion grenades to land mines and adjustable time bombs.

Along with weapons, the player collects items, such as first-aid kits and dermal patches, during the game. Dermal patches provide the character with beneficial effects—such as regeneration or increased melee attack power—but can cause detrimental side-effects, such as fatigue and distorted color perception. Attachable "hardware" may also be found, including energy shields and head-mounted lanterns. Increasingly advanced versions of this hardware may be obtained as the game progresses. When activated, most hardware drains from a main energy reserve, which necessitates economization. Certain hardware displays the effectiveness of attacks when active, with messages such as "Normal damage". When an enemy is attacked, the damage is calculated by armor absorption, vulnerabilities, critical hits and a degree of randomness. Weapons and munitions deal specific kinds of damage, and certain enemies are immune, or more vulnerable, to particular types. For example, electromagnetic pulse weapons heavily damage robots, but do not affect mutants. Conversely, gas grenades are effective against mutants, but do not damage robots.
