Where is the underwater door in Garrison?
I am trying to find the underwater door where to destroy the temple powersystem in order to open the doors to the temple. I dont know is my copy of Marathon 2 faulty or what, but no door is found neither in 'grotto' nor in the pool adjacent to it.
That door is not actually underwater. When you emerge from the underwater tunnel and come into the pool, there is an opening to the north that leads into the main water area. Standing in that opening, you can see a trooper on a ledge just to your left. The door is behind him.
There is also a secret door at the end of the hallway just east of the temple area that has a switch that will open the temple doors.

Look out - he's nuts!
