Detection & enemy AI
How enemies sense players, become alert, share information, and turn perception into behaviour.

Mechanics in Helldivers 2 do not fit cleanly into isolated folders. OTL uses a simple hierarchy for browsing, then preserves cross-system relationships so a subject such as Stealth or Constellations can point to every mechanic it affects.
StealthThe cross-cutting layer that connects enemy perception, alertness, information sharing, and behaviour after detection.
Detection & AISightVisual detection rules, sight multipliers, visibility checks, and the conditions that let an enemy see a player.
Detection & AIHearing & soundHow sound is produced, scaled, perceived, and converted into enemy investigation or alert responses.
Detection & AIAlertnessEnemy awareness states, escalation, shared alert information, and the bridge between sensing something and acting on it.
Detection & AIEnemy AI behaviourThe decisions enemies make after perception and alert state are resolved, including investigation, targeting, and combat behaviour.
Detection & AIPatrol compositionWhich enemy packages can be selected for patrols and how world-state inputs can change the available composition.
Spawns & encountersPatrol timersThe authored and runtime timing rules that control patrol creation cadence and how those timers can be modified.
Spawns & encountersPatrol lanesWhere patrols are permitted to travel and how generated mission space constrains their routes.
Spawns & encountersEncounter compositionHow encounter packages are selected and how faction, world state, mission generation, and enemy tags affect the result.
Spawns & encountersHow weapon damage is resolvedNormal and durable damage, hit-zone durability, armor, impact-angle penetration lanes, and the damage evaluation pipeline.
Combat & damageExplosions & line of sightExplosion radii, obstruction checks, body-part interactions, and how explosive damage reaches parts and main health pools.
Combat & damageEnemyTags & constellationsHow broad EnemyTag rolls, special overlays, squad candidates, concrete variants, and deterministic replacements shape enemy composition.
Spawns & encountersPlanetary clocks & day/nightResearch into the celestial hierarchy and transforms used by planetary clock and day/night behaviour. This is separate from EnemyTag constellations.
World & generationMission map generationHow a mission seed becomes terrain, objectives, extraction, encounter space, and other generated battlefield structure.
World & generationVehicle impacts & demolition forceHow moving vehicles turn collision state into damage and demolition effects against enemies and destructible world objects.

Systems are the stable top level. Mechanics sit beneath them. A mechanic can still connect to any other system through the relationship map below.

What appears on the map, what can appear in patrols and encounters, where those groups travel, and when they are created.
