Drowned City is a third-person non-combat game where you explore a mysterious sunken metropolis, discovering the desolate beauty in its vast outdoor environments. You take on the role of Migu, a young girl with her injured brother, arriving at the city in their small fishing boat. Explore the Drowned City using your boat, climb onto sunken buildings, use your telescope to get a clear view of the city, and find supplies that could help save her brother. As you explore the city at your own pace, you encounter diverse, thriving habitats while uncovering hidden items that gradually piece together the story of a shattered world and a fractured family.
