About Shellbound
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
Explore the ancient snail, a gigantic living organism whose bodily functions massively impact its inhabitants, the world and the gameplay.
Control your Enemies
Control enemies with your parasite skill to get a strategic advantage in combat, overcome obstacles, enter secret areas, solve puzzles and much more
Evolution on Steroids
Fight the ecosystem – but it fights back! Killing too many enemies of one species will let them evolve into a stronger version with new abilities that you can use.
Find new Friends
Befriend NPCs with an interactive friendbook and discover their secrets and quests.
