CASUALTY PSYCHOLOGY

Mental State, Trauma, Panic Attacks & Somatics for Casualties Unknown

Casualty Psychology is a Cas:U mod that expands the mental state tracking of your expie in Casualties Unknown. It ties mood, fear, physical trauma, and environmental stress into somatic reactions like tremors, panic attacks, sleep disturbances, sensory overload, and over a thousand contextual dialogue lines. This mod primarily adds a contextual tip to WoundView's mood icon and moodles to show information.

    What This Mod Adds

    1. The Six Psychological Pillars

    Your expie's mental state is tracked across six pillars from -100 to +100:

    • []Valence: Emotional state from negative to positive. Tied directly to vanilla happiness. Drained by pain, hunger, sickness, and isolation. Restored by warmth, food, and safe shelter.[/]

      []Arousal: Stress and adrenaline level. High arousal increases pulse, tremors, and panic chance. Low arousal causes lethargy or freezing.[/]

      []Agency: Feeling in control of one's body and situation. Drops when trapped or missing limbs. Recovers when crafting, bandaging wounds, or using tools.[/]

      []Predictability: Situational awareness. Drains in pitch darkness, blindness, or sudden loud noises. Recovers near steady light sources or companions.[/]

      []Social Connectedness: Companionship vs isolation. Rises near living teammates or friendly traders; drains during prolonged isolation in caves.[/]

      []Goal Satisfaction: Survival progress. Kept steady by eating, drinking clean water, dressing wounds, and reaching deeper sectors.[/]

    Expies generate randomized personality traits (Resilience, Neuroticism, Impulsivity, Aggression, Attachment, Masochism, Stoicism, Cynicism, Nihilism) that govern starting baselines, trauma recovery speed, and fear thresholds.

    2. Panic Attacks

    High adrenaline combined with low valence and disorientation can trigger a panic attack:

    • []Tier 1 (Mild): Elevated heart rate and slight reticle tremors. Movement speed and eating are unaffected.[/]

      []Tier 2 (Moderate): Noticeable body and weapon sway, plus a 15% movement speed penalty. Survivors refuse food and drink until calmed.[/]

      []Tier 3 (Severe): Heavy tremors and a 25% movement speed penalty. Temporarily blocks crafting, reading notes, sitting, and sleeping. Extreme stress can trigger vomiting.[/]

      3. Stress Analgesia & Pain Storms

      Major physical trauma triggers short-term adrenaline reactions:

      • []Stress-Induced Analgesia: High-intensity injuries temporarily numb pain perception for 4 to 28 seconds. This gives survivors a window to bandage bleeds or take medicine before pain registers.[/]

        []Pain Storms: When adrenaline numbness expires, unmanaged pain hits all at once. Untreated wounds cause sudden valence drops, arousal spikes, and vocal groaning.[/]

        []Fracture Limping: Walking on an unsplinted fractured leg forces a limp, periodic groans, and an agency penalty.[/]

        4. Sleep, Unconsciousness & Nightmares

        Rest and unconsciousness are tied directly to
