Shellbound is a hand-drawn 2D Metroidvania where life can only exist on a gigantic snail. Explore a vibrant world, fight bizarre flora and fauna and discover civilizations fueled by the powerful snail mucus. It is the key to your natural role: Devour everything so life itself continues to exist.

Discover a literally living world

Shellbound is set in a barren world where life can only emerge from the fertile mucus of a gigantic snail. You are a parasite, born from the almost dried-up mucus trail it leaves behind and plunged into the bottom of the food chain.

Follow the trail towards the colossal creature and enter a vibrant, dangerous ecosystem. Explore dense forests, cities of copper, mucus mines and many more regions on the snail's body and inside of its winding shell.

Soon, you learn that the creature has started moving again after a millennia-long slumber – but nobody knows why and where it is heading. Uncovering this mystery will reveal not only the bizarre life cycle of the creature but also your natural role in this world.

Explore a Superorganism

Control your Enemies

Evolution on Steroids
