Ectolibrium is a niche and culty science fiction 2.5D platformer. The game is rich with lore, but low on exposition. Its controls are simple but nuanced, letting players become the Outlier, an alien creature hauled from another dimension and discarded into a dangerous wasteland.
As the Outlier, leap and cling to surfaces. Harness alien ectoplasm to fly through the air. Collect nutrient to sprout alien seeds and solve puzzles. Explore cavernous environments in a fallen world of corporate cults, mad science and lost souls, where alien creatures slither through the ruins of a failed utopia, and the engineered slaves of the past toil ceaselessly to siphon ectoplasm from other dimensions.
