The Eternal Cylinder is an action-adventure that puts you in charge of a herd of endearing creatures called Trebhums as they explore a strange alien world. This ecosystem teems with exotic lifeforms and surreal environments, but it's overshadowed by a constant menace: the Cylinder, a gargantuan rolling structure of ancient origin that crushes everything in its path. Real-time world destruction, animal AI, and organic exploration and puzzle design all combine to make survival feel unpredictable and tense.
Your Trebhums start at the very bottom of the food chain, but they can mutate and evolve by eating the flora and fauna around them. Dozens of mutations are available to discover and adapt, including traversal skills like flying and swimming that open up new areas, along with new senses that help you overcome puzzles and dangers. Because each Trebhum can carry different mutations, you're free to build a genuinely unique herd, and every mutation alters a creature's appearance, so stacking them produces surprising new designs.
Beyond the moment-to-moment adaptation, the game offers a gorgeous world full of unforgettable vistas and unique landscapes, with something new hidden around every corner. Ancient mysteries wait to be uncovered as you explore, giving this PC adventure a sense of discovery that runs alongside its constant, rolling threat.
