Oh, that place, um, well If i remember correctly, when you first walk in theres a bunch of those flying cutting thingies, so then you blow up those gas tanks, and you're supposed to like walk up to the railings and jump on the big pipes on the cieling. then you walk over to the next room where you'll see a valve, make you way too that valve and turn it all the way, the room will fill up with water, then go back to the original room that had the gas tanks and swim down in that room, you'll see an opened circle that you can swim into, then you arrive in a new room. This room in order to walk over to the other side (you'll get what i mean) you gotta swim down and shoot the planks so that these round thingies can float up, then you jump across and i can't remember what happens after that.
