Operation Lovecraft: Fallen Doll

Play as an assistant to Dr. Anya, a Miskatonic University neurobiologist studying encounters of the third kind on Yuggoth, a dwarf planet in the Kuiper Belt. Dr. Anya surgically implanted a cognitive filter in your prefrontal lobe to secure your sanity while experimenting on the eldritch horrors - as it keeps you from going mentally unstable, the cognitive filter also distorts your senses into making experiments look like orgy pornos and tentacle hentai. Nothing particularly bad about that...right?

Operation Lovecraft: Fallen Doll is a Cthulhu mythos inspired sex simulator and third-person sandbox created by a bunch of perverts with AAA game development experience. All graphics are acted out in real time rather than pre-rendered CG, with intuitive player interactivity affecting the shots, movements, and voices in-scene. Third-person desktop and first-person VR versions are available.
