Damn, you're right... How could I have missed that for an hour...Originally Posted by AngryRaisin Go to original post
I had taken that tunnel 100 times already, but somehow completely missed the opening above...
Doh...
If it helps, the underwater entrance is under where you find the red explosives barrel. Or using the picture above as a reference, he should turn to the right, go left around the corner, straight back to the corner (to where the other door is located) and then a little bit more right. Below that. The underwater path is kind of long, but as I recall, was a series of left turns until it is time to go up.
Their must be opening around the deck. The door which is made of brazil white wood, completely wet. Their must be hole in the room. Something problem so you are facing this problem. But for some reason when viewing the map while in there it says "Charlotte" so everyone calls it Charlotte. I'm putting this post here for future people searching.
