Welcome to Submerged: Hidden Depths. A drowned city, crumbling tips of skyscrapers stubbornly standing above the waves. Deserted villages, now inhabited by enigmatic creatures. And beneath the surging ocean waits an anguished, angry presence. Submerged: Hidden Depths is a non-combat third-person “relaxploration” adventure, set in the sunken ruins of a beautiful world. Take on the role of Miku and Taku – one cursed with a mysterious power that she wants to use for good, the other determined not to let it tear them apart. Boat across tranquil waters and storm-driven white-caps, explore and climb what remains of a once-towering city, and scour the buildings for the seeds of its salvation.
Stage 1 – Play through the Main Story.
Play through the main story campaign by visiting all 10 of the Seeds. Use the world overview map to help you navigate the world to discover and recover all of the collectibles in the game. You should visit all 10 of the Lookouts as soon as possible as these will reveal a lot of items and destinations on your map. Use the telescope frequently by scanning in 360 degrees rotations at a time. Note: Sometimes some collectibles will not reveal themselves unless there are no items blocking the visible distance between you and the desired items you are looking for.
There are a few hundred items to collect in this game. Therefore this video link is provided as one example of where to find all items. Credit for the YouTube video goes to The Welsh Hunter.
Stage 2 – Clean Up.
If you missed any of the collectibles in the game, you can continue to play the game to find all items. Note: Use the Fast Travel at the Seeds to help you quickly navigate the world. Your boat will always be at whatever location you fast travel to. Use the YouTube video above or search for another if you like.
