Aquatico

Aquatico is a survival city builder set within the depths of the sea. Strategically build an underwater city atop the ocean floor and face the challenges that accompany an oceanic life.
Build a unique city underwater to escape a dying world. Survive the challenges of the sea and construct your base over multiple levels. Use the seabed to build core infrastructure and production facilities, while the domed layers above will house your people from the dangers of the depths.
