All on the Line - part I | Episode 8 RE: Revelations Guide
Last update: 11 May 2016
When you try to get to the door, the room will be flooded.
Swim forward until you get to place, where you can emerge.
After that head to northeast corner of this location. You find a ladder which takes you to the surface.
As it turns out, the elevator is broken. Jump back to the water where the map shows.
Behind a door under the water, you find a corridor leading to the staircase.
On its top you find a ladder. Climb to the top and look at a door marked with trident. It is locked.
Jump to the water and approach door at the very bottom.
Then you have to head forward, breathing when you can and avoiding swimming monsters. Your target is marked on yellow on the map.
When you enter a canal, go to its other side and dive again.
Behind one open door swim forward until you see a narrow passage in a broken window.
It takes you to further corridors, at end of which you find a big flooded room.
Emerge on the surface and go on the land where you can see black-yellow stripes.
Then go further to the shaft, from which a broken ladder hangs. Tunnel leads to the casino, where this part of episode ends.
