Exilium is an adult NSFW strategy game from Nocturnal Illusions, built in Ren'Py with AI-assisted 2D CG visuals. It mixes worker placement and base building with survival on the foreboding alien world of Gliese-581D. You play the male commander of a colonization ship, manage resources, improve the base, and assign tasks to survivors. Your choices affect whether the colony endures and grows amid mystery and danger, with sci-fi, horror, and pregnancy themes.
The current build is v0.2.6, released on October 9, 2025, and development remains ongoing. It supports Windows, Linux, Mac, and Android, is in English, and is uncensored. This update adds two new races: the Nysari Matronate, an unsettling bio-engineered alien faction centered on pregnancy, and the Solari Order, a radiant armored religious faction focused on purity and discipline. It also introduces six new combat units with unique abilities across multiple factions. CPU factions now react more dynamically, may declare war over player behavior or events, and use improved logic for attacks, trade, and diplomacy. A bug affecting planetary discovery travel was also fixed.
