IDEA
Different alien species which capture each other's nests and the more you destroy the enemy the less likely they are to attack you.
These species also allow you to harness Alien artifacts for them. But this will drain your relation.
The factions will contain etc.. sapient aliens. But it includes the generic units aswell.
And different building types. Or other traits
Example:
RED FACTION (VERY HOSTILE 9)
Red Faction Biter, Red Faction Worms, Red Faction Extreme Spitters (30 Range distance)
BLUE FACTION (HOSTILE 6)
Blue Faction Biter, Blue Faction Worms, Blue Faction roaches (Super fast units)
^^^^^^ ONLY EXAMPLE ^^^^^^
