The Underworld: A Transformation Game

An adults-only text adventure where you’re forcefully transformed into a variety of female anthro/furry/monstergirl forms!

Just yesterday, you were a human male living in a modern town. Now you’ve found yourself trapped in The Underworld and your body is nothing like it used to be. Who is behind these changes, and how will you change back? The longer you’re down here, the more you start to enjoy your new life…

This is a transformation text adventure with a rich story — it’s already longer than a novel, and continues to develop. You’ll meet a wide cast of characters across the three factions that each have their own ideology about how to deal with people different from themselves. Your actions will determine which faction achieves victory, and by extension, the fate of humans and hybrids alike.
