@baishi256mk2 Hi, please submit a ticket on our discord server!

@PROJECT_H_Dev I received a test Key a few years ago, but Steam says the key has already been activated by another account. I have never successfully activated the Playtest. Could you please check the binding record and rebind or reissue the Playtest access?

The release of #OperationLovecraft update 0.8.9 marks the final test build solely focused on adding new characters. Update 0.9.0 will undergo a stress test on the closed beta branch to confirm if current server adjustments can support public testing traffic volume.

#OperationLovecraft closed beta 0.8.9 is now live on Steam. The next community-voted investigator, Yanshi the Inventor, has joined the squad!

Happy new year! We are moving full speed ahead with final testing for the next investigator: Yanshi. We expect this work to be completed by end of week. Stay tuned! #OperationLovecraft

Juzi's front and back view. Her sister Yanshi is coming to #OperationLovecraft next week!

🎄Merry Christmas!☺️

We managed to develop and implement a must-have feature for an adult game: a high quality real-time physics system of higher fidelity for cloth simulation in #UnrealEngine for #OperationLovecraft. The gap between the fabric and the skin is now greatly reduced without mesh clipping. #UE5

Don't forget to cast your vote in our community poll - it will decide which investigator is getting extra sex scenes in the future updates of #OperationLovecraft. #screenshotsaturday

We are adding a guarantee system in the next patch and you will get guaranteed new sex scenes after accumulating a certain amount of duplicate scenes. It's retroactive so your previous duplicates also count towards the guarantee.
