Lost Harem is an adult game built in Unreal Engine by Nonahki. It plays as an adventure with 3D CG visuals, set in a dystopian world. You play a man searching for his harem, while desire pushes you forward without hesitation. The tone stresses urgency, attraction, and pursuit. The goal is clear.
The current build is v24.06, released on June 25, 2021 for Windows, with English plus five other languages and no censorship. Development appears ongoing, since this update added a first-person camera for certain intimate poses, a Strip Club location where girls can serve you, a new achievement, and a map with search logs placed on a bench near the main house. Earlier updates also added languages, gameplay fixes, interaction changes, and hints.
