Alot of guards and a large amount of blinking as well, if you went chaotic.
Everything is marker based except for these key more difficult points.
The Drainage pipe, that is the marker, to get to the lighthouse. Just go to that marker then turn the valve jump down and go inside.
Once you make it to the marker that will bring you inside the actually lighthouse, it will be locked. Although without the key, you can get inside from above the room itself.
Once inside make your way to emily and havelock. Get ready for the ending which is good.
! THE END !
