I'm in England(60%).I'm in a dark place with water and sitting on a coffin.(Brrrrr!That's really creepy!) I keep wandering in this place and go through some gates,pulling levers underwater and throwing the grapple to some torches.Then I got totally lost and exitted from the game and I have to do the same route cause there was no checkpoint there.The last checkpoint as much as I remember was a while before I dropped the coffin on the water.Please help me!
after you pull the second lever, turn 180, a coffin comes out, take the coffin to the destructed switch. and jump from the coffin to the destructed switch.
