RESTRICTED ZONES
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.

Hitman built its genre-defining social-stealth on concentric zone permissions (the lobby tolerates everyone, the staff corridor demands a uniform, the target's suite tolerates no one — and every disguise redraws the map), Elder Scrolls and RPG towns flag interiors where entry is crime, MGSV marks hot zones where guards shoot on sight, and open-world games ring endgame areas with restricted perimeters as soft level-gating. Designers use restricted zones because they make space itself carry rules: the same corridor is safe or lethal depending on paperwork, which turns maps into permission diagrams the player learns to read — and in disguise systems, the zone map composes with the costume system into the genre's core puzzle (this outfit unlocks these spaces, that one those; the route is an outfit-sequencing problem). Zones also produce graduated tension mechanically: trespass usually escalates through suspicion before violence, so depth-into-forbidden-territory is a risk dial the player operates by walking. The legibility question is everything: players must know when they're crossing a line, or every alert feels arbitrary. Key decisions: boundary communication (Hitman's UI states, guard barks warning trespassers, architectural language like doors and checkpoints versus invisible lines), enforcement response curve (warn, escort out, attack — instant hostility wastes the tension gradient), and whether permissions are dynamic — disguises, story states, and faction reputation redrawing the zone map is where the mechanic gets deep. Pitfall: invisible borders with lethal enforcement — a zone whose edge the player discovers by dying to it converts spatial rules into trial-and-error memorization; restricted space works when the border is readable before it's crossed, because the mechanic's drama is the decision to cross, not the surprise of having crossed.
