We gave them the ability to hear things, so there will be fewer situations where he’s standing around doing nothing. He was previously unable to react to sounds. His prioritisation for targets should now be much improved. The alien grunt will now make far fewer switches between targets. Instead of immediately dropping to “patrol” state when the alien grunt’s active target is lost, the alien grunt will now attempt to establish line of sight with its lost target.

Instead of going straight from “combat” to “idle”, the alien grunt will now drop into the “patrol” state, where he cautiously walks around the combat area, looking for a target. Previously, when leaving the “combat” state, the alien grunt would drop straight back to “idle”. This should prevent them rushing one by one and make them appear more coordinated.

Made sure multiple alien grunts can advance at once, if they belong to the same squad.Overall these fixes should significantly improve their intelligence, and mostly prevent moments where they behave weirdly or inexplicably. We made a significant number of tweaks and fixes to the alien grunt AI.
