System Shock

System Shock is a first-person shooter with puzzle-solving and light role-playing elements. The gameplay incorporates gradual exploration of the Citadel's ten levels, interaction with the environment, problem-solving, fulfilling objectives, and combat.

On his way the hacker encounters numerous enemies - robots, cyborgs and mutants, all of which can be fought back with a variety of weapons. Some of the weapons use ammo, while other have infinite ammo and instead draw on electric energy. Some weapons are more effective on certain foes - e.g. the dart gun only works on organic enemies, while the magpulse is best used against robots. Once killed, the enemies can be searched for ammo and other items. The player can also find items in crates, cabinets, corpses or just lying around on the ground.

Apart from weapons and ammo, the player can find patches (such as medical patches, which replenish the hero's health; berserk patches, which temporarily increase his strength but cause hallucinations; detox patches, which remove the harmful effects of radiation and biohazard; etc.), grenades of various kinds (EMP grenades are effective against robots, gas grenades are good for mutants, land mines can be used to set traps, etc.), battery packs for replenishing electricity, first aid kits for restoring health, and others.
