Stealth How hearing, sight, alertness, memory, group reactions, and target selection combine when enemies notice a Helldiver.
Detection & AI · Major Sight How enemy vision changes with direction, distance, stance, stealth armour, sensor type, and line of sight.
Detection & AI · Major Hearing & sound How far footsteps, weapons, impacts, and other sounds travel, which enemies hear farther, and what suppressors actually reduce.
Detection & AI · Major Alertness & target selection How enemies stay alert, relay reactions, remember possible targets, choose who to attack, and respond after losing sight.
Detection & AI · Major Danger & suppression How projectile near misses build Danger, how accumulated Danger feeds AI behavior, and why aim flinch is a separate target-specific response.
Detection & AI · Major Hive Lord logic How player-slot priority and available underground routes determine which Helldiver a Hive Lord approaches and where it can emerge.
Detection & AI · Investigation Patrols How several Patrol timers run at once, what speeds them up, and how the game chooses a group, direction, route, and spawn location.
Spawns & encounters · Major Encounter timing Why ordinary reinforcement timing changes during a mission, and how objective encounters, scripted waves, and Patrols use separate timing systems.
Spawns & encounters · Major Weapon recoil How drift, camera climb, stance, movement, recovery, injuries, exertion, charge, heat, point shooting, and camera shake shape firing recoil.
Combat & damage · Major Damage resolution How armor and penetration resolve, how periodic damage carries fractional values between ticks, and when projectiles continue through a target.
Combat & damage · Major Projectile damage falloff How retained projectile speed changes direct damage, why distance is only an indirect factor, and how movement, armor, durability, and pass-through interact with falloff.
Combat & damage · Major Explosion falloff & demolition How explosion distance changes damage, Demolition Force, armor penetration, stagger, push, and status strength, including the separate standard and wide-blast curves.
Combat & damage · Major Explosions & line of sight How one explosion can damage several body parts, how each part contributes to main health, and when blast damage requires line-of-sight verification.
Combat & damage · Major Enemy constellations & composition Interactive composition-tag odds, spawn-template composition, and specialist replacements across Patrols, guard forces, Encounters, and traveling groups.
Spawns & encounters · Major Optional objective generation How the selected mission setup, difficulty, map conditions, and weighted selection determine which tactical objectives can appear, including LiDAR Station.
World & generation · Investigation 7.1.0 mission-generation changes Mission-profile and mission-data changes introduced in game version 7.1.0, including Hive World objectives, faction objective pools, and Horde Defend.
