I think xenos could use an additional status for hive behavior like Hive Orders, it could be called Hive Attitude. (Can't think of a better word right now)
The queen could set it with a predefined list (like pheromones) and every xeno would get a notice in chat and see it in status tab, so like hive orders, but maybe a cute HUD display would be good too.
My recommended attitudes:
Scavenge: typical early game stuff
Skirmish: attack easy targets but dont fight their defences (I'd call this one the most standard attitude)
Defend: only fight in the hive and defended territory
Regroup: pull back and wait for most xenos to show up
Assault: try to destroy enemy defences
Capture: for times when capturing is more important than anything else listed here
Why add this if Hive Orders already exists?
Because this would have a standard meaning, if I put "Skirmish" in hive orders people wont have much idea what I really expect.
Hive orders can be typically used for more nuanced stuff like "Dont let the turtle retreat to their base".
