Etlina's Principle

Etlina's Principle is a 3D adult adventure for players who want body-horror corruption stories with a monster girl slant. It plays calm and grim rather than comedic, with a military-mission backdrop.

Story

Humanity's experiments with a symbiotic organism called Nox Limax went wrong, and people began transforming into slime-like, latex-textured creatures as the world around them turned alien and hostile. As a member of the HOWL Squad, a military unit built for high-risk operations, you're sent into this changed territory, where you'll meet transformed locals who defy the warnings given about them. The choices you make about who to trust will shape both their fate and humanity's.

Gameplay

You move through point-and-click missions and dialogue-driven scenes, gathering information and deciding how to handle the hybrid creatures and survivors you encounter. Choices affect who becomes an ally, who becomes an enemy, and how individual operations resolve. Encounters with monster girls and transformed humans combine exploration with adult scenes tied to the people you side with.
