Symbiosis is an adult 3D adventure created by indica_project using Unreal Engine. In this fantasy setting, you build and manage a symbiote population by capturing organisms and breeding them. The player can take control of infected units, operate tentacles, and explore themes that include fantasy, tentacles, and mind control.
The current build is Demo 6.4, released on September 5, 2024, for Windows. It is presented in English and is uncensored. Development remains ongoing, with additional content expected in later updates. Earlier demo versions introduced an open world map, added nonplayer characters such as an Orc, a Slime, and a horse, improved targeting and swimming, and expanded armor and tentacle slot interface options while fixing bugs. The 6.1 demo also aligned nonplayer characters with the ground, added debug time acceleration, and made visual corrections.
