In standard steam half life 1, it seems to me that grunts will not engage you or shoot at you until you are within a certain distance of them. Even if they are looking right at you, if you are far enough away they don't appear to do anything for me.
Is this normal behaviour? Is there any way to make them engage you at a longer distance with the default tools and entities?
It seems like in the Dam level in HL 1, there is a grunt on the bridge that will engage you from much farther away that I seem to be experiencing in my custom maps.
Thoughts?
