Buy The Eternal Cylinder PC key

The Eternal Cylinder is about a family of small creatures called Trebhum trying to survive on a dangerous planet and stop an ancient, gargantuan structure known as The Cylinder. You guide the Trebhum through a vast world of strange creatures and environments, using their ability to mutate and adapt to overcome obstacles and escape the destruction left by The Cylinder.

The world and The Cylinder

The open world contains four distinct biomes filled with unusual plants and animals. When The Cylinder roars to life, it crushes the landscape in real time: trees fall and obstruct escape routes, while hills and mountains are flattened, removing places to hide. The Trebhum must run to survive.

The Cylinder also creates servants that infest, destroy and consume the planet’s natural life. These monsters are dangerous, and you need to stay away from them.

Adapt and explore

Each Trebhum can gain mutations from a selection of more than 50. These can let them grow spikes, shoot tornadoes, fly and more, providing different ways to deal with obstacles. Mutations also change a Trebhum’s appearance, giving each herd a varied collection of creatures adapted for survival.

You can seek out hidden sanctuaries built by earlier generations of Trebhum. Their complex puzzles guard ancient knowledge passed down through the generations, and the sanctuaries hold the only hope for the world.

Creatures and mutations

Two additional creatures roam the world: the highly aggressive herbivore Buddugh Gropp, found in tundra biomes, and the large tripodal omnivore Gharukuk, found in the desert. Trebhum can also develop a fiery mutation that lets them shoot jets of flame from their trunks, warning potential predators that they may be too spicy to eat, especially those with fur.
