So, I was doing some more insights on AC3US's strange unlock requirements for the Asterozoa and the Erne, and I noticed something quite interesting.

At first I was confused about the "8 A rank, 16 A rank" requirements, because I've actually unlocked the Erne without obtaining 16 A ranks total.

And then I checked the Records page.

And that's when it hit me - All this time, the "X number of A-rank" thing doesn't apply to how many you have total; It applies to how many you have in each "sector" of the missions. Notice how the missions in the US Records are "divided"? Like, there are eight or so missions before a "break" in between the next set of missions?

Yeah. What determines the unlock is how many A-ranks you have in each "sector", the first two sectors namely. Eight A-ranks in the first sector unlocks the Asterozoa, and I can assume a certain number of A-ranks in the second sector will unlock the Erne.

AC3US is a... fascinating beast.
