Shinsekai 4.0.0

Shinsekai Into the Depths is a fresh and thrilling deep-sea adventure game. The land has slowly but steadily been covered with ice, forcing mankind to take refuge in the ocean. Even the sea cannot protect them forever. The ice overtakes the undersea home of a lone aquanaut, forcing an unplanned journey of exploration and discovery.

You must manage your oxygen reserves as you make your way through this magnificent underwater world teeming with life. You need to maintain your suit's pressure resistance as you proceed deeper into the ruins of past civilizations.
