Will they ever make a grave encounters 3?

As of my knowledge limited to data available up until March 2023, there are no current plans or active developments for Grave Encounters 3. Grave Encounters 2, released in 2012, was the sequel to the original 2011 film. While the first movie received some positive reception and gained a cult following, the sequel did not perform as well critically or financially. As a result, there have been no substantial updates or announcements regarding a third installment in the franchise.

It's important to note that this information may have changed since then. For the most up-to-date information, I suggest checking official sources such as the production company or the filmmakers themselves through their social media or official websites.
