Player Threat Level

The "Threat Level" of the player helps Horizon determine how difficult to make certain game mechanics
 * The amount of ammo, meds, cures, food, and water you are currently carrying increases your threat
 * Each type of item increases threat by different amounts
 * Bandages/stims are separated into 3 categories to account for different healing amounts
 * Food/water is separated into 3 categories to account for different meal sizes
 * Ammo is separated into 4 categories to account for different calibers and ammo types
 * This value is done "behind the scenes" and will probably never be shown to the player (so don't ask)
