It seems that this is a very controversial idea, as the poll shows; there's no definite majority of the voters in any particular stance on it.
(That basically means that the poll is half-n-half with no clear-cut majority)
I agree with those here that say it's pointless for small aliens to have these details; they aren't needed simply because there's too small of an HP level for it to be worth the time to code.
I meant for this to be primarily for the larger aliens, mara/goon/rant, and it shouldn't seem too hard to code to me.
Just have individual hitboxes; for the tyrant, put one on the leg area, one on the torso/midsection/tail area, and one on the neck/head area. Same applies for goons and maras.
