STEALTH SYSTEMS

Detection infrastructure that escalates a stealth situation when triggered — cameras, tripwires, guards reaching a phone or panic button — shifting the level from its quiet state into reinforcements, lockdowns, or search behavior.

Enemies progress through discrete awareness levels — unaware, suspicious, searching, full combat — and behavior escalates at each stage.

Unconscious or dead bodies persist as evidence that other characters can discover, forcing stealth players to manage the aftermath of takedowns — dragging corpses to closets, dumpsters, tall grass, or off ledges.

A visible gauge showing how close an enemy is to noticing the player — filling as you linger in sightlines, draining as you break contact — with thresholds for suspicion, search, and full alert.

The player dons enemy or civilian clothing to move through restricted areas without triggering hostility, trading stealth-by-shadow for stealth-by-blending-in.

Throwable or deployable objects that manipulate enemy attention — a bottle tossed to pull a guard off his route, a noisemaker arrow, a whistle from cover.

Audio cues tied to movement that change based on surface material and speed, serving as both an immersive detail and a functional gameplay signal for stealth.

Players bypass or take control of electronic systems — cameras, turrets, doors, terminals — through a dedicated minigame or ability, opening alternate routes and tactical options.

Illumination as a stealth variable — visibility to enemies determined by whether the player stands in light or darkness, with shadows as safe zones and light sources as tactical objects.

A minigame or skill check required to open locked containers or doors without a key, usually risking a broken pick or alerted guards on failure.

Bait that draws enemies to a chosen location — thrown meat for beasts, planted pheromones, deployed decoys, whistling from a bush.

Player actions producing sound that AI hears — footsteps on gravel, gunshots ringing across the map, a knocked-over bottle — making audio a stealth dimension parallel to sight.

Guards and enemies follow predictable paths through a level, creating windows and rhythms the player learns and exploits.

Areas where the player's presence is itself the violation — trespass zones triggering hostility or suspicion, no-go military perimeters, disguise-gated backstage areas — making location a stealth condition independent of behavior.

Automated surveillance as stealth obstacle and player tool — wall-mounted cameras sweeping arcs that trigger alarms, camera networks the player can hack and ride, CCTV rooms where a guard watches the feeds you're avoiding.

The player eliminates or incapacitates an enemy without raising an alarm — a stealth kill, chokehold, or tranquilizer — clearing a threat while preserving concealment.

Enemy sight is visualized as a cone or field projecting from each guard, making exactly what they can and can't see explicit to the player.
