Good news, this is an original topic! I don't think there ever was, at least that I'm personally aware of.

I know that there was a mobile app game available on Apple devices (I'm not sure if Android had the game as well) before it was removed from the store like a decade ago. I believe it was a real world abnormal hunt game based on GPS like i.e. Pokemon Go. There was also an online game on Syfy.com called "Nubbin Hunt" that I think was an arcade style shooter. I've never personally played either game, so I can't say for certain exactly how those games functioned, but I do know that they definitely weren't RPG/board style games like D&D and Dune where a group of people sit down, adopt characters and role dice for story outcomes organized by a board master, etc..

That'd be really cool if there was. Unfortunately, it's up to the I.P. rights owner to agree to allow for such product to officially be made and licensed. The Beedie Group owned the rights completely until 2020. I'm not sure if a sale was actually made to fully transfer the I.P. from one owner to another, as the wording is a bit tricky, with a news article saying a "deal was inked". It could also simply mean that another company has a partnership/permission to be able to use the I.P. as well.

Normally in my professional experience if the term 'a deal was inked' it's quite basic or they want to keep the details quiet, however if the rights are transferred then they normally have to make it publicly available! I do have a contact who worked on sanctuary as a stuntie who I know, who might know more, I can try reaching out if you want!
