Player Mechanics
In Expeditions dawn/night the servo skull will only fire at targets within 12m or so of the player, if you target an enemy outside that range it will just stare at it menacingly. And consume capacitance through Noosphere.
-Walk around in Expeditions on a mission with dawn or night modifiers
-Servo skull only shoots close range targets and tags
Power Supply Interruption (Lights Out / Night darkness): Max range capped at 10 meters
Ventilation Purge (Heavy fog): Max range capped at 24 meters
Smoke Grenade smoke clouds block Servo-Skulls from firing at enemies entirely.
And psyker dome / the dome shield crate you can buy in expedition nullifie the shots. Veteran smoke grenade impacts it too
I suspect Fatshark directly reused the enemy gunner’s code for the servo-skull. This causes it to be affected by many of the same factors that influence enemies, preventing it from functioning properly. For example, smoke grenades can block its targeting, and during power outage missions, its effective range is drastically reduced to just 10 meters. This matches the behavior of enemy gunners under the same conditions.
