Is there a save where the maximum is open ? What is possible?Can not have everything open because in the first office visit you will miss at least 1 option but most of the time you will miss 2 options.
That is in one playthrough, will take at least 2 maybe 3 playthroughs to see everything the game has to offer for chapter 3.
Maybe later dev will put the same option that we had for the Island in chapter 1 but will have to wait and see.
