It’s sad that we will never see a Sleeping Dogs 2 now that United Front Games has officially gone out of business, but that doesn’t mean that we might not find something related to it.
A reddit user posted on the website they acquired a Playstation 4 dev kit that belonged to United Front Games. The dev kit contains 800GB of data on it, but it’s encrypted. This means that it could be very difficult to data mine. This isn’t a total lost cause as Assemble Games have come forth and said they are willing to help with the data mining process.
