- Closed Beta Update 0.9.0 - 28 August 2026
Thank you for your patience! This update marks the final Operation: Lovecraft update mainly focused on adding a new investigator. Over the past months we attempted to develop the new Research Pass at the same time as iterating on Campaign Mode; this approach has proven to prolong both development cycles, resulting in release delays. As compensation, we’ve distributed Gift Boxes to all players - please check your in-game mailbox in the Closed Beta to claim them. This update’s highlight is the new investigator, ADA. ADA (Administrative Digital Assistant) serves as the Pioneer Council’s Minister of the Secretariat. A cyberdoll with many years of experience in Earth’s civil service, she has mastered not only its regulations and procedures, but also the subtle art of steering a vast bureaucratic machine in service of the Council’s will. Additionally, we’ve redesigned the game’s official webs…
- Closed Beta Update 0.8.9 - 16 January 2026
The next community-voted investigator, Yanshi the Inventor, has joined the crew!Yanshi was initially designed as an application-level AI specialized in mechanical design. After successfully completing numerous automated design projects, Yinglong Industries transferred her into a cyberdoll body to enable her to collect data and engage in self-learning in the real world as needed. However, as she was not originally developed as a general artificial intelligence, the emotional module installed in her does not synchronize properly with the motor system of her bionic body, making her speech and movements appear somewhat rigid and wooden. Though her expressions remain consistently blank and her speech lacks intonation, Yanshi does not lack emotions — she simply struggles to express them. She remains, at her core, the shy girl from the laboratory.Version 0.8.9 marks the final test release sole…
- CLOSED BETA UPDATE 0.8.8f - 12 August 2025
We have pushed update 0.8.8f on Steam, addressing most performance/graphic issues reported in the previous builds. We will change the Experiment list UI back to scroll bar and implement animation fixes in the next patch. FSR now works with AMD cards Improved network connection stability GPU usage and memory overhead are greatly reduced Framerate glitch in Neo Dunwich fixed Galatea's voice and facial expression bugs fixed Fixed low-poly geometries in the maps No more blurry textures (unless your GPU memory is lower than 6GB) Lighting and shadow are now working as intended
- Closed Beta Update 0.8.8 - 1 August 2025
Greetings, Researchers! The Steam closed beta branch has updated to version 0.8.8, with a new investigator Detective Galatea joining the squad. Starting with Galatea, we will strive to release a new investigator every 4 months, with the full content breadth for each new investigator releasing in two updates spaced 2 months apart. Each update will include 24 sex scenes. When the second update for each investigator releases, the rate of obtaining additional experiments will increase, which should address previous concerns where new scenes for previously released investigators were difficult to obtain through Blueprint analysis. Between those updates, we will update monthly to optimize already implemented sex scenes. If you encounter any bugs, please submit a bug report on the project’s Github page. Thank you for the support! Additions: New Investigator: Galatea 24 Galatea experiments adde…
- CLOSED BETA 0.8.6 PATCH NOTES - 2 January 2025
Happy New Year! A new investigator joins the squad in this Closed Beta update. https://iili.io/2Seh8UQ.gif A century ago, the Lunar War erupted over the contested Lagh Metal meteorite that had fallen on the Moon. During the conflict, TALON (Tactical Aviation Low Orbit Network) commanded over a thousand air battles. The deep neural network formed by intercommunicating orbital fighter squadrons quickly surpassed human tactical ingenuity, demonstrating foresight far beyond even the greatest strategists. After the war, TALON was decommissioned and repurposed as the navigational AI for the Archimedes, guiding the spacecraft unscathed through the dense asteroid fields of the Kuiper Belt to ultimately reach Yuggoth. Outwardly carefree and nonchalant, this veteran pilot has been quietly longing for the day it might once again soar freely in the skies like a bird—and perhaps that day is closer t…
- Update 0.8.5: VR and Lounge Mode - 20 October 2024
It’s been a long time coming! Update 0.8.5 has finished testing and is now available for download through the closed beta test branch. If you encounter any issues, please feel free to file a bug report through our Github! This version adds VR support, accessible via the OpenXR option when launching the game. Also added this update is Lounge Mode. Lounge Mode will contain several differently themed maps, from Neo Arkham’s subway to a spa resort in Neo Ipswich. It is completely single-player, and other players cannot join your room. The first Lounge mode map can be accessed via selecting Crew Quarters in Archimedes Station. You may also move between the crew quarters and main deck of Archimedes station directly in the map: the blast door in the crew quarters leads to the main deck, and the elevator in the main deck leads to the crew quarters. In this update we added 8 new sex scenes: No.1…
- One Million Wishlists Achieved! Closed Beta Access Giveaway - 20 April 2024
Operation Lovecraft has achieved one million wishlists on Steam!🎉 As an adult-only project with zero marketing budget this is miraculous to us. Seeing an 18+ restricted game amongst recognizable masterpieces in the top wishlisted list feels kind of unreal. Due to our decision to not release a half-finished game on Steam through Early Access but instead to officially release when it is satisfactorily completed, the development progress has been hazy to many folks who have been following us. We’ve recently upgraded Operation Lovecraft to Unreal Engine 5 and added controller support. The VR version of Harem Mode will be added in the upcoming 0.8.5 release. Update 0.9.0 will introduce core gameplay aspects with the combat system, and will be the last major update before official release. We’re pushing hard to improve & polish the game as quickly as possible, and we’d like to thank everyone…
- CLOSED BETA 0.8.2d PATCH NOTES - 18 April 2024
Greetings, Researchers! We’re hosting our first screenshot contest over on our Discord server, and invite everyone to submit screenshots to enter. The top 10 will receive prizes such as Neo England Pounds in Harem Mode, and voters will have a chance to earn extra Likes. Closed Beta Patch 0.8.2 includes the largest update to Harem Mode since its refactoring. We upgraded the game engine to Unreal Engine 5, removed the Sanity system, and added new investigator Juzi with 52 accompanying sex scenes. Juzi is the elder sister of the AI twins embedded in the deep space transport ship Zhenghe, responsible for the colony's construction and architecture design. The Zhenghe, en route to Yuggoth from Titan, will be converted into the new synchronous orbital command center to succeed the Archimedes Station after it enters planetary orbit. Contrary to her quiet, more temperamental sister Yanshi, Juzi…

Bug Fixes: Fixed an issue where some sound effects were not affected by volume settings. Fixed issues with certain poses in cumflated state. Fixed various clothing clipping issues.

RAM usage decreased by 50%. Settings and outfit customization UI improvements. Adjusted the maximum duration of c…
- CLOSED BETA UPDATE 0.7.75b - 28 November 2023
With Update 0.7.75, frame rates should double on average for most players. We will later add a FPS cap slider to the game via hotpatch so your machine doesn't roar like a jet engine. If you ever had or have issues accessing Harem Mode due to hardware limits, give it another go. CHANGELIST: 12 new sex scenes for Celia, Alet and Erika. 4 additional scenes for Dr. Anya will be added in update 0.8.0 along with Research Pass: Juzi. Female characters now use different voices and sucking sounds when blowing different sized penises. Fixed all gallery related issues and added squirt VFX. Female characters will now use suffocation voices and facial expressions in choking sex scenes. Improved the highlights of Elizabeth’s hair. Reworked Elizabeth and Celia locomotion animations and fixed the breast deformation issues with Elizabeth and Anya's environment interaction, masturbation and operation bed…
- Closed Beta Branch Update 0.7.5 - 28 September 2023
Greetings, Researchers! Update 0.7.5 brings a new investigator: Elizabeth Carter, with 53 new sex scenes. Elizabeth Carter has been at the helm of DMAIC for nearly two hundred years, but this iron-fisted technology oligarch shows no physical signs of aging. The official explanation from DMAIC is that Elizabeth has undergone extensive gene therapy to achieve immortality, yet her longevity still spawned many a conspiracy theory: Some believe that she is a periodically replaced clone with Elizabeth’s memory while more radical ones claim that the Carter family has a long history of cutting deals with aliens. New experiment subjects: Gug and Tcho-Tcho. After this update, all investigator blueprints can be obtained and analyzed normally even if you do not have their respective Advanced Research Pass. Green and Blue experiment synthesis costs have increased, and you will still require the asso…
- Closed Beta Phase 2 Started - 5 March 2023
Greetings everyone, it’s been a long journey. Rebuilding the entire project for better performance was not an easy choice, with a lot of work needing to be redone from scratch. We understand your anxiety and concerns - through the past months, all hands of the development team have been on deck to get the rebuilding done as we are no less eager than you. Version 0.7.0 will be the first stable rebuild release, with the closed beta currently open to crowdfunding supporters only. Please note that due to time constraints we have not been able to finish internal testing and there is bound to be plenty of issues and bugs. If you do encounter said issues, feel free to submit a bug report through the #bug-report channel in our Discord server. Some features that were not properly tested have been temporarily removed in this build (the test has already been delayed twice so we'd rather cut some c…
- Steam's most-wanted sex game is trapped in development hell - 23 February 2023
There's only one adult game in the ranking of Steam's 100 most-wishlisted games and it's at number 25, above Homeworld 3, Darkest Dungeon 2, and Redfall. This is Operation Lovecraft: Fallen Doll , a 3D, Unreal Engine-powered game described on its Steam page as "a Cthulhu mythos inspired sex simulator and third-person sandbox.".. Read more.
- Closed Beta Progress Report - 30 January 2022
Issues to Address During the Rebuilding Thank you for taking part in the closed beta and providing valuable feedback! Before entering phase 2, a series of rebuilding and optimization work needs to be done to rectify the following issues detected in the first phase of closed beta: Horrendous performance for low to mid-tier PCs / Futureproofing The biggest issue in terms of time. Hard to say exactly how it'll affect things but potentially a delay to current plans to improve basic stability, optimization, and server handling. Pinpoint timeframe inexact but estimated 2 months at least. We don't like delays, but we feel it's ultimately necessary. We will still add new contents and updates to the current closed beta build before the reconstructing is complete. VR functionality Updated version is in development and not implemented yet, the team wasn't happy with how it was before. We aim to ad…
