Play as Nia, a newly formed ocean spirit

Brought into existence in a sea smothered by pollution and death.

With no life remaining, Nia must restore The Abyss by:

• Destroying trash and clearing oil spills
• Revitalizing the seafloor
• Growing plants
• Helping marine life
• Rebuilding ecosystems

Explore The Abyss

• The Abyss is divided into interconnected ecosystems, each with central hubs surrounded by Outer Zones of pollution.
• Restore each zone, earn the trust of its marine life, and watch them join your home hub, becoming part of a growing ecosystem.
• Solve increasingly complex ecological puzzles that stand between Nia and The Abyss.
