One volunteer who worked on Operation Lovecraft as a translator complained on the Steam forum, 'the biggest issue with this project is the numerous times they have 'rebuilt' the game. Characters still sometimes clip through their clothes or the overactive breast physics go wild, but it's a rare adult game that looks like a big-budget release. It's a long way from the average match-3 puzzle game with stolen art, and boasts of VR compatibility. In addition to customization sliders for hair color and breast jiggle intensity there's one for skin wetness that applies a sheen of sweat to collarbones and other places it might naturally pool. Patreon updates boast of 'Physics based real time body fluid simulation' and 'Dynamic Sweat'.
It's being made in Unreal Engine 5 after beginning in UE4, and has real-time hair rendering and mocapped models. What's made elevated this above Steam's upcoming sex games? While the majority of Steam's flood of hentai games are 2D or static or pre-rendered, Operation Lovecraft is 3D, professionally animated, and interactive.
Over on Patreon, where developer Project Helius is raising funding for Operation Lovecraft: Fallen Doll, it's got almost 15,000 patrons and is the fourth most-popular adult game.
