I know Rare said its a medium update but...
I've been searching all the books for a few hours and then i just got the drum, I found more crews to team up with ( another galleon and 2 sloops ) and we killed the megalodon.
It wasn't easy, but we finally killed it.
I dont know if there is something else to play on this new update or if that was all.
I know its a medium update but if killing megalodon was the end of the new content ... I was expecting just a few more, maybe just a larger campaign :/
