So this is a topic in regards with lore, we have here three different types of npc relationships:

Xen wildlife.
Nihilanth's army.
and combine.

But in this mod bullsquid, houndeye or panthereye join nihilanth's army which is not supposed to be that way, they are enemies ( headcrab has it's own faction at least ) and all other species that live in xen should hunt each other like in half life 1. We witnessed bullsquids hitting alien grunts or aliens slaves, vortigaunts or whatever you wanna call it.
With the exception of bullsquid and the houndeye species these live in peace and harmony between them.

One side of the fans think also that the combines enslaved Nihilanth's army before and during hl1 and those entities are: alien slave, alien controllers, alien grunts and the non-canonical ones, tor, control sphere, etc... and I am one of those fans. this puts them in combine's faction.

how do you think teams should be?
i'd like to request an internal change between npc relationships, not the tool that only allows change one npc at a time and have to set everytime I reset the game repeatedly.
