Underwater/Transport Passageway ①, known as "Lake bottom transportation passage ①" (湖底・運搬通路① Kotei unpan tsūro① ) in the original script, is an area of the Third Energy Facility.
This is the first part of the Underwater Passage, before arriving at the Cooling Water Circulation Chamber. There's a shutter open halfway across the passage with the waterweeds grown on it, which caused it to malfunction.
Upon entry, the player is advised to stay alert because the Mosasaurus can appear and attack from anywhere. Be sure to boost over the obstacle ahead.
