Some mods will give you things like trophies or meat when you kill them and cut them with the knife, but in the base game you never really were supposed to fight them. They were just hazards to avoid or run from.
I think it would be unique if you could get bones or hide from certain aliens. I sort of imagine hide being for crafting diving suits that give you additional abilities. Bones on the other hand would be useful for making weapons or mods for vehicles (sort of like Marguerit‘s prawn suit).
I think that’s a really cool idea. Maybe, killing them doesn’t reward you with anything, but you can rarely find a dead one, and you could get materials from it.
