Ultagenics - The Parasite

Ultagenics - The Parasite is a text-based visual novel for players who want corruption stories with a sci-fi edge. The tone stays calm and character-focused even as things turn explicit.

Story

In a town where a megacorporation quietly shapes daily life, Christine Marshall works as a therapist who helps people confront desires they've learned to bury. Her methods are unconventional: she carries an engineered alien parasite built to surface and amplify hidden urges, both in herself and in the people she treats. Together they move through Summit Valley, drawing out what the town's residents have spent years suppressing.

Gameplay

Play centers on Christine's sessions and encounters with residents of Summit Valley, told through dialogue and narrated scenes rather than exploration or stat management. Choices shape how she uses the parasite and how far each interaction goes, with the story branching around trust, curiosity, and escalating desire. Progress is tracked through her personal PDA, which surfaces new scenes as relationships with specific characters develop.
