Q:
Where is the navigation orb?
A:
In the hut next to the lighthouse, there is a secret room on the second floor with the navigation orb
inside. You open it in the attic with a switch located near a crack in the floor.
Q:
Where can I find the key to storage room #5?
A:
The key to storage room #5 is in the sub-aquatic station #1. This station has a room
with a lever that opens the entrance to this station. Look there for a hole in the floor
where you can access the basement. In the basement, you will encounter several rooms
where the water is a few feet high; in the last room, the key lies on the floor. (under water!)
The key is of orange-golden colour, so you can't miss it.
