About Symbiont
Symbiont is a 2D animated adult game built in HTML by VGS STUDIOS, blending horror, romance, and sci-fi. You play as a symbiote hidden in a therapist's office, where Dr. Aris Thorne is meeting Lena Petrova, a corporate analyst. The two believe they are alone, but your task is to move through unseen areas of the room and integrate with both of them. After bonding, your biology changes their emotional responses and pheromonal triggers, pushing them toward intense attraction.
The current build is a demo, so development is ongoing rather than complete. Version v0.2 launched on October 18, 2025, and its changelog marks the initial demo release. It runs on Windows, Linux, and Mac, uses English, and is fully uncensored.
Developer's description
It's a game where you are the monster, but not in the way you might think. The setting for the demo is simple: a therapist's office. Inside, Dr. Aris Thorne is conducting a session with his patient, a corporate analyst named Lena Petrova. They believe they are alone, but the room is infested. Infested with what? You. Your goal is simple, yet intimate. You are a unique strain of symbiote. Direct contact isn't enough; you must achieve full biological integration. Navigate the unseen pathways of the room to get inside both of them. Once you've successfully bonded with both hosts, your unique biology will begin to alter their own, rewriting pheromonal triggers and emotional responses until they become extraordinarily, irresistibly attracted to each other.
