***Under Construction****

So I'm going to mingle the chapter completion achievements and the story based 'obtain this' or 'do that for the first time' achievements here in what was my and will be your approx order of unlocking. This is all pretty much unmissable except one (so I'm not going to type out 'this is unmissable 44 times) which I'll call attention to and you won't really have to go out of your way to unlock anything in this section, just play the game.
